This paper contains the results obtained by ecological investigation of flora in Muie Island of Incheon Harbor in the western coast in Korea. 14 varieties, 147 species, 57 families and 142 genera of Tracheophyta were recorded by field investigations conducted over three times in May and July, 1976 and August, 1980. The flora of this island showed a plant community predominated by Pinus densiflora grown in miggle with Carpinus laxiflora, Quercus serrata and Rhododendron mucronulatum.
Generally, the number of plant species was scarce, but it was an unexpected result that such remote mountainous plants as Lysimachia clethroides, Syneilesis palmata and Lilium disticum etc. were encountered in a wood surrounding Seohwang-dang, the shrine of a tutelary deity, on 126-Meter Hill at the northern end of the island. There also countered in Hoyong mountain valley were deciduous broad-leved forests without pine tree which mainly consisted of Prunus leveilleana, Fraxinus rhynchophylla, Platycarya strofilada, Quercus serrata, Quercus acutissima and Acer mono. In addition, herbaceous plants, such as Syneilesis palmata, Codonopsis lanceolata and Lysima barystachy were grown as the undergrowth of these forests. Drosera rotundifolia, an unlooked-for plant, appeared in the middle of the eastern coast of the island.
Camellia japonica was grown spontaneously in Deogjeog Island 26㎞ southwest from the island, while no evergreen broa-leaved tree could be located except 2 species of Vitex rotundifolia and Euonymus japonica.
It may be considered that such simple flora of this island compared with that of land is attributed to the fact that the formation of the former took place in the period far latter than that of the latter.
