This study was performed to get more knowledge on the flora and their life form spectrum in the Hallasan Natural Reserve. The vascular plants include 83 species 35 genera 12 families of pteridophytes, 5 varieties 5 species 3 families of gymnosperm, 100 taxa in 2 varieties 98 species 58 genera 8 families of monocotyledon and 362 taxa in 3 forma 10 varieties 349 species 186 genera 65 families of dicotyledon in Hallasan Natural Reserve. The total of vascular plants is 550 taxa in 3 forma 11 varieties 536 species 284 genera 88 families. Among these, 204 species in total including 19 species of pteridophytes, 2 species of conifers, 45 species of monocotyledon and 138 species of dicotyledon are found only in the Hallasan Natural Reserve. The pteridophyte-quotient is 4.52 and floristic richness is 1.94. In the analysis of life form spectrum, there are 190 species (34.5%) of hemicryptophytes and 122 species (22.2%) of geophytes so that two life forms take large portions, 312 species (56.7%) of the vegetation in Hallasan Natural Reserve. Megaphanerophytes and microphanerophytes take 14.5% including 80 species followed by 83 species (15.1%) of nanophanerophytes, 42 species (7.6%) of chamaephytes, 29 species (5.3%) of therophytes, 24 species (4.4%) of hydrophytes and 18 species (3.3%) of epiphytes. According to the life form spectrum hemicryptophytes dominated high portions, which suggests Hallasan Natural Reserve has hemicryptophytic climate and similar to middle parts in the Korean Peninsular. The differences, however, were noticed by that it has more chamaephytes and less therophytes than that of the Peninsular and partially shows the characteristics of artic or subalpine climate.
