This study investigated the species composition and distribution of woody plants, and flora of vascular plants of Cheonjiyeon where is located in the most southern region of Korea. Twenty-nine taxa of trees were distributed in the valley, and of these, deciduous broad-leaved trees were 13. Of the total number of 2,547 trees, 1,429 were deciduous broad-leaved trees and remainder was broad-leaved evergreen. Deciduous broad-leaved trees covered 48.7% of the tree canopy while evergreen broad-leaved trees covered only 42.3%. The total number of shrub taxa was 37 with more evergreen shrub taxa than deciduous. Evergreen shrubs occupied 64.4％ of shrub canopy while deciduous shrubs covered only 35.4％. The result of the investigation of flora showed that there are 446 taxa of flora including 114 families, 320 genera, 397 species, 1 subspecies, 39 varieties, and 9 forma. Of these, two species, Rubus hongnoensis Nakai and Lycoris chejuensis K. Tae et S. Ko, are endemic plants of Jeju Island.

Mt. Bonghwa reaches a height of 800 m (2,870 ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304 m (4,278 ft). It is important to survey the flora of Bonghwa-san in that it is a way to make out what kind of plant species exist in DMZ due to the geographical characteristics of Bonghwa-san adjacent to Korean DMZ. Therefore this study was conducted to elucidate the distribution of vascular plants and their value of Bonghwa-san.

Gwangchiryeong, located adjacent to the Korean DMZ, is a mountain pass connecting Yang-Gu, Gangwon-do with In-je. It reaches a height of 800m (2,624ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304m (4,278ft). It is important to survey the flora of Gwangchiryeong in that not only the area encompassing the waterfall and the valley along with dense old-growth forest has various plant species but also it is a way to make out what kind of plant species exist in the DMZ due to the geographical characteristics of Gwangchiryeong adjacent to the Korean DMZ. Therefore, this study was conducted to elucidate the distribution of vascular plants and their value in Gwangchiryeong.

The analysis in external morphology of Astilbe including three endemic species in Korea was undertaken. From this study, five species and three varieties of Astilbe in Korea were redescribed. Their scientific names and Korean names were also consulted. Korean Astilbe could be grouped in two Series-Series 1. Simplicifoliae; Astilbe simplicifoliae and Series 2. compositae; A. taquetii, A. microphylla, A. chiensis var. chinensis, A. chinensis var. paniculata, A. chinensis var. davidii, A. divaricata, A. koreana. Interspecific relationships of eight taxa were represented as a toxonomic model by the considering their external morphology-pubescence on floral axis and surface of leafblade, inflorescence type, ratio of petal and stamen length-and distributional range in Korea and neighboring countries.
