Taxa of genus Callicarpa in Korea were described taxonomically and studied interspecific relationships, based on the leaf length, leaf width, peduncle length, fruit width and geograhic distribution. Among 12 taxa reported previously in Korea, 3 forms of C. japonica were unifed to original species, C. japonica var. glabra was reserved, Whereas C. shirasawana was not distributed in Korea. As a result, 7 taxa belonging to 3 species, 4 varieties of genus Callicarpa remained. C. japonica complex is considered to be more advanced among the species compared with the bract shapes.

Here, we have described and illustrated a new endemic species of Scutellaria orthocalyx. This species, from Jeju-do, Korea, is clearly distinguished from other species of Scutellaria orthocalyx, especially its close relative, Scutellaria orthocalyx has relatively many leaves further down the stem. The shape of leaves begins linear and becomes lanceolate. Scutellaria orthocalyx can also have long shaped leaves on the upper part. Scutellaria baicalensis by linear, terete, fistulous and long leaves. A index to these species is provided.

In order to elucidate the intergeneric relationshiops within Korean Oleaceae including the endemic Abeliophyllum distichum, 19 species and 9 varieties of 9 genera were investigated. A cladistic analysis based on 18 characters revealed close relationships among (1) Osmanthus, Chiononthus, Fraxinus, (2) Abeliophyllum, fontanesia, Forsythia, and (3) Ligustrum, Syringa, and well accorded with the pollen morphological result. Jasminum was connected to the branch of Ligustrum possibly owing to a sampling error. A hypothesis on the origin of Abeliophyllum was drawn that it originated from Fontanesi or less probably from the common ancestor of Fontanesia and Forsythia.

To clarity the species of genus Melandrium (Caryophyllaceae) in Korea, the taxonomic characters were described and interspecific relationships were discussed to the extemal morphology with light and scanning electron microscopy. The position and size of appendages on petal, the shape and venation pattern of leaf, and the external morphology of seed and pollen were approved as the good characters to classify genus Melandrium in Korea. As the result, genus Melandrium in Korea could be arranged as 6 species, 1 variety, 1 forma. M. umbellatum was exclusively distributed in north Korea, and its taxonomic treatment was reserved.

The unrecorded plant, Aster hispidus var. leptocladus (Compositae), was reported from Mt. Palgong-san, Daegu-si, Korea and was named as 'Gin-ssuk-bu-jaeng-i' after its slender leaves. It is distinguished from var. hispidus by having glabrous linear cauline leaves with acute apex, small heads and involucre, short pappus in disc florets. It had been considered as Japanese endemic plant especially adapted to serpentine area.

Thalictrum rochebrunianum var. grandisepalum (TRG) is a Korean endemic plant, and it is widely used for edible, medicinal, landscape materials. In this study, we examined the protein and mRNA expression levels of MITF, tyrosinase, TRP-1 and TRP-2 by TRG extract (TRGE) in IBMX-treated melanocytes to evaluate the possibility of using TRG as a whitening material. IBMX were reported as melanin synthesis enhancers. It could increase intracellular melanin synthesis by activation of the microphthalmia-associated transcription factor (MITF) signaling pathway. TRGE did not show cytotoxicity at concentrations below $100{\mu}g/ml$ in B16F10 cells. TREG dose-dependently inhibited protein and mRNA levels of MITF, tyrosinase, TRP-1 and TRP-2. Therefore, we suggest that TRGE is an important natural resource for cosmetic raw materials for whitening function.

The current status of geographical distribution range of Deutzia paniculata, one of the korean endemic plants, was investigated based on the species distribution information. The information of the geographical range used for analysis includes all the published references to the distribution of D. paniculata, herbarium specimens in Korea National Arboretum (KH) including its online database: http://www.nature.go.kr, and field research. Although, D. paniculata was firstly recorded in Wonsan, Hamgyeongnam-do, North Korea, this research revelaved that D. paniculata is mainly distributed in Gyeongsangbuk-do and Gyeongsangnam-do, southern regions of the Korean Peninsula. According to the distribution map, this species was estimated on distribution edge of in Anyang region of Gyeonggi-do, Mt. Naejang of Jeollabuk-do and Mt. Taebaek of Gwangwon-do on the distribution edge. However, it was made use of intensive field survey to identify the natural population of the species in these regions. D. paniculata habitat was mainly distributed between 290 meters and 491 meters in altitude, but it was also found ranged from 936 to 959 meters in Gun-wi, Gyeongsangbuk-do, South Korea. The distribution slope was 5° to 35° and the north, N, NE and NW in the aspect. The flora of vascular plants in D. paniculata habitats was listed in 137 taxa: 54 families, 103 genera, 120 species, 2 subspecies, 12 varieties and 3 forms while Korean endemic plants were found in three taxa, Stewartia koreana, Weigela subsessilis and D. Paniculata. Based on a collection of non-biological environment and biological environment data, D. paniculata population were discussed to make strategy and basic research methods for sustainable preservation.

The vascular plants species were summarized as 479 taxa: 89 families, 260 gents, 404 species, 66 varieties, 8 forms and 1 hybrid in the whole 6 surveyed areas of eastern parts of Jirisan (Georim Valley, Baengmudong Valley, Hanshin Valley, Jungsanri Valley, Sesokpyongjeon, and Chonwangbong). Based on the list of Korean endemic plants, 26 species were recorded: Athyrium excelsius (Aspidiaceae), Abies koreana (Pinaceae), Betula ermani var. saitoana (Betulaceae) etc. The special plants from the list of Ministry of Forest, the Forest Research Institute (1997) and the Ministry of Environment (2001), 15 species were recorded: Smilacina bicolor (Liliaceae), Disporum ovale (Liliaceae), Clematis chiisanensis (Ranunculaceae) etc. And 15 species of naturalized plants were recorded: Oenothera biennis (Onagraceae), Ambrosia artemisiaefolia (Asteraceae), Carduus crispus (Asteraceae), etc. Especially, the Korean endemic plants repeatedly appeared around mountain-trails and Ambrosia artemisiaefolia (Asteraceae), also, popular were distributed in the entire studied areas.

Sonjook island is located Samsan-myeon, Yeosu-si, Jeollanam-do. All of field information was collected from January 2001 to November 2002. The vascular plants recorded as total 584 taxa, 5 forms, 60 varieties, 519 species, 365 geneta, 113 families. Sonjook islands shows the typical vegetations including the lower area of temperate region of Korean peninsula and evergreen broad-leaved forests, Pinus thunbergii forest. The Korean endemic plants were recorded as 13 taxa (5 variety, 8 species, 10 genera, 10 families), 4 taxa as rare and endangered plants (Psilotum nudum (L.) Griseb., Milletia japoniea A. Gray, Arisaema negishii Makino, Sarcanthus scolopendrifolius Makino). The naturalized plants were 23 taxa (20 genera, 9 families, 8.2％ among the total naturalized plants in Korea. This area is ecologically important place that Korea endemic plant, rare and endangered plants ranges much than area. On the one hand, threat from degraded by environmental pollution that share of naturalized plant rises gradually augment. Strong conservation policy and development control should be considered.
