INTRODUCTION
The mountain forests, one of them in Java Island area,
are the last zone of in situ conservation of plant species
from deforestation and exchanging of land which has been
carried out in the last nearest time. The requirement of food
and settlement has pressed to open much larger land
(Setiawan and Sulistyawati 2008; van Welzen and Raes
2011; Tsujino et al. 2016). On the other hand, diversity loss
and dynamic vegetation succession that were often found in
the mountain forest of Java (Zuhri and Mutaqien 2011;
Purwaningsih et al. 2017; Zuhri et al. 2018), will encourage
innovation to the conservation of the flora on every
mountain, such as in Burangrang Nature Reserve.
Mount Burangrang NR is part of the tropics mountain
in West Java; this area is up to 2.700 ha and covers two
regencies namely Purwakarta and Subang (BBKSDA
2016). Ecologically, Burangrang Nature Reserve area has
an important part as a territory for water catching and water
reservoirs for its surrounding area. Besides that, Mt.
Burangrang becomes a natural habitat of Java primate, such
as owa java, lutung and surili, so that flora conservation to
support the animals woof must be regarded (BBKSDA
2016). On the other hand, some areas of Burangrang
Nature Reserve are adjacent immediately with agriculture
and plantation so the plants are susceptive to be coming
into natural forest, as reported by Zuhri et al. (2018) in
Mount Gede.
The book Flora of Java composed by Backer and
Bakhuizen v.d. Brink (1963; 1965; 1968) in comprehensive
way consists of the description of flora in Java and The
Mountain Flora of Java (van Steenis 1972; 2006).
Specifically, this book describeshighlands flora and it
becomes the most references inventory of the flora in
Mount Burangrang Nature Reserve. More than 400 species
of highlands flora, including Nephenthes gymnamphora,
Morinda sarmentosa, and Vernonea cymosa are found in
Mt. Burangrang Nature Reserve area (Van Steenis 2006).
However, the list of flora must be made clear. So, this
reseach is purposeful to get the data about the kinds of flora
in the hills forest of Mount Burangrang Nature Reserve,
Purwakarta, West Java, Indonesia.
MATERIALS AND METHODS
Study area
The study was conducted in the submontane forest on
Mt. Burangrang Nature Reserve, Purwakarta District, West
Java Province, Indonesia at 946 to 1104 m asl., in
B I O D I V E R S I T A S
20 (8): 2197-2205, August 2019
2198
coordinates: 06°43’37.8” S to 6°43’441” S and
107°33’21.5” E to 107°33’07.8 E. The topography
condition of the study site was rather flat and uphill with
slopes of 10-45°. Microclimate measurements were carried
out during study, i.e. temperature (23.2-27.9°C, in the
afternoon), air humidity (up to 92%), pH (6.2-7.2), soil
humidity (50 to 90%), and light intencity (137 to 2240 lux).
Procedures
There are two types of data taken from the site, i.e. (i)
list of vascular plants, both in the plot and around
observation plots, and (ii) data of floristic composition and
vegetation structure.
Inventory of vascular plants
Sampel were recorded using exploration methods
(Rugayah et al. 2004), in the hiking traill of Mt.
Burangrang Purwakarta (±3.2 km length) (Figure 1). The
Species were recorded based on their scientific names and
families, while the unidentified species were made
herbarium voucher referring to de Vogel (1987), to be
identified later using an identification book such as Flora
of Java (Backer and Bakhuizen v.d. Brink 1963; 1965;
1968), Varenflora voor Java (Backer and Posthumus
1939), The Mountain Flora of Java (van Steenis 2006), A
Revised Flora of Malaya (Holttum 1966), Flora Malesiana
Vol. 4 (2012) and other papers (Zhu et al. 2012;
Girmansyah 2008; Hadiah 2007). The naming of species,
genera, families and taxon level refers to the Angiosperm
Phylogeny Group classification (1998; 2003; 2009; 2016)
for flowering plants, while for lycophytes and fern, it refers
to Christenhusz et al. (2011) and Rothfels et al. (2012).
Vegetation sampling
Collecting data procedure was done by the vegetation
analysis technique using purposive sampling (plot) in
depended path. Sampling was done using four plots in
altitude of 946-1110 m asl.. Every plot has magnitude of
10x50 m2, which is then divided into 5 subplots (Figure 2).
For vertical category (dbh>10 cm), a subplot with
measurement of 10x10 m2 is used, but on the boundary
(dbh<10) and low flora, a subplot with measurement of 5x5
m2 is used. The species and the quantity of plants in every
sub plot are recorded. The diameter of high pectoral
timbers is measured (dbh) and recorded. Measurement at
the area covers the species, the quantity of individual on
every species, the diameter of tree, and height of tree.
The measurement analysis of diversity of plants and
low plants uses index as follow (Ismaini 2015), namely, the
index of diversity of Shannon-Wiener (Magurran 1988):
Where, H’: the result of diversity index of Shannon-
Wiener and pi: proportion of every species i. so H’ is sum
of whole pi ln pi for all species in community.
The Index of Species Evenness: (E)=H’/ln S, where E:
index of species evenness, H’: the result of diversity index
of Shannon-Wiener, and S: sum of species which have
been observed.

Data analysis
Analysis of structure and vegetation was done by
counting Importance Value Index (IVI) by formula:
IV = RD+RF+RDo,
Where, RD: Relative Density, RF: Relative Frequency,
RDo: Relative Dominance (%). The Calculation of INP,
according to Soerianegara and Indrawan (1982), is as
follow:
RD = number of individuals of a spesies
total number of individual x 100%
RF = frequency of a species
sum frequency of all species 𝑥 100%
RDo = dominance of a species
dominance of all species 𝑥 100%
RESULTS AND DISCUSSION
List of vascular plants in Mt. Burangrang Nature
Reserve
A total of 208 species of vascular plant (more or less
35% species of the western mountain flora of Java)
belonging to 85 families have been recorded along transect
on Block Cipulus Mt. Burangrang, both in the plots or
outside the plots (Table 1). Based on the Angiosperm
Phylogeny Group classification (1998; 2003; 2009; 2016),
these species can be classified into: basal family of
angiosperm (1 species), magnoliids (21 species), monocots
(33 species), eudicots (1 species), superrosids (1 species),
rosids (74 species), superasterids (5 species), and Asterids
(47 species), plus 23 species of fern and 2 species of
lycophytes. The gymnosperms group was not found in this
observation.
Based on their habits, the tree type with 72 species has
more member group than other types, such as: herbs,
shrubs, climbing, epiphytes, creeping and palms type, with
56 species, 30 species, 27 species, 16 species, 5 species,
and 2 species respectively. Lauraceae (10 species) and
Fagaceae (2 species), the typical families in the
submontane to montane forest, can also be found in this
area. Other families with the high number of species
members in study are Urticaceae (9 species), Rubiaceae (8
species), Moraceae (7 species), Orchidaceae (6 species),
Phyllanthaceae (6 species), Arecaceae (6 species) and
Araceae (6 species).
A total of 14 species belongs to IUCN redlist, with
categories of least concern (12 species), vulnerable (1
species), and endangered (1 species). Furthermore,
Castanopsis argentea, Pinanga javana and
Amorphophallus decus-silvae are included in protected
plants (Permen LHK No 20 tahun 2018). Furthermore, A.
decus-silvae , wellknown as endemic flora of Java
(Yuzzami et al. 2017), were found at flowering phase (up
to 2.15 m high). Other species, i.e. Kadsura scanden and
Calamus ciliaris belonging to 200 of rare species in
Indonesia, were also found here (Mogea et al. 2011). Some
of pterydophytes belong to IUCN red list based on an
assesment by Fernando et al. (2008) in Philiphines, i.e.
Asplenium nidus L. (VU), Cyathea contaminans (Wall. Ex
Hook) Copel. (VU), Huperzia squarrosa (G. Forst.) Trevis.
(EN), Aglaomorpha heraclea (Kuntze) Kopel. (VU), and
Microsorum membranifolium (R.Br.) Ching (LC).
In addition to native species of Java, exotic species
were also found in Mt. Burangrang Nature Reserve, such as
Coffea arabica, C. canephora, Melastoma affine, Clidema
hirta, Chromolaena odorata, Austroeupatorium
inulifolium, Ageratina riparia, Lantana camara and
Brugmansia suaveolens. Brugmansia suaveolens, M.
acuminata, A. riparia, L. camara and C. odorata have been
naturalized in Java for long years ago (Backer and
Bakhuizen v.d. Brink 1963; 1965; 1968; Tjitrosoedirdjo et
al. 2016). Firstly, these species are imported for medicinal,
food or ornamental plants in the Dutch colonial through
botanic gardens. Brugmansia suaveolens, for example, was
imported from the Americas for ornamental plant
(Bruggeman 1927; Dakkus 1930), but today, it grows wild
on the banks of rivers, on moist areas or on little shade and
it can also be found in various regions in Indonesia
(Wahyuni and Tjitrosoedirdjo 2013; Zuhri and Mutaqien
2013; Junaedi 2014; Sutomo et al. 2018). Exotic species
can threaten as invasive as reported in various regions in
Indonesia (Setiawan and Sulistyawati 2008; Wahyuni and
Tjitrosoedirdjo 2013; Zuhri and Mutaqien 2013;
Tjitrosoedirdjo et al. 2016; Sutomo et al. 2018), so we need
to be aware about this.
Floristic composition and structure vegetation
Diversity of tree in the observation plot in Mt. Burangrang
Nature Reserve
A total of 48 individuals of tree (belong to 14 species
from 10 family) were found in observation plot which were
dominated by pioneer species i.e. Villebrunea integrifolia,
Antidesma tetrandum, Acronychia trifoliolata and
Dendrocnide stimulans (Table 2). It indicated that forest of
lower submontane of Blok Cipulus Mt. Burangrang is
disturbed or experienced secondary succession. Data of
diameter distribution of tree (Figure 3) supported this
statement too. Small trees (dbh<50 cm) dominate more
than large trees (dbh>50 cm). The Shannon-Wienner’s
diversity index (H’ value=1.85) on tree level shows the
result of medium category. While, the equality value only
0.35 (J<0.5) indicates the spread of species that are not
evenly distributed at the tree level.
Villebrunea integrifolia (Gaudich.) Miq. shows
increasing trends on the number of individual in observed
plot. Increases of individual can be seen from each plot and
Villebrunea integrifolia (Gaudich.) Miq. has the highest
number of individual which was found throughout the area.
Furthermore, Plot 2 is the most distributed area containing
Villebrunea integrifolia (Gaudich.) Miq., Antidesma
tetrandum Bl., Acronychia trifoliolata Zoll & Moritzi,
Dendrocnide stimulans (L.f) Chew, and Litsea angulata Bl.
Some species of lower submontane, such as, Litsea

diversifolia Bl., L. mappacea Boerl. and L. angulata Bl.
were also found here (Backer and Bakhuizen v.d. Brink
1963; Sunarto et al. 2019). For, the type of mountain flora,
only 1 individual for each type were found, while Piper
aduncum L., a well-known exotic species (Hartemink
2010), may only be found in one plot, but not in other plot.
The distribution of P. aduncum species is more commonly
found in riparian areas with a little light.

CAHYANTO et al. Floristic survey of vascular plant in Mt. Burangrang, Indonesia
2203
The density level and number of tree species in Mt.
Burangrang show lower value than other forest type in the
similar altitude in Java (Tabel 3). Likewise, the canopy
covering in the tree level shows a “gap” in almost all
observation plots. It brings to a conclusion that vegetation
in Mt. Burangrang has been disrupted and has come to a
succession period as it has happened in Mt. Wilis
(Purwaningsih et al. 2017). The smaller plot area causing
low density and species were found.
Domination of mountain flora, ex. Aglaia eximia and
Polyalthia subcordates, showed a positive regeneration
trend compared with a high trees (Table 4). Polyalthia
subcordata, Sambucus javanica, and Aglaia eximia were
commonly found on those heights, as reported by Zuhri et
al. (2018) in the remnant forest of Cibodas Botanic
Gardens. Pinanga javana (Pinang jawa), is also spread
throughout observation plots. Pinanga javana grows from
low land to high land on Mt. Slamet area, Baturaden
(Zulkarnaen et al. 2019).

Diversity of undergrowth in the observation plot in Mt.
Burangrang Nature Reserve
The existence of undergrowth species plays an
important role in maintaining the microclimate in the land.
Achyranthes bidentata Blume., Elatostema strigosum
Hassk., Homalomena pendula (Blume) Bahk.f., Etlingera
coccinea (Bl.) S. Sakai & Nagam and Boehmeria nivea (L.)
Gaudich are the 10th species that dominate the forest of
Mt. Burangrang (Table 5). The high value of importance
shows the success of a plant in controlling the area by
growing and developing with the habitat which has high
humidity and relatively acid-netral pH, although there were
some wider gaps in some areas due to fallen trees. This
shows that Achyranthes bidentata Blume is a dominant
crop, with wide adaptability and tolerance to environmental
factors (Ismaini et al. 2015). But, there was also a threat
from the plants having a high growth rate such as
Etilingera coccinea which has the potential as an invasive
species as reported in several regions in Indonesia and this
needs attention. Etlingera coccinea has a tight rhizome and
forms a population that can inhibit other types of growth
(Zuhri and Mutaqien 2013; Tjitrosoedirdjo et al. 2016).
Homalomena pendula and Boehmeria nivea were found
throughout the observation plot. The production of large
amounts of seeds can accelerate the spread of these species
even further into the forest. Coffee arabica was only be
found in plot I, which was directly adjacent to community
plantations and the plot was a former plantation land
cultivated by communities that had been planted with
coffee decades ago.
The conclusion, Mt. Burangrang Nature Reserve stores
a large variety of vascular plants including some rare plants
as listed in IUCN redlist and nationally, but the condition
of the forest in this zone shows disturbed forest which
needs recovery as soon as possible. The presence of
invasive trees could be slow down the succession toward
climax. Further, research on interaction of biodiversity and
surrounding community need to be done later to support
the continuation of forest life in this area.

Mount Leuser National Park is one of the largest conservation areas and plays important ecological and economic functions. To support forest management, it is important to gain current vegetation data. The sampling method of a 0.1 hectare plot was carried out on two sampling sites in the submontane zone of Ketambe Resort, Mount Leuser National Park, Aceh. The diversity of trees was not significantly different, while species composition was different. Site one was dominated by Syzygium spp. and Shorea platyclados, while site two was dominated by Altingia excelsa and Bridelia glauca. Lauraceae, Myrtaceae, and Dipterocarpace families dominated in both sites. Tree structures formed three strata and showed a good capacity for forest regeneration. The aboveground biomass of site one was higher than site two due to the presence of more large trees. Pioneer species, cultivated plants, a low average wood density, and low aboveground biomass indicated secondary forest characteristics in both sites. Abstrak: Taman Nasional Gunung Leuser merupakan salah satu kawasan konservasi yang terluas dan memiliki fungsi ekologi dan ekonomi yang penting. Data vegetasi terkini penting didapatkan untuk mendukung pengelolaan hutan. Metode sampling dengan plot 0.1 hektar dilakukan di dua lokasi pada zona submontana Resort Ketambe, Taman Nasional Gunung Leuser, Aceh. Keanekaragaman jenis pohon tidak berbeda secara nyata sementara komposisi jenis berbeda. Lokasi satu didominasi oleh Syzygium spp. dan Shorea platyclados, sementara lokasi dua didominasi oleh Altingia excelsa dan Bridelia glauca. Suku Lauraceae, Myrtaceae dan Dipterocarpace mendominasi pada kedua lokasi. Struktur pohon membentuk tiga strata dan menunjukkan kemampuan regenerasi hutan yang baik. Biomassa pohon di atas permukaan pada lokasi satu lebih tinggi dibandingkan lokasi dua karena lebih banyaknya pohon berukuran besar.

... The abundance of exotic understory species is an indicator for vegetation succession, as reported by Grant & Loneragan (2001). At the sapling level, the understory woody-form can be used to predict the stand regeneration (Afrianto et al., 2016;Cahyanto et al., 2019;de Carvalho et al., 2017;Irfani, 2016;Rasnovi, 2006;Susanti, 2014). ...

The understory is an important component in the tropical forests, particularly to contribute to ecosystem services function and playing on succession. However, the study on their existence related to the zonation effect in an ex-situ conservation is still lacking. This study aimed to compare the structure and composition of the understory in the two blocks of Ir. Djuanda Forest Park, Bandung. Data collection was carried out through vegetation analysis using plot methods (sampling plots). A total of 40 sampling plots of 5m x 5m were made in two observation blocks. The Importance Value Index (IVI) for each species was calculated based on their relative density and relative frequency. Seventy-three species of understory from 38 families were found in the observation plots, dominated by Araceae and Moraceae families. The composition of the protected block has higher species richness than the utilization block due to the differences in microclimates conditions. Calliandra calothyrsus, known as an invasive species, has the highest IVI indicating high adaptability to open habitats in the utilization block, while two native species, Plectranthus sp. and Chlorathus elatior, dominate in the protection block. Based on these findings, we showed that forest zonation drives exotic and native species abundance in the ex situ conservation area. Abstrak: Tumbuhan bawah merupakan salah satu komponen penting dalam vegetasi hutan tropis, terutama dalam pelayanan ekosistem dan berperan dalam proses suksesi. Namun, penelitian mengenai keberadaannya dikaitkan dengan pengaruh zonasi di kawasan konservasi secara ex situ masih jarang. Tujuan penelitian ini untuk membandingkan struktur dan komposisi tumbuhan bawah pada dua blok yang berbeda di kawasan Taman Hutan Raya Ir. Djuanda, Bandung. Pengambilan sampel menggunakan analisis vegetasi dengan metode plot (petak contoh). Sebanyak 40 plot kecil berukuran 5mx5m di kedua blok pengamatan. Indeks nilai penting (INP) setiap jenis dihitung berdasarkan kerapatan relatif dan frekuensi relatifnya. Sebanyak 73 jenis dalam 38 suku tumbuhan didata di dalam pengamatan, yang didominasi dari suku Araceae dan Moraceae. Berdasarkan jumlah jenis tumbuhan penyusunnya, blok perlindungan memiliki jenis yang lebih banyak dibandingkan dengan blok pemanfaatan berkaitan dengan berkaitan dengan perbedaan kondisi iklim mikro di kedua blok tersebut. Jenis Calliandra calothyrsus, dikenal sebagai tumbuhan invasif, memiliki nilai INP tertinggi menunjukkan kemampuan adaptasi yang tinggi pada habitat terbuka di blok pemanfaatan, sedangkan tumbuhan asli pegunungan jawa, Plectranthus sp. dan Chloranthus elatior mendominasi pada blok perlindungan. Berdasarkan hasil temuan ini, kita menyarankan bahwa zonasi mempengaruhi kelimpahan tumbuhan eksotik dan asli di kawasan konservasi tumbuhan secara eksitu.

An understanding of the structure and composition of stands in a conservation area is needed to support sustainable management strategy. However, this information in the Mount Tilu Nature Reserve, Bandung District, West Java area is still lacking. This research was aimed to analyze the structure and composition of tree species in the block of Malagembol forest, Mt. Tilu NR. Data collection was carried out through vegetation analysis using sampling plot method with size of 10x100 m 2 at three-level altitudes of 1530 m, 1745 m, and 1950 m asl. Observation parameters included species names, number of individuals, and diameter at breast height (dbh). Data were analyzed to determine the floristic composition, species structure based on their diameter class, relative basal area, diversity indices, and analysis of the importance of the main components of trees species through Principal Component Analysis (PCA). A total of 32 tree species from 23 families was found in the observation plots which was dominated by Fagaceae, Lauraceae, and Myrtaceae families. Some pioneer plants covered the gap in vegetation due to minor disturbance and residual damage in the past. Nonetheless, the dominance of stands with small diameters indicated good regeneration status following such disturbance. Based on these findings, we recommend protecting the vegetation in Mt. Tilu NR by limiting community activities that can disturb the forest.

Biodiversitas 23: 5491-5501. Begonia (Begoniaceae) belongs to Section Platycentrum-Sphenanthera Group which has a wide distribution from Sumatra to the Lesser Sunda Islands and Sulawesi. Information on B. multangula genetic variability and intraspecies relationships based on molecular characters is critical for developing appropriate strategies in conservation biology, breeding activities, and many other applied fields. The genetic variability and interspecific relationships of B. multangula in Indonesia were investigated using sequence data from the atpB-rbcL intergenic spacer (IGS) cpDNA regions. The atpB-rbcL IGS fragment was amplified using atpB-1 as the forward primer and rbcL-1 as the reversed primer. Genetic variations were found in the length of the sequence and nucleotide divergences in the atpB-rbcL IGS region. The genetic distance between 822 fixed sites ranged from 0 to 0.61%. Eighteen of the 822 sites (99.27%) analyzed were invariable, six sites (0,73%) were variable consisting of 4 singleton variable sites and two parsimony informative sites, and twelve sites were gaps. The phylogenetic relationships generated by B. multangula based on the atpB-rbcL IGS sequence analysis indicated the genetic variation and divided it into two clades. However, the clustering pattern of B. multangula specimens resulting from molecular analysis based on atpB-rbcL IGS sequences did not show the geographic clustering grouping pattern.

A permanent plot is a powerful tool to study the vegetation’s dynamics and regeneration in the forest ecosystem. This study presents the first four-year tree vegetation monitoring in a one-hectare permanent plot established in a mixed forest of Mount Papandayan (MP) Nature Reserve, Indonesia. Besides studying the structure and floristic tree community composition in the plot, this study aims to study the changes and in mortality and growth of the tree community after four years of plot establishment. A one-hectare permanent plot was established in 2010 and all trees inside the plot with a diameter over 5 cm were tagged and measured in 2011 and 2015. There were 1,820 trees from 33 species and 20 families recorded during the first monitoring in 2011. Four years later, there were more trees recorded (1,845 trees) with an average growth rate of 1.17 cm. The mortality rate (2.8%) was lower than the recruitment rate (4.2%) and there were no changes in the domination of Distylium stellare. The results of this study will help to provide the preliminary data on actual in situ tree mortality and growth, which will help to develop a more complete tree species selection criteria for MP restoration.

Mount Tujuh is a part of Kerinci Seblat National Park (KSNP) conservation area which still has relatively good forest sites. Even so, forest encroachment and agricultural land clearing that is still carried out by the surrounding community can threaten the conservation area. In addition, the diversity of plants is still not widely known. Given this, research on plant diversity and conservation efforts in Mount Tujuh is important. The research was conducted through exploration and collection of plants in submontane and montane zones at 1400 to 2040 masl. Exploration of plants was done using the exploration method through a predetermined path. An exploration resulted at least 71 families (58 families of seed plants and 13 families of ferns) and 107 genera (88 genera of seed plants and 19 genera of ferns) of plants were found in Mount Tujuh forest. From that, there are threatened species according to IUCN Red List, namely Castanopsis argentea (EN), Taxus wallichiana (EN), and Styrax benzoin (VU). In addition, there are five Sumatran endemic plants, namely Impatiens tujuhensis, Impatiens rubriflora, Pinalia dura, Rhododendron pubigermen, and Rhododendron rarilepidotum. During the exploration, 614 living plant specimens were also collected for ex-situ conservation in Cibodas Botanical Garden (CBG). In addition, 30 herbarium specimens were also collected. The collected species have various potential benefits, including as food, ornamental, medicine, and building materials. The results of this study are expected to be used as a basis for consideration in the development of plant conservation program in Mount Tujuh forest, KSNP, Jambi.

Weeds inventory in Indonesia has been conducted and published since the colonial time, dealing with weed species in specific conditions and continuing up to now. Weed problems varied with different types of crops and habitats and differed from time to time. Weeds in agricultural production systems have long been recognized, recently environmental weeds or known as Invasive Alien Plant Species (IAPS) have been received increasing attention in Indonesia because their recognized impact on native biodiversity. Since the issue on IAPS rased during the "Earth Summit Conference" in Brazil in 1992, IAPS have drawn more attention in Indonesia, and Indonesia has ratified the Convention on Biological Diversity in 1994. After the year of 2000, articles and list of IAPS scattered in several publications, mostly reported from National Park and Botanical Garden. Some species recorded have drawn more attention, because of its potential invasiveness and threat to the community. Some important species are described in this paper.

Cibodas Botanic Garden area is adjacent with natural forest of Mt. Gede Pangrango National Park which consequences both vegetation in the border area are influence each other. The aims of this research were to study plant vegetation of forest area adjacent to Cibodas Botanical Garden and compare it with forest interior using transect method. The results showed that species richness in forest interior were higher than adjacent forest area. Furthermore, number of tree species, basal area and Shannon-Wienner diversity index in forest boundaries were higher rather than forest interior. Habitats along the forest edge were inhabited by trees with large dbh and low tree density. While trees inhibited forest interior areas with high density but small in size. The trees in forest interior were dominated by Schima wallichii, Lithocarpus pallidus and Turpinia sphaerocarpa. While trees in the forest boundary vegetation were dominated by Engelhardtia spicata, Litsea firma and Lithocarpus indutus. The tree age structure of forest interior and forest edge showed an inverted J-pattern and flat pattern respectively. Meanwhile, tree communities on edge forest vegetation showed similar age structure, especially in middle diameter class.

Abstrak Dilakukan inventarisasi tumbuhan eksotik di empat lokasi hutan sisa Kebun Raya Cibodas (KRC) dan analisis kluster untuk melihat peranan faktor lingkungan terhadap keberadaan spesies eksotik. Diperoleh sebanyak 26 spesies tumbuhan eksotik di dalam empat hutan sisa KRC. Spesies ini berasal dari 23 marga dan 14 suku. Analisis kluster menunjukkan bahwa pengelompokan nilai faktor lingkungan yang dianalisis bersinergi dengan kelimpahan populasi spesies eksotik tersebut di dalam hutan sisa KRC. Kesesuaian antara hasil analisis kluster dan kelimpahan populasi tumbuhan eksotik menunjukkan peranan faktor lingkungan terhadap keberadaan dan kelimpahan jenis tumbuhan eksotik di hutan sisa KRC. Hasil informasi inventarisasi tumbuhan eksotik di hutan sisa KRC merupakan informasi dasar yang dapat digunakan oleh pengelola KRC dalam rangka pengelolaan tumbuhan eksotik terutama yang bersifat invasif. Perlu dilakukan kajian lanjutan tentang tumbuhan eksotik di hutan sisa KRC untuk menentukan spesies eksotik mana yang harus diprioritaskan pengelolaannya untuk meminimalisasi dampak tumbuhan eksotik dan invasif terhadap ekosiostem alami di KRC. Kata kunci: analisis vegetasi, hutan sisa, Kebun Raya Cibodas, konservasi, tumbuhan invasif Abstract Due to potential impact of invasive alien (exotic) species to the natural ecosystems, inventory of exotic species in the Cibodas Botanic Gardens (CBG) remnant forest area is an urgent need for CBG. Inventory of exotic species can assist gardens manager to set priorities and plan better responses for possible or existed invasive plants in the CBG remnants forest. The objectives of this study are to do inventory of the exotic species in the CBG remnant forest and to determine whether several environmental variables play role to the existence of exotic species in the CBG remnant forests. There are 26 exotic plant species (23 genera, 14 families) found and recorded from all four remnant forests in CBG. Cluster analysis of four environmental variables shows that clustering of environmental factors of exotic species correlates with the abundances of those exotic species. The relation between environmental factor clusters and the abundance of those exotics signify the role of environmental variables on the existence of exotic plant species. The information of exotic plant species in the Buletin Kebun Raya Vol. 17 No. 1, Januari 2014 2 | remnants forest is the base information for gardens manager to manage exotic species in CBG remnants forest. The relation of several environmental factors with exotic species abundance could assist gardens manager to understand better the supportive and or suppressor factors of exotics in the CBG remnants forest. Further study on these species is needed to set priorities to decide which species should be treated first in order to minimize the impact of exotic plant species to native ecosystem of CBG.

Recent cladistic analyses are revealing the phylogeny of flowering plants in increasing detail, and there is support for the monophyly of many major groups above the family level. With many elements of the major branching sequence of phylogeny established, a revised suprafamilial classification of flowering plants becomes both feasible and desirable. Here we present a classification of 462 flowering plant families in 40 putatively monophyletic orders and a small number of monophyletic, informal higher groups. The latter are the monocots, commelinoids, eudicots, core eudicots, rosids including eurosids I and II, and asterids including euasterids I and II. Under these informal groups there are also listed a number of families without assignment to order. At the end of the system is an additional list of families of uncertain position for which no firm data exist regarding placement anywhere within the system.

An update of the Angiosperm Phylogeny Group (APG) classification of the orders and families of angiosperms is presented. Several new orders are recognized: Boraginales, Dilleniales, Icacinales, Metteniusiales and Vahliales. This brings the total number of orders and families recognized in the APG system to 64 and 416, respectively. We propose two additional informal major clades, superrosids and superasterids, that each comprise the additional orders that are included in the larger clades dominated by the rosids and asterids. Families that made up potentially monofamilial orders, Dasypogonaceae and Sabiaceae, are instead referred to Arecales and Proteales, respectively. Two parasitic families formerly of uncertain positions are now placed: Cynomoriaceae in Saxifragales and Apodanthaceae in Cucurbitales. Although there is evidence that some families recognized in APG III are not monophyletic, we make no changes in Dioscoreales and Santalales relative to APG III and leave some genera in Lamiales unplaced (e.g. Peltanthera). These changes in familial circumscription and recognition have all resulted from new results published since APG III, except for some changes simply due to nomenclatural issues, which include substituting Asphodelaceae for Xanthorrhoeaceae (Asparagales) and Francoaceae for Melianthaceae (Geraniales); however, in Francoaceae we also include Bersamaceae, Ledocarpaceae, Rhynchothecaceae and Vivianiaceae. Other changes to family limits are not drastic or numerous and are mostly focused on some members of the lamiids, especially the former Icacinaceae that have long been problematic with several genera moved to the formerly monogeneric Metteniusaceae, but minor changes in circumscription include Aristolochiaceae (now including Lactoridaceae and Hydnoraceae; Aristolochiales), Maundiaceae (removed from Juncaginaceae; Alismatales), Restionaceae (now re-including Anarthriaceae and Centrolepidaceae; Poales), Buxaceae (now including Haptanthaceae; Buxales), Peraceae (split from Euphorbiaceae; Malpighiales), recognition of Petenaeaceae (Huerteales), Kewaceae, Limeaceae, Macarthuriaceae and Microteaceae (all Caryophyllales), Petiveriaceae split from Phytolaccaceae (Caryophyllales), changes to the generic composition of Ixonanthaceae and Irvingiaceae (with transfer of Allantospermum from the former to the latter; Malpighiales), transfer of Pakaraimaea (formerly Dipterocarpaceae) to Cistaceae (Malvales), transfer of Borthwickia, Forchhammeria, Stixis and Tirania (formerly all Capparaceae) to Resedaceae (Brassicales), Nyssaceae split from Cornaceae (Cornales), Pteleocarpa moved to Gelsemiaceae (Gentianales), changes to the generic composition of Gesneriaceae (Sanango moved from Loganiaceae) and Orobanchaceae (now including Lindenbergiaceae and Rehmanniaceae) and recognition of Mazaceae distinct from Phrymaceae (all Lamiales).
