Introduction
Ficus is a large pantropical genus divided by Corner (1959a, 1959b, 1959c, and 1959d)
into four subgenera, two of which, Ficus subgen. Ficus and Ficus subgen. Urostigma are
well represented in Australia. The two remaining subgenera, Ficus subgen.
Pharmacosycea and Ficus subgen. Sycomorus are each represented by only one species,
F. albipida (Miq.) King and F. racemosa L. respectively. The taxa associated with the Ficus
subgen. Ficus are commonly referred to in Australia as sandpaper figs while the
members of the Ficus subgen. Urostigma are called stranglers or banyans. Each
subgenus is further divided into sections, series and subseries. In a modification of the
classification by Corner (op. cit.), Ramirez (1977a) rearranged the infrageneric
classification to better reflect the wasp specificity and morphology, and the pollination
ecology, morphology and physiology of the figs. In this classification Ramirez (1977a)
expanded Ficus subg. Sycomorus to include among others, the Ficus sections
Adenosperma and Neomorphe, each with representatives in Australia. Similarly, Berg
(1989) discussed the validity of Corner’s classification and proposed two groups
within Ficus based on morphological and functional traits connected with the
pollination ecology of the figs. In the classification of Berg (1989), two main groups
were recognised, a monoecious group consisting of the Ficus subgenera Pharmacosycea
and Urostigma, and a mainly (gyno)dioecious group consisting of the subgenera Ficus
and Sycomorus. Weiblen (2000) provided phylogenetic insights into Ficus classification
based on ITS sequences and morphology agreeing in part with Ramirez (1977a) and
125
Berg (1989). Despite the fact that infrageneric rearrangements have been proposed
subsequent to Corner (op. cit.), the monophyly of Urostigma sect. Malvanthera has been
maintained by Weiblen (2000).
Ficus has previously been treated in the Flora of Australia (Chew 1989) and was
considered to consist of 41 species. Since the Flora of Australia treatment various taxa
in the Urostigma sect. Malvanthera as well as their associated pollinator wasps have
been revised (Dixon 2001a; Dixon 2001b; Dixon 2001c; Dixon et al. 2001; Lopez-
Vaamonde et al. 2002). In addition, the species Ficus subnervosa Corner, previously
considered to be endemic to Papua New Guinea, has been found on Cape York
Peninsula, such that the key to Ficus by Chew (1989) may prove unworkable. This
work finalises the taxonomic account of the Australian taxa in the Urostigma sect.
Malvanthera providing a better understanding of the relationships between the fig taxa
and their pollinator wasp(s) species.
Methods
This revision of the Australian Urostigma sect. Malvanthera is based on the
examination of 1638 herbarium collections from AD, BM, BRI, CANB, DNA, FI, G,
JCT, K, L, LAE, MANCH, MEL, NSW, PERTH, QRS, SING, and U. I have seen and
collected all Australian species including their pollinator wasps. These specimens are
at JCT and DNA.
Taxonomic History
Fig species occurring in the Ficus subgen. Urostigma can be distinguished primarily by
their habit. This subgenus is perhaps the easiest of the four subgenera to recognise for
this is the banyan or strangling group of Ficus (Ramirez, 1977b). The epiphytic and
lithophytic habit of the species in this subgenus, commonly produce aerial,
adventitious, or creeping root systems. In addition, the wall of the syconium has an
inner and outer layer of scleritic cells. Corner (1959a) established the Urostigma sect.
Malvanthera, based on the following characters: an ostiole with two or three lobes with
inflexed bracts; syconia with two or three basal bracts; reniform unilocular anthers
with crescentic or transverse dehiscence; ovaries that are attached by their base to the
wall of the syconium, or embedded in the wall of the syconium; a red spot at the apex
or the base of the ovary; and a stigma that is either simple or bifid. The section was
further subdivided into two series:
1. Malvanthera ser. Malvanthereae: with reniform anthers that dehisce crescentically,
containing four subseries. Members of this series are wide-spread, being distributed
throughout Australasia and eastern Malaysia (Corner 1965).
(i) Malvanthereae subser. Malvanthereae: with 2 (3?) large caducous basal bracts;
pedunculate syconia; ovaries that are partially immersed in the wall of the syconium.
The taxa included are: F. macrophylla Desf. ex Pers., F. glandifera Summerh.,
F. watkinsiana F.M. Bailey, F. baileyana Domin, and F. rhizophoriphylla King.
(ii) Malvanthereae subser. Platypodeae: with 2 or 3 large caducous basal bracts;
pedunculate or sessile syconia; ovaries that are attached by their base to the wall of
126 Telopea 10(1): 2003
the syconium. The taxa included are: F. platypoda (Miq.) A.Cunn. ex Miq., F.
leucotricha (Miq.) Miq., F. obliqua G. Forst., F. subpuberula Corner, F. destruens F. Muell.
ex C. T. White, and F. rubiginosa Desf. ex Vent.
(iii) Malvanthereae subser. Hesperidiiformes: with 3 small persistent basal bracts. The
taxa included are F. hesperidiiformis King, F. augusta Corner, F. xylosycia Diels,
F. mafuluensis Summerh., F. heteromeka Corner, F. pleurocarpa F. Muell., and F. crassipes
F. M. Bailey.
(iv) Malvanthereae subser. Eubracteatae: with 3 large persistent basal bracts; pedunculate
or sessile syconia; ovaries that are attached by their base to the wall of the syconium.
Represented by one species, Ficus triradiata Corner.
2. Malvanthera ser. Cyclanthereae: with depressed globose anthers that dehisce
transversely; ovaries that are partially immersed in the wall of the syconium.
Represented by one species, Ficus sterrocarpa Diels which is restricted to eastern New
Guinea (Corner 1965).
Difficulties with the infrasectional classification
There are approximately equal numbers of species in three of the four subseries, the
exception being Ficus triradiata which is the sole member of Malvanthereae subser.
Eubracteateae. It is the only species with large persistent basal bracts. The three
remaining subseries, the subser. Malvanthereae, subser. Hesperidiiformes, and subser.
Platypodeae were defined rather loosely by persistence and size of the basal bracts.
Thus it was easy to distinguish Malvanthereae subser. Hesperidiiformes, with small
inconspicuous persistent basal bracts, from Malvanthereae subser. Malvanthereae and
Malvanthereae subser. Platypodeae which have relatively larger caducous basal bracts.
However, distinguishing the latter two subseries from each another is much more
difficult. The only difference was whether the ovaries were attached by their base to
the wall of the syconium, or were partially imbedded in the syconium wall (Corner
1959a). Also Corner (1965) may have later doubted the validity of his classification as
he included F. crassipes and F. pleurocarpa in the key to the subser. Malvanthereae as well
as the subser. Hesperidiiformes. A new infrasectional classification is proposed.
There are 14 Australian species recognised in the Urostigma sect. Malvanthera. A
comparison of the classification of Chew (1989) and this research is presented in Table
1. Ficus lilliputiana was treated by Dixon (2001a), F. macrophylla (Dixon 2001b), F. obliqua
and F. rubiginosa (Dixon et al. 2001), and F. atricha, F. cerasicarpa, F. platypoda and
F. brachypoda (Dixon 2001c). Species descriptions are presented for the following taxa:
F. crassipes, F. destruens, F. pleurocarpa, F. subpuberula, F. triradiata, and F. watkinsiana. For
each species there is a discussion on etymology, nomenclature where necessary,
distribution and ecology, and conservation status. Distributional ranges are provided
for each taxon. In species where infraspecific taxa are described, a key to their
identification is given. Plates and illustrations found in other texts are listed so that
these texts can be updated with the correct nomenclature where necessary. The
pollinator wasp of each Ficus species is also given. The author abbreviations for the
plant taxa follow Brummitt and Powell (1992).

Morphology
Basal bract form: The developing syconia are axillary and occur in pairs. At its
junction with the peduncle, the syconium is subtended by either two or three basal
bracts. These bracts are valvate or imbricate, either large and completely enclosing the
developing syconium, or reduced and never enclosing the developing syconium. For
the majority of the species these bracts are caducous; however, in two species they
remain persistent for the life of the fig. In previous taxonomic treatments on this
section, the basal bract number was considered to be fixed for each species and was
used as an important character in delimiting some species, especially F. obliqua and
F. platypoda with supposedly two and three basal bracts respectively (Corner 1965).
I have found that the basal bract number is variable within some species in this section
of Ficus and is therefore not a reliable character for species delimitation.
Basal veins of lamina: There may or may not be distinct lateral veins present at the
base of the lamina. These veins diverge from the midvein at a different angle from the
remainder of the lateral veins and were measured separately. The measurement taken
was the displacement from the midrib. Basal veins are very distinct in the rainforest
species, but indistinct in the deciduous vine thicket species.
Number of lateral veins: Both the major and minor lateral veins diverging from the
midvein were counted. I could never consistently agree with the number of lateral
veins recorded by Corner in his descriptions. Thus for consistency I counted both the
major and minor lateral veins diverging off the midrib. The major lateral veins curve
inside the margin and join with the next major vein. The minor lateral veins are those
between two major veins.
128 Telopea 10(1): 2003
Habit: The Urostigma sect. Malvanthera contains species that are hemi-epiphytic
trees, erect free-standing trees or shrubs, lithophytic trees or shrubs, or lithophytic
prostrate shrubs.
Intercostal region of lamina: The intercostal region between the tertiary veins on the
abaxial surface of the lamina can either be sunken to form areolae as is found in
F. cerasicarpa and F. platypoda, or flat as is found in the remainder of the species in the
Urostigma sect. Malvanthera.

Biogeography: There appear to be two diverging groups in this series, a hemi-epiphytic
rainforest group represented by F. destruens, F. watkinsiana, and F. macrophylla, and a
lithophytic deciduous vine thicket group represented by F. platypoda, F. brachypoda,
F. cerasicarpa, F. atricha, and F. lilliputiana. The later group also shows strong
biogeographical support with all the taxa found in deciduous vine thickets on the
sandstone escarpments of central and north-western Australia. Ficus rubiginosa and F.
obliqua are not obligate hemi-epiphytes, neither are they restricted to rainforest. They can
also occur as lithophytes and hemi-epiphytes in deciduous vine thickets. Ficus destruens
is also not restricted to the rainforest. It is often found as a hemi-epiphyte in ecotonal
areas adjacent to rainforest. These taxa suggest the occurrence of transition species
between the hemi-epiphytic taxa and the lithophytic taxa and thus preclude the
recognition of two subseries within the series.

Australia has high levels of endemism in the Urostigma sect. Malvanthera (Corner

the section.
Malvanthera ser. Hesperidiiformes
This series consists of taxa with valvate basal bracts. All the species in this series are
rainforest hemi-epiphytes from Australia, New Guinea, and the New Britain,
Solomon, and New Hebrides island groups. Three species, F. triradiata, F. crassipes, and
F. pleurocarpa, are endemic to the closed forests of the Australian wet tropics.
Pollinator Wasps
The group of wasps that pollinate the florets of the numerous Ficus species belong to
the Hymenopteran subfamily Agaoninae. At the sectional level of Ficus, with all but a
few exceptions, Wiebes (1994) was able to show that related Ficus species have related
genera of pollinator wasps. The Ficus species in the Urostigma sect. Malvanthera are
pollinated by wasps of the genus Pleistodontes Saunders (Wiebes 1994). The Indo-
Australian fig wasps have recently been treated by Wiebes (1994) who provided keys
and descriptions of the wasp species presently known. Within the Urostigma sect.
Malvanthera Wiebes (1994) recorded the same species of pollinator wasp from different
species of Ficus and as such provided evidence for exceptions to the 1: 1 rule for fig
wasp/host specificity. With the revision of the Australian Urostigma sect. Malvanthera
and the pollinator wasp genus Pleistodontes now complete, I consider that much of the
confusion over the wasp/host specificity was generated by unsatisfactory and
incomplete taxonomies. For example, Table 3 compares the discrepancies that existed
between the classifications of Chew (1989) and Wiebes (1994) and how the taxa are
treated by this research and Lopez-Vaamonde et al. (2002).

Species descriptions
1. Ficus obliqua G.Forst. Fl. Ins. Austral. 77 (1786). A full description for this species is
presented in Dixon et al. (2001).
Pollinator wasp(s): Two pollinator wasps have been recorded by Lopez-Vaamonde
et al. (2002) for F. obliqua. They are Pleistodontes greenwoodi Grandi and Pleistodontes
xanthocephalus Vaamonde, Dixon, Cook & Rasplus.
2. Ficus pleurocarpa F.Muell., Fragm. 8: 246 (1874). Type: Johnson River, QLD, W. Hill
s.n. (holo n.v.).
According to Stafleu and Cowan (1976) the type of F. pleurocarpa, being a Mueller
name, should be at MEL; however, efforts to locate it at MEL have failed. Attempts to
locate the type at K or the British Museum (BM) were unsuccessful. There is a
specimen of F. pleurocarpa with a Mueller label at K, it has the correct locality details,
but it lacks the collector’s name of ‘W. Hill’ as cited by Mueller (1874) in the
protologue, which would authenticate this specimen as the type.

Etymology: The epithet pleurocarpa is derived from the Greek prefix pleuro- meaning
ribbed, and the Greek adjectival suffix –carpus, and refers to the syconia that have 5–10
ribs running from the base to the tip of the syconium.
Distribution and Ecology: Ficus pleurocarpa is a hemi-epiphytic species restricted to
the lowland and upland wet tropic rainforests of north-east Queensland (Fig. 1) with
an altitudinal range from near sea level to 1000m (Hyland & Whiffin 1993). Ficus
pleurocarpa is endemic to Australia.
Notes: Commonly referred to as Banana Fig, it is easily identified by its large orange to
red cylindrical syconia that bear up to 10 ribs running from base to tip. The ostiole bears
four, sometimes indistinct, lobes often forming a crown at the apex of the syconium.
Conservation Status: Ficus pleurocarpa is well conserved in national parks and
state forests throughout its distributional range, therefore no conservation code
is recommended.

Pollinator Wasp(s): Two pollinator wasps have been recorded by Lopez-Vaamonde et
al. (2002) for F. pleurocarpa. They are Pleistodontes regalis Grandi and Pleistodontes
deuterus Vaamonde, Dixon, Cook & Rasplus. This association constitutes one of the
few examples where two pollinator species have been reared from the same syconium
of a Ficus species.

Etymology: The epithet crassipes is derived from the Latin adjective crassus meaning
thick, and refers to the thick peduncle on the syconia of this species (Meston 1889).
Distribution and Ecology: Ficus crassipes is a hemi-epiphytic species restricted to
upland areas of the wet tropic rainforests of north-east Queensland (Fig. 3). It has an
altitudinal range of 650–1000 m (Hyland & Whiffin 1993) and is endemic to Australia.
Notes: Commonly referred to as Round Leaf Banana Fig, F. crassipes is sometimes
confused with F. pleurocarpa, it is easily identified by its large brownish cylindrical
syconia, the very small persistent papery basal bracts, and the probosciform
triradiate ostiole.
Conservation Status: Although much of the rainforest of the Atherton Tablelands has
been cleared, F. crassipes is still commonly encountered and is well-conserved in state
forests throughout its distributional range. Therefore no conservation code is
recommended.

Pollinator Wasp(s): Two pollinator wasps have been recorded by Lopez-Vaamonde et al.
(2002) for F. crassipes. They are Pleistodontes nitens Grandi and Pleistodontes addicotti
Wiebes. Together with the pollinators of F. pleurocarpa this is one of the few instances in
which two pollinator species have been reared from the same syconium of a Ficus
species. Wiebes (1994) cited F. pleurocarpa as the host of P. nitens; however Vaamonde et
al. (2002) stated that previous treatments had misinterpreted P. nitens.

Etymology: The species epithet is Latin for destroy, and refers to the ability of this
species to destroy its host. Ficus destruens is a strangler fig eventually killing its host
thus securing its place in the canopy of the rainforest.
Distribution and Ecology: Ficus destruens is found mainly in upland areas of the wet
tropic rainforests of north-east Queensland at altitudes between 350 and 1000 m
(Hyland & Whiffin 1993). However, I have observed it growing in the tropical lowland
rainforests at Broadwater State Forest, north of Ingham. It extends from the Atherton
Tablelands, south to Eungella Range west of Mackay (Fig. 5). It is a hemi-epiphytic
species that is occasionally found as a strangler on Eucalyptus grandis W.Hill ex Maiden
in the wet sclerophyll forests of Eungella Range (Chew 1989), and on other eucalypt
species around Cairns (White 1933). Ficus destruens is endemic to Australia.
140 Telopea 10(1): 2003
Notes: Ficus destruens is easily identified in the rainforest by its bilabiate syconia and
the somewhat dense covering of weak, often tomentose, ferruginous hairs on the
abaxial surface of the leaf. The older leaves may appear glabrous at first glance but on
closer inspection some ferruginous hairs can be found at the base of the lamina.

Etymology: Corner (1959a) did not give a derivation for the species epithet. However,
it is most likely in reference to the three large persistent basal bracts found on the
syconia of this species.
Nomenclatural Notes: In his comments concerning the infraspecific taxa of this
species, Chew (1989) suggested that the two varieties, F. triradiata var. triradiata and
F. triradiata var. sessilicarpa, may represent different developmental stages of the same
taxon. It has become evident during the studies on the Urostigma sect. Malvanthera
that the peduncle of many species is often quite variable in length and is not a good
taxonomic character. The figs present on the type specimen of F. triradiata var.
sessilicarpa do appear sessile; however, they are much smaller than the mature figs of
this species. The size of the syconia on the type specimen of F. triradiata var.
sessilicarpa (12–15 mm long, 11–13 mm in diameter), are outside the range of
dimensions for the mature syconia of this species (21–26 mm long, 15–26 mm in
diameter). Thus I have concluded that F. triradiata var. sessilicarpa was described from
a specimen with immature syconia and have accordingly reduced it to synonymy
under the type species.

Fig. 6. The holotype of Ficus triradiata Corner.
Distribution and Ecology: Ficus triradiata is found in lowland and upland wet tropical
rainforest of north-east Queensland (Fig. 7), at an altitudinal range from near sea level
to 1300 m (Hyland and Whiffin, 1993). This species is hemi-epiphytic and is endemic
to Australia.
Notes: It is an attractive species with peach to apricot coloured figs and is commonly
referred to as Red Stipule Fig. The common name is a misnomer as the stipules are
translucent white when mature. The stipules are only red in colour when the growing
point is inactive. It is easily identified by the syconia always having three large
persistent basal bracts.
Conservation Status: Ficus triradiata has been relatively poorly collected and was
considered poorly known (Staff, Queensland Herbarium, 1994) and given a
conservation coding of 2K by Briggs and Leigh (1996). However, it is commonly
encountered throughout its limited distributional range between Mount Molloy and
Cooktown. During a field trip to the Windsor Tablelands in December 1996, 103
individuals were encountered along a 24.6 km section of logging road. Twenty-one
individuals were encountered along a three kilometre section of road on Mount Lewis.
Ficus triradiata also occurs in the rainforests of Cape Tribulation and is adequately
conserved in forestry reserves across its entire range. No conservation code is
necessary at this present time.

Fig. 8. The lectotype of Ficus watkinsiana F.M.Bailey AQ66925 (BRI). The specimen consists of two
sheets of which only sheet one is shown.
Etymology: Named in honour of George Watkins who was a collector of Queensland
plants (Bailey, 1891).
Distribution and Ecology: Ficus watkinsiana is a hemi-epiphytic species found in
upland rainforest. This species occurs in two disjunct populations, one in north-
eastern Queensland between Cairns and Townsville, and the other in south-eastern
Queensland and north-eastern New South Wales (Fig. 9). Ficus watkinsiana is endemic
to Australia.
Notes: Commonly referred to as Watkin’s Fig or Green-leaved Moreton Bay Fig,
F. watkinsiana is easily recognised in the rainforest. At first glance the leaves resemble
those of F. pleurocarpa, however, they lack the tomentose to felted covering of
ferruginous hairs and the leaves are on average smaller in size being 51–217 mm long,
26–97 mm wide in F. watkinsiana compared to 150–256 mm long, 49–100 mm wide in
F. pleurocarpa. The syconia of F. watkinsiana are dark purple to black when mature and
lack ribs compared to those of F. pleurocarpa which have up to 10 longitudinal ribs and
are orange-red when mature.
Conservation Status: Ficus watkinsiana is adequately conserved throughout its
distributional range and therefore no conservation code is recommended.

Pollinator Wasp: Lopez-Vaamonde et al. (2002) reported that Ficus cerasicarpa is
associated with two species of pollinator wasp, Pleistodontes macrocainus Vaamonde,
Dixon, Cook & Rasplus and Pleistodontes athysanus Vaamonde, Dixon, Cook &
Rasplus. Pleistodontes athysanus is mainly recorded from F. brachypoda; however, two
specimens were also identified from a collection of Pleistodontes macrocainus reared
from F. cerasicarpa collected at Mount Isa (Dixon & Champion, PhD 405), see Dixon

Etymology: Corner (1959a) did not provide a derivation for the epithet. However, it
most likely applies to the leaves of F. subpuberula being ‘almost pubescent’.
Distribution and Ecology: Ficus subpuberula is a lithophytic species restricted to
sandstone gorges and rock crevices. It occurs from Lawn Hill National Park, on the
extreme western edge of Queensland west across the Top End of the Northern
Territory to the Kimberley area of Western Australia (Fig. 11). It is endemic to Australia
and has previously not been recorded from Queensland.
Notes: Ficus subpuberula is easily recognised. The foliage is often sparse, pendulous,
and a dull grey green colour. The figs are a lemon-yellow colour when mature.

Conservation Status: Ficus subpuberula is adequately conserved in national parks of
Queensland, the Northern Territory, and Western Australia, therefore no conservation
coding is recommended.

Acknowledgments
I am indebted to many people. For as much as this research is my own work, without
the help and support of friends and colleagues this work would not have been
possible. Thanks to Craig Burgess for the preparation of the distribution maps; Rita
Bisley at Document Supply, James Cook University for locating the Ficus protologs,
some of which required expert detective work to find. For companionship in the field
I am especially thankful to Irene Champion and Brad Mayger. I wish to express my
gratitude for the financial support provided by the Rainforest CRC. The following
herbaria AD, BM, BRI, CANB, DNA, FI, G, JCT, K, LAE, MANCH, MEL, NSW,
PERTH, QRS, SING, and U kindly provided specimens on loan or bench space during
my visits. I thank the Directors and Staff of these institutions, for without access to
these valuable collections this research would not have been possible. I would also like
to thank the Australian Botanical Liaison Officer (ABLO), Ken Hill, who examined and
photographed many type specimens at K and during his visits to other overseas
herbaria. Without data from these important specimens many of the names could not
have been applied correctly. Finally I wish to express my thanks to Assoc. Prof. Betsy
Jackes and Dr Leone Bielig, their guidance, encouragement, support, and patience has
been constant.

... Here, we use two such approaches to infer the population divergence history of Pleistodontes nigriventris, a wasp that is the only pollinator of an endemic fig species (Ficus watkinsiana) found in two widely separated blocks of rainforest along the east coast of Australia (see below) (Dixon, 2003;Lopez-Vaamonde, Dixon, Cook, & Rasplus, 2002). Our overall objective is to infer the extent and direction of fig wasp gene flow between these two populations, using WGD for just two individuals per population. ...
... (Cook & Rasplus, 2003;Harrison, 2005), and fig fruits and their insect inhabitants are important model systems in the study of community assembly and coevolution (Cook & Rasplus, 2003;Segar, Dunn, Darwell, & Cook, 2014). Our target species Pleistodontes nigriventris is the specialist pollinating wasp of Ficus watkinsiana (Lopez-Vaamonde et al., 2002;Male & Roberts, 2005;Rønsted, Weiblen, Savolainen, & Cook, 2008 (Dixon, 2003). While the existence of intervening F. watkinsiana trees and associated P. nigriventris cannot be categorically excluded, no populations are known; the demographic history of P. nigriventris can thus be modelled in terms of pairwise population F I G U R E 1 The IM (divergence with continuous migration) and ADM (divergence with instantaneous admixture) models of population divergence with gene flow, showing the demographic parameters estimated in our blockwise method analyses. ...
... The rainforest areas occupied by F. watkinsiana are currently separated by two major dryland corridors ( Figure 2): the Burdekin Gap, located between Mackay and Townsville, is the largest dry land corridor on the east coast, and the St. Lawrence Gap is a smaller lowland dry corridor located 350km further south (Bryant & Krosch, 2016;Weber et al., 2014). While the formation and stability of these dryland corridors through time is incompletely characterized (Bryant & Krosch, 2016), both have been implicated in restricting dispersal and driving population divergence in rainforest plants (Burke et al., 2013), including F. watkinsiana (Dixon, 2003;Haine & Cook, 2005), and animals (e.g. Baker et al., 2008;Brown, Cooksley, Carthew, & Cooper, 2006;Bryant & Fuller, 2014;Bryant & Krosch, 2016;Dolman & Moritz, 2006;MacQueen, Seddon, & Goldizen, 2012;Nicholls & Austin, 2005;Pope, Storch, Adams, Moritz, & Gordon, 2001;Rix & Harvey, 2012;Schäuble & Moritz, 2001). ...

Population divergence and gene flow are key processes in evolution and ecology. Model‐based analysis of genome‐wide datasets allows discrimination between alternative scenarios for these processes even in non‐model taxa. We used two complementary approaches (one based on the blockwise site frequency spectrum (bSFS), the second on the Pairwise Sequentially Markovian Coalescent (PSMC)) to infer the divergence history of a fig wasp, Pleistodontes nigriventris. Pleistodontes nigriventris and its fig tree mutualist Ficus watkinsiana are restricted to rain forest patches along the eastern coast of Australia, and are separated into northern and southern populations by two dry forest corridors (the Burdekin and St. Lawrence Gaps). We generated whole genome sequence data for two haploid males per population and used the bSFS approach to infer the timing of divergence between northern and southern populations of P. nigriventris, and to discriminate between alternative isolation with migration (IM) and instantaneous admixture (ADM) models of post divergence gene flow. Pleistodontes nigriventris has low genetic diversity (π = 0.0008), to our knowledge one of the lowest estimates reported for a sexually reproducing arthropod. We find strongest support for an ADM model in which the two populations diverged ca. 196kya in the late Pleistocene, with almost 25% of northern lineages introduced from the south during an admixture event ca. 57kya. This divergence history is highly concordant with individual population demographies inferred from each pair of haploid males using PSMC. Our analysis illustrates the inferences possible with genome‐level data for small population samples of tiny, non‐model organisms and adds to a growing body of knowledge on the population structure of Australian rain forest taxa.
... More recent papers have only dealt with select species groups. The rock figs of northern and central Australia (Ficus section Malvanthera Corner) have been, and continue to be, difficult for taxonomists to circumscribe (Chew 1989;Henderson 1993;Dixon 1999Dixon , 2001aDixon , 2002Dixon , 2003Dixon et al. 2001). Many species occur in remote, poorly botanically explored locations across the rocky ranges of northern and inland Australia, are poorly represented in herbarium collections, and commonly display considerable morphological variation. ...
... This is also reflected by the wide distribution of the species, from western Queensland, Northern Territory, northern Western Australia and northern South Australia. Dixon (2003) later also included collections from the Lesser Sunda Islands and Timor within this species. Thus defined, Ficus brachypoda is the most widely distributed of all Australian figs ( Fig. 2A) and sympatric with five other figs in section Malvanthera Corner; F. atricha D.J. Dixon (2001a) (Fig. 2B), F. cerasicarpa D.J. Dixon (2001a), F. lilliputiana D.J. Dixon (2001b), F. platypoda (Miq.) ...

A new species of lithophytic fig, Ficus desertorum B.C.Wilde & R.L.Barrett, endemic to arid Central Australia, is described and illustrated. It is distinguished from other species in Ficus section Malvanthera Corner by having stiff lanceolate, dark green, discolorous leaves; many parallel, often obscure lateral veins; petioles that are continuous with the midrib; with minute, usually white hairs and non- or slightly sunken intercostal regions on the lower surface. Previously included under broad concepts of either Ficus platypoda (Miq.) Miq. or Ficus brachypoda (Miq.) Miq., this species has a scattered distribution throughout Central Australia on rocky outcrops, jump-ups (mesas) and around waterholes. This culturally significant plant, colloquially referred to as the desert fig, grows on elevated landscapes in central Australia, including Uluru (Ayers Rock), Kata Tjuta (The Olgas) and Karlu Karlu (Devils Marbles), three of Central Australia’s best-known natural landmarks. Evidence is provided to show these plants are geographically and morphologically distinct from Ficus brachypoda, justifying the recognition of F. desertorum as a new species. Taxonomic issues with F. brachypoda and F. atricha D.J.Dixon are also discussed. Lectotypes are selected for Urostigma platypodum forma glabrior Miq. and Ficus platypoda var. minor Benth.
... For taxonomic identification of pollinator wasps (i.e., Agaonidae) and non-pollinator wasps (e.g., Pteromalidae), we followed Ishii (1934), Wiebes (1964), Berg and Wiebes (1992), Wiebes (1994), van Noort and Rasplus (1997) To crosscheck the identity of wasps using new hosts, we sequenced the mitochondrial gene for cytochrome b (cytB) following the protocols described by Lopez-Vaamonde et al. (2001). Dichotomous keys for identifying figs included Corner (1965), Berg and Wiebes (1992), and Dixon (2003). In the case of multiple individuals of the same wild-growing fig species, we corroborated our taxonomic identification by sequencing the nuclear ribosomal internal transcribed spacer region (ITS1, 5.8S, and ITS2) according to methods outlined by Weiblen (2000) and Rønsted et al. (2008). ...
... On the North Island of New Zealand, non-native figs include F. rubiginosa and F. obliqua G.Forst. (Gardner and Early, 1996), both of which are in subsection Platypodeae and have overlapping native ranges in Australia (Dixon, 2003;Rønsted et al., 2008), although only the former is naturalized due to the introduction of P. imperialis. Gardner and Early (1996) noted P. imperialis in many syconia of F. obliqua, yet despite the absence of the normal pollinator for F. obliqua in New Zealand, P. imperialis was unable to pollinate the ovules, no seed development took place, and the authors remarked that females were "stuck in the ostiole." ...

The reliance of each fig species on its specific pollinator wasp, and vice versa, is the archetype of both obligatory mutualism and coevolution. Pollinator sharing between host fig species is only known to occur among closely related sympatric species. On the Hawaiian island of Kauai, we gathered syconia from 23 non-native fig species, three of which contained the wasp Pleistodontes imperialis. Of the three fig species, one is the wasp’s natural host, Ficus rubiginosa, and another is its sister species, Ficus watkinsiana, which overlaps in native ranges, although researchers have not previously documented pollinator sharing. The third fig species, Ficus rubra, is distant to the others both in terms of phylogenetic relationship and native range. We found viable seeds for all three fig species, whereas species without wasps did not produce seeds. To investigate similarity between these pollinator-sharing fig species, we collected morphometric data for syconia of our study fig species. We found that fig species with and without P. imperialis significantly differ based on the orientation of their inner ostiolar bracts. These findings suggest that pollinator sharing among these three fig species may normally be impeded by pollinator competition in the case of F. watkinsiana, and by geographic distance in the case of F. rubra. This work therefore demonstrates that coevolution depends on interactions within native species assemblages, and that mutualisms can be disrupted in new non-native communities.

Ficus pellucidopunctata subsp. obpyriformis is described and illustrated from the North Andaman Island of India. The new taxon resembles Ficus pellucidopunctata in punctale leaf, leaf shape and venation, but differs with the typical species by its longer and obpyriform fig, (verses ellipsoid); scaly minute (ca. 2 mm) basal bracts that do not cover the base of the fig (verses larger (ca. 6 mm) basal bracts that cover the base of the fig); fig orange to dark brown (verses green to yellow); branches terete (verses. angular). Ficus pellucidopunctata subsp. obpyriformis seeds germinated and saplings were planted and are growing in the Dharmavana Nature Ark (DNA), Bhongir, Telangana as part of the DNA ex-situ conservation programme.
... The genus of Ficus is subjected to earlier systematic studies, such as systematics of subgenus Urostigma sect. Malvanthera (Dixon 1999), in addition, he conducted a systematic revision of Ficus species (subgenus Urostigma, section Malventhera) in Australia (Dixon, 2003). Mubo et al. (2004) made a morphometric analysis of this genus; Furthermore, van Noort et al. (2007) recorded two species of Ficus in Mozambique, while Ogunkunle and Oladele (2008) studied the leaf epidermis of the 20 Nigerian Ficus species; however; Chaudhary et al. (2012) provided a synopsis of the 115 taxa of genus Ficus in India, while, Fatihah et al. (2012) studied the correlation between the morphology and the genetic analysis of seven varieties of Ficus deltoidea from Malaysia, whereas, Jangam et al.

The taxonomy of Ficus L., 1753 species is confusing because of the intense morphological variability and the ambiguity of the taxa. This study handled 36 macro-morphological characteristics to clarify the taxonomic identity of the taxa. The study revealed that Ficus is represented in the Egyptian gardens with forty-one taxa; 33 species, 4 subspecies and 4 varieties, and classified into five subgenera: Ficus Corner, 1960; Terega Raf., 1838; Sycomorus Raf., 1838; Synoecia (Miq.) Miq., 1867, and Spherosuke Raf.,1838; out of them seven were misidentified. Amongst, four new Ficus taxa were recently introduced to Egypt namely: F. lingua subsp. lingua Warb. ex De Wild. & T. Durand, 1901; F. pumila L., 1753; F. rumphii Blume, 1825, and F. sur Forssk., 1775. The application of the multivariate analyses in plant systematics namely the two-way clustering analysis and the principal component analysis revealed that the qualitative characters as the presence or absence of lateral peduncular or ostiolar bracts and the leaf margin delimit the differentiation of subgenera within genus Ficus. Whereas the qualitative characters of the leaf as leaf arrangement, lamina shape, length, ratio of length to width, base, apex, number of lateral veins, stipules and figs either pedunculate or sessile, shape, and width are significantly separating the species within the different sections. Seven different identification keys of the studied taxa based on the examined characters are provided. In addition, a diagrammatic key for all the studied taxa is given.

Ficus L., commonly known as Fig, is a member of the family Moraceae (mulberry family) comprises 37 genera and approximately 1,100 species distributed in diverse ecosystems, especially in tropical and temperate regions of the world. The Ficus genus stands out as a keystone resource provider in many tropical forests, which is probably because of continuous non-seasonal fruiting in many species. It is one of the largest genera in the angiosperms about 750 species. The present study was carried out in the Forest Research Institute (FRI) campus, Dehradun (Uttarakhand), India. The phytodiversity of Ficus L. and their socio-economic values worked out during the investigation, religious-spiritual attachment, food of wild animals, ethnomedicinal and timber significance. There were 16 species of Ficus L. recorded from New Forest, FRI, Dehradun based on the morphological observations of taxonomically significant characteristics. The species found in FRI New Forest Dehradun were, Ficus benjamina, F. religiosa, F. racemosa, F. rumphii, F. retusa, F. krishnae, F. elastica, F. virens, F. semicordata, F. auriculata, F. hispida, F. pumila, F. palmata, F. drupacea, F. benghalensis, F. pomifera. Out of the notified 16 species of Ficus, 11 species were trees, 3 shrubs and 2 climbers in nature. The maximum leaf size (30×27cm2) was reported in F. auriculata, followed by F. semicordata (28×10cm2), F. benghalensis (25×11cm2). However, minimum leaf size was noticed in F. benjamina (4×2cm2) and F. retusa (4×3cm2). Among, 15 species, axillary fig (fruit) arrangement was observed, while one species (F. racemosa) has stem position of fruits. The current finding is itself a pioneer study to present a glimpse of such immense species diversity of single genera from sub-valley areas and will be a milestone for future studies in conservation and management of these wild varieties.
... These host figs are all classified in subgenus Urostigma, the banyan or strangling group of Ficus, which commonly produces aerial, adventitious or creeping root systems. In addition, the walls of the sycones of this group have an inner and an outer layer of sclerotic cells (Dixon, 2003), which could potentially limit the number of nematode species able to colonise and feed on them. A recent study of the phylogeny of section Malvanthera (Rønsted et al., 2008) showed that it was monophyletic. ...

Ficophagus from collecting trips in eastern Australia, made over 15 years, are summarised and show that species of the genus occurred widely in sycones of Ficus , subgenus Urostigma , section Malvanthera . Two new species (based on morphological differences and molecular sequencing) are described: Ficophagus elizabethae sp. n. from Ficus macrophylla , F. rubiginosa and F. obliqua , and Ficophagus richardi sp. n. from Ficus obliqua ; and a morphospecies, Ficophagus Morphospecies malandicus from Ficus obliqua. Ficophagus elizabethae sp. n. is characterised by having the excretory pore (EP) opening from the level of the junction of the conus and shaft of the stylet to that of the knobs, a relatively long procorpus (1.0-2.5 times length of stylet), female tail with an obliquely truncate tail with a hyaline area and a finely to broadly rounded tip which may be mucronate; post-vulval uterine sac (PUS) ca one vulval body diam. (VBD) in length; rose-thorn-shaped spicule with distinct rostrum and prominent condylus; and genital papillae arranged as largest pair adcloacal, second pair posterior to mid-tail length, and third small pair near tail tip; and was collected from Sydney in New South Wales, to Bundaberg in Queensland (QLD). Ficophagus richardi sp. n. is characterised by having the EP opening at the level of the junction of the stylet shaft and conus, a labial cap which is raised around the opening for the stylet; procorpus 0.8-1.7 times length of the stylet, PUS <1 VBD in length, long uterus, and female tail with a V-shaped hyaline area at the bluntly rounded tip; rose-thorn-shaped spicule with a small rostrum and prominent condylus, three pairs genital papillae, first and largest on anterior cloacal lip, second at 70% of tail length measured from cloacal aperture, and third near tip, and was collected from Ban Ban Springs in the south to the Bundaberg region in the mid-north of QLD. In addition, in the absence of pertinent molecular sequences, a morphospecies is described. Ficophagus Morphospecies malandicus is characterised by having the EP opening anterior to the junction of the stylet conus and shaft, procorpus 0.9-2 times length of stylet, a short PUS usually <1 VBD long, short uterus, rose-thorn-shaped spicule with a raised condylus and prominent rostrum, and three pairs of subventral papillae on the tail (one adcloacal, one posterior to mid-tail and one near tail tip); and was collected from the Atherton Tableland, QLD. A table comparing morphological characteristics is provided to help with identification of Ficophagus nematodes from figs of the section Malvanthera in eastern Australia.

He had recorded 112 species and 47 infraspecific taxa from whole British India (7), out of which only 75 species and 16 infraspecific taxa were reported from the present geographical boundary of India (5). A great number of works had been published on the systematics of Ficus from different regions of the world (2,(8)(9)(10) which have contributed to identification, classification and nomenclature. The genus has been further classified into six subgenera, 19 sections and 27 subsections based on morphological characters and distribution pattern (2). ...

The present communication is the first report of new distributional record of Ficus altissima Blume (Moraceae) in Tripura. F. altissima was found to be an important feeding and nesting habitat for forest frugivores, since the genus is very rich in diversity and is considered as a keystone species. This also possesses huge scope to understand the mechanism of interactions especially for conservation of rich avifaunal diversity. Brief description and field photographs are presented for facilitating easy identification of the species.
... Worldwide, several strategies have been followed to resolve the taxonomical status of section Cordifoliae. The notable approaches include: morphology and geographic distribution (Dixon 2003, Berg 2004, Chantarasuwan et al. 2013, Pederneiras et al. 2018, genetic diversity using ISSR markers (Rout & Aparajita 2009), molecular sequences (Weiblen 2000, Rønsted et al. 2008b, Li et al. 2012a,b, Kusumi et al. 2012, Olivar et al. 2014, Chantarasuwan et al. 2015, Pederneiras et al. 2018, leaf and wood anatomical studies (Ogunkunle et al. 2008, Ogunkunle et al. 2014, Chantarasuwan et al. 2014, leaf epidermal studies (Klimko & Truchan 2006) and mutualism between figs and their pollinating wasps studies (Ramirez 1977, Rønsted et al. 2008a. ...

Cystoliths are microscopic calcium deposits found remarkably in some genera and is of key importance to understand its taxonomic value. Leaf samples of 19 species belonging to 7 sections of Indian Ficus were processed for anatomical studies and surface micromorphological characteristics of cystoliths. The morphology, distribution and sculpture patterns of cystolith found varying among species. Four types of basic sculpturing patterns have been observed in this study: aculeate, colliculate, verrucate, and tuberculate. The aculeate sculpturing pattern is the most common type observed in twelve species of section Cordifoliae, but further division of this pattern into three subtypes i.e. broad, moderate and reduced aculeate along with the length and width of cystoliths appendages and the mode of stalk fixation provides more informative insight into sub-sectional classification. Principal component analysis (PCA) provides a supporting evidence for earlier classification at sectional/subsectional level. Though in few cases it has not support the decision taken by molecular studies. This study suggests that cystolith micromorphological characters could be utilized in the re-classification of Ficus taxa at sub-sectional level.

Several Oriental and Australian species of Ficus have been introduced outside their native range and planted as ornamentals in urban habitats throughout the Mediterranean. This translocation of plant species has led to the introduction of host-specific insects such as their pollinating fig wasps (Hymenoptera: Agaonidae). Here, the Australian fig wasp Pleistodontes imperialis Saunders, 1882 is reported for the first time from Greece. Partial COI genes were sequenced for specimens sampled in Greece and Cyprus, and they appear to share identical haplotypes. Interestingly, this species-specific wasp not only develops in figs of its usual host, Ficus rubiginosa, but also in figs of Ficus watkinsiana, another Australian species introduced in Greece, which is pollinated by a second agaonid species (Pleistodontes nigriventris Girault, 1915) in its native range. Although no negative economic or environmental impacts have been observed yet, monitoring of alien Ficus spp. in the region is encouraged to prevent their possible establishment in natural habitats.

Ficus displays many problems fundamental to the distribution of tro-pical plants. As a natural g-enus, one of the most derived of its family, it shows that these problems refer not to the origin of the genus or of its major groups, but to the subsequent course of sectional evolution. Detailed morphological revision must, therefore, precede phytogeography. The facts, here epitomised, are based on monographic revision of the species of Asia and Australasia, and have not been called from other writings. Seed-dispersal in Ficus must be accompanied by dispersal of the pollinating wasp. It seems true, as Beccari pointed out, that the large banyans have an advantage in this respect over small trees impeded by the dense forest.Two subgenera, Pharmaeosycea and Urostigma, suggest a southern migration, but the third subgenus Ficus suggests a northern origin and dispersal. Pharmaeosycea, hitherto regarded as American, has 46 species in Asia and Australasia, and it comprises most of the fig-flora of New Caledonia (26 species in all, 20 endemic species of Pharmaeosycea). Ficus prolixa (Polynesia) seems related to sect. Americana of Urostigma. The F. elastica group (Queensland, Papua, Solomon Islands) seems related to the African sect. Bibracteata of Urostigma. The F, benghalensis group parallels the distribution of the Dipterocarpaceae, but does not occur inAfrica.

A revision of the species complexes of ‘Ficus platypoda’ and ‘Ficus leucotricha’ (Moraceae: Urostigma sect. Malvanthera Corner) is presented. A phenetic analysis of morphometric characters using clustering techniques and multidimensional scaling was used to identify the taxa in each species complex. Two species from each complex are recognised and include Ficus brachypoda (Miq.) Miq. and here described Ficus atricha D.J. Dixon from the ‘F. platypoda’ complex and F. platypoda (Miq.) A. Cunn. ex Miq. and here describedFicus cerasicarpa D.J. Dixon from the ‘F. leucotricha’ complex. Each Ficus species is pollinated by a morphologically distinct pollinator wasp. Ficus platypoda is pollinated by Pleistodontes cuneatusWiebes. Ficus cerasicarpa, F. atricha and F. brachypodaare pollinated by wasps that are new species yet to be described. The nomenclature of F. brachypoda and F. platypoda is discussed and a key to the species as well as notes and distribution maps are provided for all four species.

A revision of the Ficus obliqua—F. rubiginosa complex (Moraceae: Urostigma sect. Malvanthera Corner) is presented. A phenetic analysis of morphometric characters using clustering techniques and multidimensional scaling was used to identify the taxa in this complex. Three taxa are recognised, F. obliqua G.Forst., F. rubiginosa Desf. ex Vent. f. rubiginosa and F. rubiginosa f. glabrescens (F.M.Bailey) D.J.Dixon. Each taxon is redescribed. The epithet glabrescens of F. rubiginosa f. glabrescens is resurrected with a change in status. The data from the pollinator wasps strongly supports the taxonomy, with F. obliqua pollinated by Pleistodontes greenwoodi (Grandi) and F. rubiginosa sens lat. pollinated by P. imperialis Saunders. A key to the species and infraspecific taxa of F. rubiginosa as well as notes and distribution maps are provided for both species.

The taxa of Ficus are classified on the basis of the specificity and morphology of their symbiotic wasps (Agaonidae), systems of pollination, and morphology and physiology of the figs. The new classification is a modification of Corner's system with the following changes. In subgenus Ficus, subsection Eriosycea is elevated to sectional rank. Series Rivulares and Pseudopalmae do not belong to the group of Blastophaga-pollinated figs and are transferred to the new Cerotosolen-pollinated complex of subgenus Sycomorus. Two subsections, Scabrae and Varinga, are recognized in section Sycidium, and series Phaeopilosae and subsection Paleomorphe are recognized as sections. The subgenus Sycomorus is much expanded to include eight sections: Adenosperma, Neomorphe, Prostratae, Pungentes, Pseudopalmae, Rivulares, Sycocarpus, and Sycomorus.
