The genus Ficus L., containing approximately 850 species, is by far the largest genus in the Moraceae. They are mainly distributed worldwide, mainly in tropical countries. In South Korea, there are three native Ficus (including F. erecta Thunb, F. sarmentosa var. nipponica (Franch. & Sav.) Corner, and F. thunbergii Maxim.). Among them, F. erecta is effectively natural resources for the improvement of senile cognitive impairment. However, the chloroplast (cp) genome sequences and information of F. erecta have not been addressed. Therefore, in this study, we provide the complete cp genome of F. erecta and its allied species using next-generation sequencing technology. The chloroplast of Ficus species has typical structure which includes large and small single copy regions and a pair of inverted repeats (IRs). The sizes of cp genomes range from 160,276 bp to 160,603 bp. To determine the phylogenetic positions of these species, we conducted a maximum likelihood analysis using common protein-coding genes in chloroplast sequences. Also, we describe a newly developed single nucleotide polymorphism (SNP) markers using multiplex PCR to identify F. erecta based on amplification-refractory mutation system (ARMS) technique. We analyzed matK, atpB of the chloroplast genes and ITS from F. erecta and three related taxa, F. carica, F. sarmentosa var. nipponica and F. thunbergii. It provides useful information for molecular identification between F. erecta and related Korean native species.

The vegetation of Odongdo island was surveyed over twenty-nine times from April, 1982 to August, 1983. This island is located at 127。46'05'∼127。39'37'E. longitude and 34。40'20'∼34。48'14'N. latitude. The vegetation of this island consisted of 94 families, 261 genera, 314 species, 53 varieties and 6 formae. And among them were 170 species of woody plants and 203 species of herbs. The community of evergreen broad-leaved trees comprised a total of 44 species including Sasa coreana Nakai and camellia japonica L. and the distribution of evergreen broad-leaved trees was good in this island as a whole. Sasa coreana Nakai, Castanopsis cuspidata var. sieboldii Nakai, Ficus erecta Thunb., Ficus nipponica Fr. et Sav, Stauntonia hexaphylla (Thunb.) Decne, Cinnamomum japonicum Sieb., Machilus thunbergii S. et Z., Lozoste lancifolia (S. et Z.) Bl., Ilex intergra Thunb., Camellia japonica Thunb., Hedera rhombea Bean and Ardisia japonica Bl. etc. in this island were autochthonous flora and their preservation is required.

The flora of vascular plants in Jangsanbong located at Busan Metropolitan City was investigated from April 2003 to April 2004. Vascular plants in the surveyed area were 254 taxa that belonged to 78 families, 175 genera, 218 species, 34 varieties, and 2 forma. Among them, 20 taxa of evergreen broad trees, 31 taxa of naturalized plants were identified, and especially Rubus trifidus was first recorded in Busan. In the upper part of a circular road dominant species was Pinus thunbergii. In the lower part of a circular road and the coastal area, dominant species were Platycarya strobilacea, Clerodendron trichotomum, Euscaphis japonica, Quercus aliena, Quercus dentata, Mallotus japonicus, which distribute mainly in the subtropical and temperate zone. In the surveyed area, the canopy consistsed of tall trees, Pinus thunbergii, and the understratum were trees such as Eurya japonica, Ficus erecta, Ligustrum japonicum, Prunus sargentii, and Celtis sinensis var. japonica.

To investigate the coastal forest structure and its ecological characteristics in Busan, four typical sites, Taejongdae, Molundae, Amnam Park, and Igidae, were selected and surveyed. These sites are famous coastal areas in Busan. According to the analysis of vegetation structure, Pinus thunbergii was a dominant species at the canopy layer in all sites. But at the understory layer, Eurya japonica in Taejongdae and Molundae, Ficus erecta in Igidae and Eurya japonica and Prunus sargentii in Amnam Park were dominant species.

This paper contains the results obtained by ecological investigation of flora in Sogumoon Island of the southern coast in Korea. Fifty varieties, 455 species, 322 genera and 104 family of Tracheophyta were recorded island showed a plant community predcominated by Pinus thunbergii grwon in miggle with Castanopsis cuspidata var. sieboldii, Machilus thunbergii, Litsea japonica, Albizzia julibrissin, Carpinus coreana, Carpinus laxiflora, Mallotus japonica and Clerodendron trichotomum. Sixtythree species in Sogumoon Island and 64 species in Pogil Island of evergreen broad-leaved trees were recorded by this investitgations. The plant resources of this island were 203 species. The evergreen broad-leaved trees of this island wre valuable for landscaping material plants and the evergreenherbs were valuable for foliage-plants resources. The flora breaking in this island was due to cuttinf for fuel and grazing cattle and goats. Therefore Machilus thunbergii, Ardisia japonica, Ficus miponica, Kadsura japonica, Daphniphyllum macropodum, etc. should be preserved. Autochonous flora of Buxus microphyllac, Fius erecta, Machilus thunbergii, Kadsura japonica, Ardisia japonica, Mitchella undulata, etc. should be preserved.

This study was carried out to analyze vegetation and soil characteristic of Osmanthus insularis community, Geomundo. The Osmanthus insularis community was classified into three subcommunities: Mallotus japonicus subcommunity, Ficus erecta subcommunity, Raphiolepis umbellata subcommunity. The importance value of Camellia japonica, Osmanthus insularis, Ligustrum japonicum, Litsea japonica Mallotus japonicus, Pinus thunbergii and Ficus erecta in Osmanthus insularis community were 76.11%, 75.91%, 37.24%, 21.99%, 18.35%, 17.64% and 11.91%, respectively. According to the DBH analysis. Osmanthus insularis showed formality distribution style among the entire community. Their dominance is expected to continue. But the young plant individual were low density, importance value reduced. In the study sites, soil organic matter, nitrogen, available phosphorous and soil pH were ranged from 19.11~24.62%, 0.73~1.18%, 11.61~27.98mg/kg and 6.11~6.37, respectively. According to the result of survey Osmanthus insularis individual, the female plants individual were 57.90%, the male plants individual were 42.10%.

This study was first performed since 1933 to investigate the flora of $\check{O}$ch$\check{o}$ng Island located in the middle part of Yellow Sea. A number of vascular plants recognized through in this survey were 319 taxa belonging to 78 families, 213 genera, 279 species, 38 varieties and 2 forma in which 38 species were newly recorded and 26 species of evergreen plant were identified. The Pteridophyta distributed in this island were 10 species and the naturalized plants were 4 species. And the coefficient of cryptogram(Pte-Q) and Urbanization Index(UI) as to the destruction degree of natural vegetation showed a value of 0.81, 3.64 respectively.
