ABSTRACT - Basing on literature data and unpublished relevés from Sicily, a survey of the syntaxa
belonging to the class Rumici-Astragaletea siculi Pignatti & Nimis 1980 em. Mucina 1997 (=
Cerastio-Carlinetea nebrodensis Brullo 1984) is presented. The class groups orophilous plant
communities dominated by hemicryptophytes and by dwarf-shrubs, often with a pulvinate and
thorny growth-form. The class is represented in Sicily by two orders: Rumici-Astragaletalia siculi
Pignatti & Nimis 1980, including the sole alliance Rumici-Astragalion siculi Poli 1965, restricted
to Mount Etna, and Erysimo-Jurinetalia bocconei Brullo 1984, including two alliances: the aci-
dophilous Armerion nebrodensis Brullo 1984 and the basiphilous Cerastio-Astragalion nebroden-
sis Pignatti & Nimis ex Brullo 1984. Within the class, nineteen associations have been recognized.
Nomenclature, floristic settlement, ecology and chorology are examined for each syntaxon. The
floristic autonomy of the class Rumici-Astragaletea siculi is examined from the phytogeographic
viewpoint and is confirmed by numerical analyses including not only the Sicilian phytocoenoses,
but also those occurring in Sila and Aspromonte (Calabria) and ascribed to the same class by
Brullo et al. (2001, 2004). It is, as well, highlighted that the Pollino massif represents the south-
ernmost limit to the distribution range of the class Festuco-Brometea, whose southward expansion
is hampered by the lack carbonatic highlands in the southernmost tip of the Italian Peninsula.
KEY WORDS - Sicily, orophilous vegetation, dwarf shrubs, phytosociology, Rumici-Astragaletea siculi.
INTRODUCTION
In the high mountain vegetation of Sicily, the most peculiar structural types are
extensively dominated by dwarf shrubs, often with a thorny and pulvinate habit.
These shrubs are particularly effective in retaining soil particles and organic matter
under their canopies, therefore providing a shelter from the harsh environmental
conditions to manifold herbaceous species (geophytes, therophytes and hemicryp-
tophytes). The vegetation at issue, in its typical aspect, forms spotted, discontinu-
ous layers on windy slopes and rocky habitats.
The high scientific attractiveness of this vegetation is given by the high num-
ber of endemic or relict species, a real highlight for Mediterranean phytogeogra-
phers, and by the morphologic and physiologic adaptations of chief species.
Several phytosociological data are available on this topic: Frei (1940) and Gilli
(1943) provided the fist contributions on the plant communities occurring in the
summit area of Etna. Afterwards, the orophilous vegetation of Etna was re-exam-
ined by Poli (1965) and by Pignatti et al. (1980) who first extended the survey to
the Madonie massif. In addition to the phytosociological treatment of the surveyed
vegetation, the latter contribution provided a peer analysis on the ecologic adapta-
tions, origin and chorologic features of the Central Mediterranean orophilous flora.
Further contributions on the Madonie highlands were provided by Raimondo
(1980) and by Brullo (1984), who proposed a new syntaxonomical survey of the
Sicilian orophilous dwarf vegetation.
Since then, with the exception of a phytosociologic map of Madonie (Raimondo
et al. 1994), no other contributions have been published on such an interesting
topic, although many additional data progressively accumulated in doctoral thesis
(Siracusa 1996; Guarino 1998; Giusso 2001; Cormaci 2001) and other specific
studies. On such basis, a general survey on the distribution of the orophilous dwarf
plant communities of Siciliy is presented here, by taking into account, as well, the
relationships with strictly allied communities of the siliceous massifs of Calabria.
STUDY SITES
The vegetation examined in this paper has a scattered distribution along the main
elevations of Sicily, wherever the altitude exceeds 1400 m a.s.l., with exceptional
descents at lower altitudes on windy, rocky ridges and summit outcrops. The surveyed
plant communities have their maximum diversity on Etna and Madonie, but they have
been recorded, as well, on Sicani, Nebrodi and Peloritani massifs (FIGURE 1):
– Etna is an active volcano, including the highest elevation of Sicily (currently 3314
m a.s.l.). In the summit area, the substrata are represented by volcanic scoriae,
lava flows and basaltic outcrops.
– Madonie are forming the highest part of the northern range of Sicily. This massif
includes several peaks higher than 1700 m a.s.l., the highest being Pizzo
Carbonara (1979 m a.s.l.). Many lithotypes are here represented, including
Mesozoic limestones and dolomites, quartzarenites, schists and flaky clays.
– Nebrodi are the longest part of the northern range of Sicily. The highest point is
Mt. Soro (1847 m a.s.l.) and the lithotypes of the summit areas are flysch with
sparse outcrops of Mesozoic limestones and siliceous metamorphic rocks.
Peloritani are the oldest part of the northern range of Sicily, chiefly formed by
siliceous rocks with different metamorphic degree. The vegetation at issue only
104
occurs on a small outcrop of Mesozoic limestones, forming the summit plateau of
Mt. Scuderi (1253 m a.s.l.).
– Sicani are the westmost massif of Sicily, quite isolated from the other high moun-
tains of the island. The highest peaks are Mt. Cammarata (1578 m a.s.l.) and
Rocca Busambra (1613 m a.s.l.), both made of Mesozoic limestones.
The surveyed plant communities grow on various substrata, with different pH
and granulometry, derived from the degradation of the above mentioned lithotypes.
The severe environmental conditions hamper the development of soils: the most
typical habitats of the vegetation at issue look very stony, although a feeble accu-
mulation of finer particles may occur under the shrubs. Grounds are often eroded
and, being scarcely developed, they are reflecting with unusual fidelity the chemi-
cal composition of the bedrock. All surveyed sites were very windy and exposed to
an intense solar radiation (Etna: Casa Cantoniera, 1882 m: 17830 kJ/m2); traces of
cryoturbation were evident at more than 1.700 m a.s.l.
The average year temperature in these habitats ranges between 3° and 11° C,
with average min. daily temperatures between 8° and 1.5° C and av. max. daily
temperatures between 17° and 26° C. The thermic excursion of the daily tempera-
tures averages between 13° and 25° C, while the yearly thermic excursion averages
between 19° and 34° C.
Rainfalls range between 800 and 1250 mm/yr, but their distribution shows the
neat gap in summer, that is typical of Mediterranean climates. The snow-deck is
rather changeable, depending on altitudes, topography and wind. The only available
record reports, on average, 3-4 months with snow-deck/yr (Etna, Casa Cantoniera,
1882 m a.s.l.).
Winds are rather frequent and strong, due to thermic and baric gradients. The
vicinity of the sea acts as a main environmental factor, especially in summer: the

moisty air, blown upwards by the sea breeze, is responsible for abundant dew in the
early morning, that partially buffers the summer drought (Pignatti et al. 1980).
Following the bioclimatic classification of Rivas-Martínez & Loidi Arregui
(1999), the surveyed plant communities find their optimal ecological requirements
within the supra- and oromediterranean thermotypes, but they are also occurring
within the supra-temperate submediterranean thermotype, limited to the Nebrodi
summits, and within the cryo-oromediterranean thermotype, on the top of Etna. The
ombrotypes range from subhumid to humid, depending on the altitude, on the expo-
sure and on the distance from the sea, with Nebrodi and Peloritani being the most
humid sites and Sicani the driest ones (Brullo et al. 1996).
MATERIAL AND METHODS
The present survey is based on literature data (305 relevés) and unpublished
ones (259 relevés), all from Sicily. In order to compare the vegetation at issue with
allied syntaxa described for Central-Southern Italy, further 307 relevés taken from
literature have been merged into synoptic tables, 56 of which from Sila Massif
(Central Calabria) and 70 from Aspromonte Massif (Southern Calabria).
Particular attention was paid to the relevés from Central and Southern Calabria,
because of the close affinity between the orophilous pulvinate vegetation of Sila and
Aspromonte with that of Sicilian mountains.
All relevés were sampled according to the Braun-Blanquet’s method (Braun-
Blanquet, 1964; Westhoff & van der Maarel, 1973). To compare the similarity across
the relevés, a multivariate analysis has been performed on a matrix of 213 species x
124 relevés, by means of the software package Syn-tax 5.1 (Podani, 1995).
The numerical analyses were based on presence/absence (binary) data. The
matrix was made of 60 relevés from Sicily and 64 from Calabria. The processed
relevés were selected across the whole data set, preferring those with the highest
floristic richness. To obtain the hierarchical clustering, the Sørensen algorithm was
adopted as resemblance coefficient and the single link was adopted as distance-
optimizing method. A Principal Components Analysis (PCA) has been performed
too, aiming to detect ecological gradients related to the data set.
Besides, a second numerical analysis was performed by the same methodology
on a matrix of 62 relevés x 226 species, in order to compare the relevés of Sicily,
Aspromonte and Sila with some relevés sampled in the orophilous hemicrypto-
chamaephytic vegetation of Central and Southern Apennines. This was aimed to
sound out the floristic autonomy of the issued vegetation with respect to that of the
southernmost massifs of the Apenninic range.
The floristic analysis was based on the taxa listed in the phytosociological tables.
The Raunkiaer’s classification of the growth forms was followed in the biological
spectrum and the chorologic types proposed by Brullo et al. (1998) were adopted in
the chorological spectrum.
For the critical examination of the surveyed syntaxa, the international code of
phytosociological nomenclature was followed (Weber et al.,2000). The taxonomic
nomenclature follows Pignatti (1982), in some cases partially updated on the basis
of more recent papers: Stipa sicula Moraldo, Galium venustum Jordan, Scleranthus

venustus Rchb., Bellardiochloa violacea (Bellardi) Chiov., Bellardiochloa aetnen-

RESULTS
The orophilous pulvinate vegetation of Sicily is characterized by a pool of
species having a remarkable phytogeographical interest. The chorologic spectrum

phytes; Ch: chamaephytes; H: hemicryptophytes; G: geophytes; T: therophytes).
(FIGURE 2) highlights a 35.4% of endemic taxa, of which 21% restricted to Sicily.
The Mediterranean element includes 49.4% of the sampled flora, that is chiefly rep-
resented by Circum-Mediterranean taxa (21%).
With reference to the life-forms spectrum displayed in FIGURE 3, the surveyed
vegetation is clearly dominated by hemicryptophytes (42.8%) and chamaephytes
(31%). These two groups are not only the richest in species, but also including the
species characterizing the physiognomy of these plant communities.
The syntaxonomical treatment of this vegetation has been quite controversial, up
to a recent past, probably because the whole perspective was missing, as most of the
published data focussed on Etna and/or Madonie. At first, three associations from
Etna have been validly published by Frei (1940), two of which revived by Gilli
(1943), Lüdi (1956) and Poli (1965). The last author, in particular, was the first who
highlighted how problematic was the framing of the orophilous pulvinate associa-
tions of Etna into any of the known higher syntaxa. She therefore proposed a new
alliance, Rumici-Astragalion siculi, and postulated the occurrence of a new order,
proposed by Giacomini under the provisory name of Astragaletalia siculae.
Pignatti et al. (1980) proposed the new class Rumici-Astragaletea siculi, where
the Etnean vegetation belonging to Rumici-Astragalion siculi was included. The
same authors, who investigated, as well, the orophilous pulvinate vegetation of
Madonie, ascribed them the classes Ononido-Rosmarinetea and Cisto-
Lavanduletea, on the basis of a somewhat physiognomical convergence, due to the
presence of very few and sporadic character species of these two classes. In par-
ticular, the recorded basiphilous communities were included in an endemic
alliance, Cerastio-Astragalion nebrodensis, framed into the order Erinacetalia;
while the two acidophilous association, exclusively on the basis of their ecology,
were referred with some perplexities one (Genistetum cupanii) to the Cisto-
Lavanduletea and the other (Plantagini-Armerietum nebrodensis) to the Trifolion
humilis (Erinacetalia).Successively Brullo (1984), in a study about the vegetation
of Madonie, emphasized the importance of a group of endemic taxa common to all
the Sicilian high mountains and noted that the occurrence of these species was
largely superior in number and cover abundance than the occurrence of those char-
acterizing the two classes considered by Pignatti et al. (1980). He therefore pro-
posed a new class, Cerastio-Carlinetea nebrodensis, including all the Sicilian
hemicrypto-chamaephytic orophilous vegetation. The possibility to emend the
name Rumici-Astragaletea siculi, by following the Art. 47 of the code, was actual-
ly considered unproper by Brullo because it was explicitly excluded by Pignatti et
al. (l.c.)that the Etnean class could include, as well, the communities of Madonie.
Moreover, the species choosen by Pignatti for the name Rumici-Astragaletea siculi
are endemic to Etna and therefore not really suitable for a class including all the
Sicilian communities. Mucina (1997) had a different opinion: in a survey of the
European phytosociological classes, he emended the Rumici-Astragaletea siculi
and included within this class the Cerastio-Carlinetea nebrodensis.
Within this class, two orders can be recognized (FIGURE 4): one restricted to
Etna, Rumici-Astragaletalia siculi with the sole alliance Rumici-Astragalion siculi,
and one stretched over the heights of the mountains of Northern Sicily, Erysimo-
Jurinetalia bocconei, with two alliances: one basiphilous (Cerastio-Astragalion
nebrodensis) and one acidophilous (Armerion nebrodensis).
108
More recently, the range of this class have been enlarged up to the siliceous mas-
sifs of Calabria (Brullo et al. 2001, 2004), where an independent order have been
recognized (Anthemidetalia calabricae), comprising two alliances, one limited to
the Aspromonte heights (Armerion aspromontanae) and one restricted to Sila
(Koelerio-Astragalion calabrici).
This syntaxonomic arrangement is well supported by the cluster diagram in
FIGURE 5, where the first three branches correspond to the orders and the five
alliances merge at more than 0.45 dissimilarity index. The PCA (FIGURES 6-7)
confirms the segregation of these groups also from the ecological viewpoint. In
particular, the first axis could be related to a gradient of water availability, iden-
tifying the phytocoenoses belonging to the Aetnean alliance as the most
edaphoxerophilous (they are growing under dry ombrotypes, on mineral terrains,

whose water capacity is very low), and those of Sila as the most edaphohy-
grophilous (they are growing under humid ombrotypes, on relatively deep and
moisty granitic soils). The second axis could be related to the meteoric alteration
of the soils, that is very low on Etna (where substrata are constantly renewed by
the volcanic activity) and on Sila (where the incoherent substrata, deriving from
the alteration of old granites, crumble very easily and are quickly eroded by the
weathering), while it is relatively high on Aspromonte and on the siliceous tops
of Madonie, where substrata are altered by very slow pedogenetic processes, act-
ing since ancient times on the flattened plateaux that are typical of these massifs.
The third axis could be related to the pH of the substrata, identifying the phyto-
coenoses belonging to the Rumici-Astragalion siculi as the most acidophilous
and those belonging to Cerastio-Astragalion nebrodensis as the most
basiphilous.

STRUCTURE AND ECOLOGY:Heliophilous vegetation dominated by hemicriptophytes,
pulvinate chamaephytes and nanophanerophytes, colonizing initial soils derived
from limestones, dolomites, quartzites, granites, metamorphic and volcanic rocks.
The habit of the chief species let them to tolerate the strong winds and the seasonal
drought stress characterizing their growing sites, represented by summit plateaux,
slants and ridges. The communities of this class, even if primarily colonizing the
summit extension above the timber-line, or rocky outcrops in the altitudinal belt of
the orophilous woodlands, largely occur on eroded soils and debris in secondary
habitat created by the human or the volcanic activity. The bioclimatic belts relat-
ed to this vegetation are between the supra- and the cryo-oromediterranean.
DISTRIBUTION:High mountains of Sicily (Sicani, Madonie, Nebrodi, Etna,

STRUCTURE AND ECOLOGY: pulvinate vegetation, forming a patchy layer, 30-50 cm
high. The peak of the flowering time happens around the mid of June. This asso-
ciation is remarkably pioneer, colonizing volcanic sands, eroded soils and stony
slopes in windy sites. In optimal conditions, this vegetation normally reaches very
high cover values. The structure is given by the dominance of the big thorny pul-
vines of Astragalus siculus, having the maximum spread within the supra- and
oromediterranean belt (altitudinal range: 1500-2200 m a.s.l.). The association can
be found, however, at lower altitudes in secondary habitats.

STRUCTURE AND ECOLOGY:hemicrypto-chamaephitic vegetation, forming a discon-
tinuous layer, 5-15 cm high. The peak of the flowering time happens in July. The
association represents the highest altitudinal record of the Sicilian vegetation: it
has its optimum in the cryo-oromediterranean belt (2200-2900 m a.s.l.), where it
vicariates the Astragaletum siculi. The association may also occur at lower alti-
tudes, on volcanic sands, where it represents a seral stage, dynamically preceding
the Astragaletum siculi.

CHARACTER SPECIES: Bellardiochloa aetnensis (dom.).
STRUCTURE AND ECOLOGY: discontinuous vegetation dominated by caespitose
hemicryptophytes, forming a patchy layer, 5-15 cm high. The peak of the flower-
ing time happens around the mid of June. The association dwells markedly erod-
ed soils and rocky slopes on windy ridges and at the basis of the volcanic dykes.
The altitudinal range of the association is between 1700 and 2300 m a.s.l.; being
the optimal aspects included in the oromediterranean belt.
DISTRIBUTION: Etna (Eastern Sicily).
NOTE:This vegetation was described first by Frei (1940) as “association with Poa
aetnensis and Festuca nebrodensis”. The name proposed by Frei must be correct-
113
ed (art. 43) because Festuca circummediterranea has been mistakenly determined
as F. nebrodensis, while Poa aetnensis, for the unkeeled lemma and the strictly
conduplicate leaves must be ascribed to the genus Bellardiochloa (Chrtek, 1970).

(353): 324.
HOLOTYPUS: TABLE 1, rel. 1, in Siracusa (1998).
CHARACTER SPECIES: Secale strictum.
STRUCTURE AND ECOLOGY: hemicryptophytic vegetation forming a continuous layer,
40-60 cm high. The structure is given by the dominance of two big caespitose
grasses, that are particularly successful in colonizing flat or gently sloping sites,
where volcanic sands and finer particles can accumulate. The peak of the flower-
ing time happens around the mid of June. This vegetation requires hollowed sites,
not very windy, relatively moist substrata. When the environmental factors
become more extreme, the association is replaced by the Astragaletum siculi. The
association occurs in the supra- and oromediterranean belts (altitudinal range:
1500- 1900 m a.s.l.) but it can also be found at lower altitudes in forest clearings.
DISTRIBUTION: Etna (Eastern Sicily).
Festuco circummediterraneae-Populetum tremulae Brullo & Siracusa ass. nov.
(TABLE 4).
HOLOTYPUS: TABLE 4, rel. 6, hoc loco.
CHARACTER SPECIES: Populus tremula f.ma nana.
STRUCTURE AND ECOLOGY:nanophanerophitic vegetation forming a patchy layer, 30-
50 cm high. The peak of the flowering time happens at the end of June. The asso-
ciation colonizes lavic sheers, with a sloping angle of 30°-40°, covered by a thin
layer of volcanic sand, that is kept permanently humid by the water deriving from
the snow-melting. The water cannot percolate through the sheers, and soaks up the
sand accumulated against volcanic dykes, that shelter the slopes from the dry
north-westerly wind. This microhabitat occurs in the cryo-oromediterranean belt,
between 2300 and 2400 m a.s.l., and is successfully colonized by Populus tremu-
la, that at these heights puts on a prostrate-pulvinate dwarf growth form.
DISTRIBUTION: restricted to a small area of the southern flank of Etna (Timpa

STRUCTURE AND ECOLOGY: xerophilous association forming a discontinuous layer,
20-45 cm high. It colonizes lithosoils on rocky slopes and eroded sites. The rich
floristic settlement is caracterized by the codominance of hemicriptophytes and
chamaephytes, normally equally distributed, although Sesleria nitida ssp. sicula
may become dominant. The peak of the flowering time happens at the beginning
of June. The ecological optimum is in the supramediterranean belt (altitudinal
range: 1200-1800 m a.s.l.).
DISTRIBUTION: Madonie, on carbonatic outcrops.

CHARACTER SPECIES:Carduncellus pinnatus, Scorzonera villosiformis, Teucrium

STRUCTURE AND ECOLOGY:vegetation dominated by chamaephytes, normally with a
prostrate growh, forming a discontinuous layer, 20-35 cm high. The peak of the
flowering time happens in June. Cover values are rather changeable, depending on
the intensity of the pasturage. This association colonizes debris and eroded soils
derived from flaky clays, flysch, limestones and dolomites, always characterized
by a relevant percentage of silt and clay. Colonized sites are often windy, gently
sloping summits, in the meso- and supramediterranean belt (altitudinal range:
1100-1400 m a.s.l.).
DISTRIBUTION:Madonie (namely on Mt. Quacella); Sicani (Mt. delle Rose, Mt.
Cammarata, Rocca Busambra); Nebrodi (common on eroded slopes and flysch
outcrops, although floristically quite poor).

58 (TABLE 8).
HOLOTYPUS: TABLE 7, rel. 66, in Pignatti et al. (1980).
CHARACTER SPECIES: Astragalus nebrodensis (dom.), Dianthus siculus.
STRUCTURE AND ECOLOGY: Markedly pioneer association, colonizing eroded soils
rich in skeleton, stony slopes and windy ridges. This vegetation forms a patchy
layer, 30-70 cm high. The peak of the flowering time happens around the mid of
June. The extreme environment is responsible for a relatively poor floristic settle-
ment, and a large amount of the total biodiversity is found inside the pulvines of
Astragalus, whose thick cushions shelter the other species from the strong wind
and let a slight accumulation of organic matter. The optimal aspect of the associa-
tion is in the supramediterranean belt, even if, sometimes, this vegetation can be
found at lower altitudes, in secondary habitats, on steep eroded slopes. The altitu-
dinal range is between 1400 and 1900 m a.s.l.
DISTRIBUTION: Madonie, on carbonates and flaky clays.

116
CHARACTER SPECIES: Cachrys ferulacea (dom.), Astragalus depressus var. leu-
cophaeus.
STRUCTURE AND ECOLOGY: Among the association belonging to the Cerastio-
Astragalion nebrodensis, this is one of the most mesophilous and nitrophilous, as
it prefers north-facing gently-sloping sites, with relatively deep soils with a fairly
good hydratation up to the late summer, due to an intense moisture condensation
and relatively frequent rains. Nevertheless, it is linked to rocky, karstic habitats,
with very primitive soils. The structure is given by the dominance of Cachrys fer-
ulacea, a big hemicriptophytes, that covers from 30 up to 80% of the ground. The
peak of the flowering time happens around the mid of June. The altitudinal range
is between 1600 and 1900 m a.s.l., in the oromediterranean belt.
DISTRIBUTION: Madonie, namely Pizzo Carbonara, Monte Mufara and Monte dei Cervi.
NOTE: in the original description, within this association, three subassociations were
recognized (Raimondo, 1980): typicum, artemisietosum albae and vicietosum glau-
cae. The subassociation typicum is a result of the overgrazing affecting the Madonie
heights, that enhances the growth of Cachrys ferulacea, an unpalatable, feebly
nitrophilous species. The other two subassociations, both characterized by the pres-
ence of Artemisia alba, are growing in primary habitats, represented by steep and
stony slopes. To give more emphasis to the well defined ecologic requirements of
Artemisia alba, in Sicily extremely rare and localized, it is here preferred to attrib-
ute the rank of association to the vegetation characterized by this species.

CHARACTER SPECIES: Artemisia alba, Verbascum siculum, Sternbergia exscapa.
STRUCTURE AND ECOLOGY: This subassociation, corresponding to the typical aspect
of the association, colonizes stony carbonatic substrata, on steep and windy slopes
(sloping angle up to 50°), between 1500 and 1900 m a.s.l., in the oromediterranean
bioclimatic belt. This vegetation forms a discontinuous layer, 20-40 cm high, dom-
inated by chamaephytes and caespitose hemicriptophytes. The peak of the flower-
ing time happens at the end of June. This association turns into the previous one
on less steep slopes and by the increase of the grazing pressure.
DISTRIBUTION: Madonie, namely Pizzo Carbonara.

HOLOTYPUS:TABLE 5, rel. 3, in Raimondo (1980).
SYN.: Cachryetum ferulaceae vicietosum Raimondo 1980, CNR AQ/1/89: 22.
CHARACTER SPECIES:Vicia glauca.
STRUCTURE AND ECOLOGY:This vegetation type substitutes the previous one on
screes and karstic crests. In this context, the plant density is lower and their height
117
usually does not exceed 30 cm. Hemicryptophytes are more abundant than
chamaephytes and the occurrence of Vicia glauca, a rare orophyte restricted to the
carbonatic mountains of Atlas, Sicily and Sardinia, clearly identifies this subasso-
ciation.
DISTRIBUTION:Madonie, namely Pizzo Carbonara. This subassociation can be con-
sidered a Sicilian vicariant of Cerastio supramontani-Helianthemetum crocei,
belonging to the alliance Polygalo sardoae-Seslerion barbaricinae (Carici-
Genistetea lobelii), restricted to the carbonatic relieves of Sardinia (Arrigoni & Di
Tommaso 1991).

STRUCTURE AND ECOLOGY: discontinuous vegetation dominated by caespitose
hemicryptophytes, forming a patchy layer, 10-20 cm high. The peak of the flow-
ering time happens around the mid of June. The association dwells rocky carbon-
atic slopes on windy ridges, in the oromediterranean belt (altitudinal range 1800-
1950 m a.s.l.). On more stony and less steep sites, this association turns into the
Sideritido siculae-Artemisietum albae.
DISTRIBUTION: Madonie, namely Pizzo Carbonara.
Peucedanetum nebrodeFnsis Brullo & Giusso ass. nova (TABLE 12).
HOLOTYPUS: TABLE 12, rel. 8, hoc loco.
CHARACTER SPECIES: Peucedanum nebrodense.
STRUCTURE AND ECOLOGY: This association occurs in small depressions and around
the inner slopes of the dolines with northern exposure, where it forms a dense
layer, interrupted only by small outcrops of rocks. This vegetation benefits of a rel-
atively good accumulation of fine particles and organic matter. In these habitats,
the snow-bed lasts for quite a long time and the hydratation of the soil is fairly
good up to the late summer. The association is linked to the omediterranean belt
(altitudinal range: 1800-1900 m a.s.l.) and the peak of the flowering time happens
at the end of July, up to the mid of August.
DISTRIBUTION: Madonie, namely Pizzo Carbonara.

STRUCTURE AND ECOLOGY: discontinuous vegetation dominated by caespitose
hemicryptophytes, forming a dense layer, 25-40 cm high. The peak of the flower-
ing time happens at the beginning of June. The association occurs in secondary
habitats, related to the irreversible degradation of woodlands, where it dwells
heavily eroded soils on carbonatic slopes. The association finds its optimum in the
supramediterranean belt (altitudinal range 1300-1570 m a.s.l.), although it may
also occur at lower altitudes, where it merges into more thermophilous dry grass-
lands, dominated by Ampelodesmos mauritanica.
DISTRIBUTION: Sicani.

STRUCTURE AND ECOLOGY: vegetation dominated by caespitose hemicryptophytes,

around the mid of June. The association dwells rocky carbonatic slopes on windy
ridges, in the supramediterranean belt (altitudinal range 1300-1570 m a.s.l.). On
screes, this association shifts towards glareicolous communities belonging to the
alliance Linarion purpureae (Scrophulario-Helichrysetea italici).
DISTRIBUTION: This association, for its structure and adaptative behaviour, can be
seen as an ecological vicariant, on Sicani, of Seslerio siculae-Melicetum cupanii.
Helichryso italici- Onosmetum canescentis Brullo & Guarino ass. nova (TABLE 15).
HOLOTYPUS: TABLE 15, rel. 4, hoc loco.
CHARACTER SPECIES: Onosma canescens (dom.), Helichrysum italicum (diff.),
Festuca nigrescens ssp. microphylla (diff.).
STRUCTURE AND ECOLOGY: Hemicrypto-chamaephytic vegetation, forming a discon-
tinuous layer, 20-25 cm high. The peak of the flowering time happens at the begin-
ning of June. The habitat is constituted by carbonatic screes and steep rocky
places, between 980 and 1140 m a.s.l.. The bioclimatic type is supramediterranean
lower humid. Within the association, two facies can be recognized, one character-
ized by Lomelosia crenata ssp. hirsuta, that is typical of rocky habitats, and one
by Pimpinella tragium var. glauca, Euphorbia myrsinites and Galium venustum,
tipically occurring on screes.
DISTRIBUTION: this association has been observed around the summit of Mt. Scuderi
(Peloritani), and it can be considered a local vicariant of the Lino-Seslerietum niti-
dae. The lower altitude of Mt. Scuderi does not allow the growth of many of the
orophytes characterising the latter association, the occurrence of Helichrysum
italicum as differential species is a further proof of the relative xero-thermophily
of the association at issue. Although the character species of Erysimo-Jurinetalia
bocconei are poorly represented on Mt. Scuderi, this mountain has got an high
phytogeographic interest, because it represents the easternmost outpost of the dis-
tribution range of the above mentioned order, having its barycentre on Madonie,
where the higher elevations better satisfy the ecological requirements of the vege-
tation at issue. It is likely that, during the Messinian age, the indirect uplift of the
mountains enabled the vegetation belonging to this order to form a continuous belt
along the mountain ranges of northern Sicily, of which the Helichryso italici-
Onosmetum canescentis represents a last, floristically poor, fragment.
Plantagini humilis-Asperuletum gussonei Brullo & Guarino ass. nova (TABLE 16).
HOLOTYPUS: TABLE 16, rel. 2, hoc loco.
CHARACTER SPECIES:Plantago humilis, Asperula gussonei.
STRUCTURE AND ECOLOGY: Hemicrypto-chamaephytic vegetation, forming quite a
continuous layer, 5-15 cm high. The peak of the flowering time happens at the
beginning of June. The habitat is constituted by flattened or stepped outcrops of
carbonatic rocks, between 1100 and 1253 m a.s.l.. The bioclimatic type is
119
supramediterranean lower humid. Both the character species are rather untypical
of this ecological context: Asperula gussonei is well known as an orophilous cal-
ciphilous chasmophyte, endemic to Northern Sicily, where it is a member of
Asplenietea trichomanis-vegetation, while Plantago humilis is a calcifuge pulv-
inated chamaephyte, normally growing on siliceous substrata.
DISTRIBUTION:this association has been observed on the summit of Mt. Scuderi
(Peloritani), and it can be considered an edaphic vicariant of the Plantagini
humilis-Armerietum nebrodensis. Both these associations are phisiognomically
characterized by Plantago humilis, but on Mt. Scuderi the species composition is
formed by a pool of calciphilous elements that are missing on the quartzarenitic
outcrops of Madonie, where Plantago humilis finds its optimal ecological require-
ments. It is likely that during the Messinian Age, and, perhaps, even during some
phases of the Quaternary glaciations, Pl. humilis was well represented along the
siliceous ridge of Peloritani. This species is nowadays confined to the small car-
bonatic outcrop of Mt. Scuderi by the relatively low elevation of the Peloritani
range, that reduces the chances of this pioneer but poorly competitive species.

STRUCTURE AND ECOLOGY:patchy vegetation dominated by small pulvinate chamae-
phytes and caespitose hemicriptophytes. The peak of the flowering time happens
at the end of June. This phytocoenosis dwells markedly eroded soils on sunny
plateaux and windy ridges. The altitudinal range of the association is between
1700 and 1900 m a.s.l., in the oromediterranean belt. The soils colonized by this
vegetation are extremely leached and acid (pH: 5,4-6), often altered by cryoturba-
tion. Owing to the aeolic erosion, the habitat looks very stony, even there is a fee-
ble but constant accumulation of fine sediments under the surface, where a very
slow pedogenesis may explain the acidity of the soil (Pignatti et al. 1980).
DISTRIBUTION: Siliceous peaks of Madonie, namely on Mt. San Salvatore and

STRUCTURE AND ECOLOGY:This association finds its primary habitats on quartzitic
sunny slopes where the pedogenesis is hindered, but nowadays it covers large
areas in secondary habitats, where it plays a role in the dynamic processes linked
to the degradation of orophilous woodlands. The physiognomy of the association
is given by the growth-form of Genista cupanii, a nanophanerophyte forming
dense pulvines up to 1 m in diameter and 60 cm high. This vegetation is linked to
the supramediterranean bioclimatic belt, between 1100 and 1700 m a.s.l., and the
peak of the flowering time happens in June.
DISTRIBUTION:Siliceous peaks of Madonie.
DISCUSSION
Rumici-Astragaletea siculi is a narrowly ranging class, having a spotted distri-
bution on the highest mountains of Sicily, Central and Southern Calabria. The class
is clearly outlined by a group of orophytes that, becoming isolated in their restrict-
ed habitats at the end of the Tertiary, originated many vicarious populations, often
endemic to a sole mountain (TABLE 19). In FIGURE 8, the ranges of the most frequent
species in the surveyed vegetation are displayed. These orophytes confer to the
plant communities where they are dominating a strong phytogeographic connota-
tion (TABLE 21).
As a consequence of the Messinian Age, something similar happened all around
the Mediterranean basin, giving rise to an interesting system of vegetation com-
plexes, similar in their ecological specialization, structure and physiognomy, but
having such a remarkable floristic autonomy that justify the phytosociological treat-
ment as different classes, each endemic to a well defined Mediterranean mountain
district. Among these: Carici-Genistetea lobelii Klein 1972 em. Pignatti & Nimis
1980, endemic to Corsica and Sardinia; Saturejetea spinosae Zaffran 1990, endem-
ic to Crete; Diantho troodi-Teucrietea cyprii Brullo, Giusso & Guarino 2005,
endemic to Cyprus; Daphno-Festucetea Quézel 1964, endemic to the Southern
Balcans and SW Anatolia; Astragalo-Brometea Quézel 1973, endemic to Anatolia
and Lebanon.
On Etna, Madonie, Aspromonte and Sila, the vegetation of Rumici-Astragaletea
siculi is often contiguous to Pino-Juniperetea communities, which can be seen as
the last remains of a vegetation dominating the oro-Mediterranean belt before the
Messinian Age (Brullo et al., 2001). In spite of the spatial contiguity, pulvinate
communities are well distinct from those dominated by conifers, both considering
the structural differences and the ratio of species diversity, as already noted by some
authors in other Mediterranean districts (Rivas-Martínez 1964; Barbero & Quèzel
1975; Quèzel & Barbero 1989; Stanisci 1997; Rivas-Martínez et al. 2001). In a
recent survey on the Italian woods, Pignatti (1998) proposed to include the vegeta-
tion dominated by Pinus laricio in Calabria and Etna within the class Rumici-
Astragaletea siculi. In our opinion, this syntaxonomical treatment disregards the
121
different history and structure of the fragmentary plots dominated by conifers and
gives too much emphasis to the occurrence of species having their ecological opti-
mum in the neighbouring vegetation, although sporadically occurring, as well, in
the Pinus laricio-communities.
Some years ago, it was proposed by Biondi et al. (1995) to ascribe one of the
associations treated in this paper, Lino punctati-Seslerietum siculae,to the alliance
Phleo ambigui-Bromion erecti. This alliance is grouping basiphilous herbaceo-
chamaephytic communities of Central and Southern Apennines, stretching up to the
Pollino massif, which represents the most notable biogeographic limit for many
orophilous Apenninic species.
Among the species characterising the Festuco-Brometea class, only Phleum
ambiguum has a fairly good presence in the Calabrian and Sicilian communities,
while few others (Artemisia alba, Bromus erectus, Carlina acanthifolia, Galium
lucidum and Teucrium montanum) are very rare and localized (TABLE 20). The pro-
posal of Biondi et al. (l.c.) is therefore not very sound, also on the basis of a numer-
ical analysis, that was performed in order to compare the syntaxa of Rumici-
Astragaletea siculi to the most representative orophilous pytocoenoses of Festuco-
Brometea, occurring in central and southern Apennines. The cluster diagram in
FIGURE 9clearly shows how different are the relevés belonging to these two classes.
The class Rumici-Astragaletea siculi, like the allied endemic classes described
for the other big mediterranean islands, represents a meanigful patch to understand
the biogeographical history of the Mediterranean area. Its communities, nowadays
extremely rare and isolated, are precious relict examples of the Tertiary
Mediterranean vegetation, in Southern Europe nearly completely erased by the gla-
cial age.

... It is endemic of the north-eastern part of Sicily (Etna, Madonie, Nebrodi and Peloritani), where it prefers acidic substrates such as flysch, sand- stons and volcanic rocks (Schicchi, 2004;Giardina et al., 2007). Brullo et al. (2005) considered it as a char- acteristic species of the Rumici-Astragaletalia siculi Pignatti & Nimis in Pignatti et al. 1980 (cl. RumiciAstragaletea siculi). It was also considered (Brullo & Marcenò, 1985) & Foggi, 2015;Banfi et al., 2017). ...
... Previously, however, Biondi et al. (1995) had already considered the Festuco-Brometea as occurring in Sicily, on the basis of their classifica- tion of the Madonie's dry grassland Lino-Seslerietum in the Phleo ambigui-Bromion (this latter alliance being included in the Festuco-Brometea). In fact, however, this association was originally classified in the Rumici-Astragaletea ( Pignatti et al. 1980) and Cerastio-Carlinetea (Brullo 1984;Brullo et al. 2005). The Biondi et al. (1995) classification was presum- ably based on two considerations. ...

A phytosociological study on the Brachypodium rupestre grasslands in Sicily is presented. These grasslands form discontinuous secondary stands dynamically linked to the deciduous oak woods, which are widespread within the upper-colline, submontane and lower montane belts (800-1400 m) of the Tyrrhenian side of the northern Sicily and in the Sicani mountains. In the study area B. rupestre grasslands were mainly found in colluvial plains or drainage lines where relatively deep and mesic soils occur. In this paper 42 phytosociological relevés were performed and statistically analysed. Two new associations were described and classified in the alliance Polygalo mediterraneae-Bromion erecti (Brometalia erecti, Festuco-Brometea): Lolio pluriflori-Brachypodietum rupestris and Tanaceto siculi-Brachypodietum rupestris. The Lolio pluriflori-Brachypodietum is typical of the limestone substrates of Nebrodi, Madonie and Sicani mountains and of the mounts surrounding Palermo and Trapani. Two subassociations (typicum and violetosum ucrianae) and an impoverished variant rich in therophytes have also been identified. The Tanaceto siculi-Brachypodietum is restricted to the metamorphic substrates of the Peloritani mountains on the northeastern side of the island. Finally the association Polygalo mediterraneae-Brachypodietum rupestris, which was only provisionally described in 2014 for the Lucanian Apennines (Peninsular Italy), has been validated here.

Question Cushion‐forming vascular plants are adapted to alpine environments and act as ecosystem engineers by moderating microclimate and creating a fertility island under their canopy. Most of the available studies on cushion ecology have been devoted to plant facilitation, but none used a holistic approach that considers the response of co‐existing plant species with other key ecosystem players. Here, we quantified the biogenic effect and facilitation capacity of Astragalus siculus , a spiny nitrogen‐fixing cushion plant, and test the hypothesis that the facilitation effect would increase with elevation as stress gradient. Location Mount Etna, the highest active volcano in the Mediterranean Basin. Methods We combined chemical characterization of the soil with a description of the soil microbiota by high‐throughput sequencing of bacterial and eukaryotic rRNA gene markers carried out at three elevations, that is 1650, 1900 and 2210 m a.s.l. In addition, we analysed the microclimate outside and inside the Astragalus canopy to assess the linkages between above‐ and below‐ground ecosystem compartments and quantified the occurrence of co‐existing vascular plants. Results Astragalus cushions have strong biogenic effects on above‐ and below‐ground conditions by dramatically increasing soil organic carbon and total nitrogen stocks at 1900 and 2210 m elevation. Moreover, a buffering of soil temperature and moisture regimes was recorded, with lower temperatures in summer but higher in winter inside the cushions. Cushions harbour a specific bacterial and fungal microbiota compared to external bare soil. Stem density and cushion height increase significantly with altitude, as does the nurse effect of the cushion on the growth and survival of co‐existing vascular plants. Conclusions As a result of cushion biogenic environmental changes, the effect of Astragalus on some of the co‐existing species shifted from negative or null at 1650 m to facilitative along the elevation gradient. Furthermore, our data show a relationship between Astragalus morphological traits and soil biogenic changes related to soil chemistry and microbiota that affect plant interaction and coexistence.
... Fundamental was the collection of floristic observations, sampled during the last twenty years all around the volcano in the form of phytosociological relevés, georeferenced floristic records, field notes, etc. Moreover, several papers, regarding the plant communities of this territory, were consulted (Brullo et al., 1999;Brullo, Giusso del Galdo & Guarino, 2001;Brullo, Marcenò & Siracusa, 2004;Brullo et al., 2005;Brullo et al., 2007;Brullo et al., 2008;Brullo et al., 2010;Brullo et al. 2012;Brullo et al., 2013b;Brullo & Marcenò, 1985a;Brullo & Marcenò, 1985b;Brullo & Siracusa, 2000;Di Benedetto, 1981;Furnari & Scelsi, 1993;Gianguzzi, Cusimano & Romano, 2014b;Giusso del Galdo & Brullo, 2012;Grillo, 1975;Maugeri, 1980;Maugeri et al., 1979;Poli, 1965;Poli & Grillo, 1975;Poli & Maugeri, 1974;Poli, Lo Giudice & Ferlito, 1979). More than 2,000 phytosociological published relevés were examined. ...

Background Altitudinal variation in vascular plant richness and endemism is crucial for the conservation of biodiversity. Territories featured by a high species richness may have a low number of endemic species, but not necessarily in a coherent pattern. The main aim of our research is to perform an in-depth survey on the distribution patterns of vascular plant species richness and endemism along the elevation gradient of Mt. Etna, the highest active volcano in Europe. Methods We used all the available data (literature, herbarium and seed collections), plus hundreds of original (G Giusso, P Minissale, S Sciandrello, pers. obs., 2010–2020) on the occurrence of the Etna plant species. Mt. Etna (highest peak at 3,328 mt a.s.l.) was divided into 33 belts 100 m wide and the species richness of each altitudinal range was calculated as the total number of species per interval. In order to identify areas with high plant conservation priority, 29 narrow endemic species (EE) were investigated through hot spot analysis using the “Optimized Hot Spot Analysis” tool available in the ESRI ArcGIS software package. Results Overall against a floristic richness of about 1,055 taxa, 92 taxa are endemic, of which 29 taxa are exclusive (EE) of Mt. Etna, 27 endemic of Sicily (ES) and 35 taxa endemic of Italy (EI). Plant species richness slowly grows up to 1,000 m, then decreases with increasing altitude, while endemic richness shows an increasing percentage incidence along the altitudinal gradient (attributed to the increased isolation of higher elevation). The highest endemic richness is recorded from 2,000 up to 2,800 m a.s.l., while the highest narrow endemic richness (EE) ranges from 2,500 up to 2,800 m a.s.l. Life-form patterns clearly change along altitudinal gradient. In regard to the life-form of the endemics, the most represented are the hemicryptophytes, annual plants (therophytes) are prevailing at lower altitudes and show a decreasing trend with increasing elevation, while chamaephytes are featured by an increasing trend up to 3,100 m of altitude. Furthermore, the results of the hotspot analysis emphasize the high plant conservation priority areas localized in oro-mediterranean (1,800–2,400 m s.l.m.) and cryo-mediterranean (2,400–2,800 m) bioclimatic belts, in correspondence of the oldest substrates of the volcano. Conclusions High plant speciation rate caused by increasing isolation with elevation is the most plausible explanation for the largest active volcano in Europe. The high degree of endemic species on Mt. Etna is linked to its geographical, geological and climatic isolation, all important drivers of speciation acting on the population gene flows. The hot spot map obtained represents a useful support for help environmental decision makers to identify priority areas for plant conservation.
... The past occurrence of currently submerged stepping stones may also explain the pre- sence of many species that spread in the Mediterranean basin during the Messinian sali- nity crisis and that could not have been surviving in situ on Sicily, given its submersion until relatively recent times. This is the case of vegetation types to which the following phytosociological units, currently well represented in Sicily, are referring: Pegano har- malae-Salsoletea vermiculatae ), Saginetea maritimae (BRULLO & GIUSSO DEL GALDO 2003), Salicornietea fruticosae and Juncetea maritimi (BRULLO & FURNARI 1976), Rumici-Astragaletea siculi (BRULLO et al. 2005) and the perennial steppe prairies of Moricandio-Lygeion sparti (BRULLO et al. 2010). All these syntaxa, related to salty substrata or to mountain debris and talus slopes, are characterized by dis- continuous distribution patterns throughout the Mediterranean basin and by the abundan- ce of relict floristic elements ). ...

Recent geological studies demonstrated that most of Sicily was still under water during lower Pliocene, with the exception of the NE and the SE corners of the island (Peloritani Mts and Hyblaean Plateau, respectively). This geological evidence, so far not considered sufficiently by the scholars of the Sicilian flora, poses many still open questions on how and where many ancient lineages and Palaeogene relicts, currently found on the island, managed to survive. Purpose of this paper is to review the potential significance of isolation and ecological differentiation for the local floristic diversity and the evolution of narrow endemism in the Sicilian flora. In particular, the following drivers of Sicilian floristic patterns are considered: geographical segregation and age of the Sicilian terrains; climate variability and heterogenei-ty; geological patchiness; human influence on habitat fragmentation.

Grasslands differ in many types depending on the diversity of climatic conditions and substrates. Due to the great wealth of species found in semi-natural grasslands, they conserve an essential part of the biodiversity of the European Union (EEC 43/92), defined as habitats of community interest. Using the region of Calabria (southern Italy) as a case study, this study aims to evaluate how species assemblages and a set of indicators applied to them can be used to analyse and characterize the diversity, ecological features and conservation status of grassland habitats. Vegetation analysis was carried out using the phytosociological method, and habitat ecological characteristics were defined by Ellenberg’s ecological indicator adapted to the Italian flora. Multivariate analysis of the surveys by means of cluster analysis and Principal Components Analysis (PCA) made it possible to define eight habitat groups according to EEC Directive 43/92: 6110 Rocky or basophilous calcareous grasslands of the Alysso-Sedion albi, 6170 Alpine and subalpine calcareous grasslands, 6220*a Pseudo-steppe with grasses and annuals of the Thero-Brachypodietea dominated by a Lygeum spartum, 6220*b Pseudo-steppe with grasses and annuals of the Thero-Brachypodietea dominated by Hyparrhenia hirta, 6210* Semi-natural dry grasslands and scrub facies on calcareous substrates (Festuco-Bromometalia) (*important orchid sites), 6230* Species-rich Nardus grasslands, on siliceous substrates in mountain areas (and submountain areas, in Continental Europe), 6410 Molinia meadows on calcareous, peaty or clayey-siltladen soils (Molinion caeruleae), 6420 Mediterranean tall humid herb grasslands of the Molinio-Holoschoenion, 6430 Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels. Temperature (T) and oisture (U) are the most statistically significant ecological factors in differentiating different habitat types. Analysis of diversity, assessed through Shannon and Evenness indices, showed that it is strongly correlated with habitat diversity as soil moisture increases. The study of ecological characteristics, correlated with biodiversity indices, helps to characterize grassland habitats, providing guidance for the implementation of active conservation policies for these habitats.

Genista anglica L. (Fabaceae) is a Western European plant, widespread from Northern Morocco to Southern Sweden, with two geographically isolated populations in Calabria (Italy). Based on morphological characters, some authors considered the southern Italian populations as two different species: Genista silana and Genista brutia. Recent phylogeographical studies reveal that the G. silana and G. brutia populations share genetic similarities with some populations of the widespread G. anglica from Northwestern of Iberian Peninsula, despite a distance of approximately 2000 km. Previously, other authors suggested anthropogenic introduction of these plants in the South of Italy, but this hypothesis has not been thoroughly investigated. To unravel the uncertain origin of the isolated Italian populations, we conducted a more detailed study about the genetic relationships between southern Italian populations and Northwestern of Iberian Peninsula populations of G. anglica s.l., using plastid DNA sequences. Our results show identical and similar haplotypes in some of the populations of the Northwestern of Iberian Peninsula and the Italian populations, which supports the hypothesis of a recent anthropogenic introduction.

The widespread Senecio squalidus L. (Compositae: Senecioneae: Senecioninae), a diploid hybrid species with strong self‐incompatibility, that originated in the British Isles within the last 300 years, is described and illustrated. The origins of this species are briefly outlined. The history of the spread of this plant in the British Isles, and the presence of several natural hybrids is commented on. Senecio squalidus can be separated from other species, and hybrids, by allozyme differences. The species synonymy is thus minimal as it originated in the British Isles. Its morphological recognition encompasses a broader concept within Europe, including the hybrid swarm, between S. aethnensis and S. chrysanthemifolia, on Mount Etna, Sicily, where British material was originally derived. Both narrow concept and broad concept synonymy are provided, including full protologue citations and distribution of type material when known.

In this paper a survey on the garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Alta Murgia National Park is presented. These communities were compared with those of the Ionian Arc ravines. Syntaxonomic, structural, chor-ological and ecological analyses were performed in order to achieve a proper classification of this vegetation. A new association is here described, the Rhamno saxatilis-Saturejetum montanae, with two new subassociations, typicum and fumanetosum procumbentis. It is a garrigue vegetation dominated by Satureja montana subsp. montana occurring in the Murgian area, in sites characterized by rocky and stony soils and by a Mediterranean Pluviseasonal oceanic weak semicontinental phytoclimate, with thermotype upper me-so-Mediterranean and ombrotype lower subhumid, and is here framed in the Cytiso spinescentis-Saturejion montanae alliance (order Cisto cretici-Ericetalia manipuliflorae, class Cisto cretici-Micromerietea julianae). The results contribute to add a further piece to the knowledge of the natural plant landscape of the territory of the Alta Murgia National Park.

The results of a phytosociological investigation regarding the orophilous cushion-like vegetation occurring in the top of the high mountains of central-southern Greece and in some Ionian (Lefkas, Cephalonia) and Aegean Islands (Euboea, Samos, Lesvos, Chios and Thassos) are provided. Based on 680 phytosociological relevès (460 unpublished and 220 from literature), a new syntaxonomical arrangement is proposed with the description of a new class, including two new orders, eight new alliances, and several associations (many of them new). Compared to the previous hierarchical framework usually followed in the literature, this study provides a more realistic and clear phytosociological characterization of this peculiar and archaic vegetation type, which is exclusive to the high mountains of the north-eastern Mediterranean. The new arrangement is mainly based on the phytogeographical role of the orophytes featuring this very specialized vegetation, which is essentially represented by endemics or rare species belonging to the ancient Mediterranean Tertiary flora. In addition, taxonomic research on the orophilous flora occurring in these plant communities allowed to identify six species new to science (i.e., Astragalus corinthiacus, Allium cremnophilum, A. cylleneum, A. orosamium, A. karvounis, and A. lefkadensis) and a new subspecies (i.e., Allium hirtovaginatum subsp. samium), and two new combinations (i.e., Astragalus rumelicus subsp. euboicus and subsp. taygeticus) are proposed.

Orophilous plant communities of the Pino-Juniperetea class, occurring in the Central and Eastern Mediterranean area, are examined. This vegetation is characterized by the dominance of trees and shrubs, mostly represented by conifers belonging to the genera Juniperus, Abies and Pinus. These communities are nowadays relegated to the supra- and oromediterranean belt, and show a fragmentary distribution, which is an evident proof of their relict connotation. The comparison among these communities, based on original and literature data, has highlighted a remarkable floristic and structural homogeneity, together with a series of geographical vicariances. From the phytosociological point of view, this justifies the arrangement of the aforesaid communities in the class Pino-Juniperetea RIVAS-MARTÍNEZ 1964, whose range is therefore extended to the whole Mediterranean basin. In the Central and Eastern Mediterranean area, the class is represented by the order Juniperetalia hemisphaericae, which comprises two new alliances: Berberidion aetnensis, restricted to the Central Mediterranean area, and Berberido creticae-Juniperion foetidissimae, distributed in the Eastern Mediterranean area. Both of them have been on its turn split up in some suballiances, to emphasize the floristic autonomy of some well-defined phytogeographical districts. The identified associations, many of them new to science, are examined from the nomenclatural, floristical, ecological, structural and chorological point of view. New groups described pp. 265 ff.
