Investigation of Vegetation in Soheuksan-do and Hong-do

소흑산도(小黑山島)와 홍도(紅島)의 식물자원(植物資源) 조사(調査)

For the development of natural ornamental plants, an investigation was carried out about the vegetation of Soheuksan-do and Hong-do, islands located far in the southwestesn part of the Korean peninsular. The vegetation of Soheuksan-do was abundant. The dominant species were Machilus thunbergii, Buxus microphylla var. koreana, and Camellia japonica. Regarding the development of natural ornamental plants, 27 families and 54 species were reported in this investigation. Among these species there were 8 species including Calanthe discolor, Epipachs falcata, Dendrobium monniforme, Goodyera maximowiczii, and Lipari's krameri in Orchidaceae. The vegetation of Hong-do was similar to that of Soheuksan-do, but less abundant. Supplementary 10 species were reported in this investigation. Epipactis falcata and Dendrobium moniliforme were almost exterminated in these islands because of indiscriminating gathering. Therefore these species must be protected immediately.

우리나라의 최남서단(最南西端)에 위치(位置)하는 전라남도(全羅南道) 신안군(新案郡) 흑산면(黑山面)에 속(屬)하는 소흑산도(小黑山島)와 홍도(紅島)의 식물자원(植物資源)을 조사(調査)하였다. 소흑산도(小黑山島)의 식물상(植物相)은 매우 다양(多樣)하였으며, 이중 출현빈도(出現頻度)가 많고 관상식물(觀賞植物)로도 개발(開發) 가능(可能)한 27과(科) 54종(種)을 보고(報告)하였다. 그중 난과식물(蘭科植物)은 새우난(Calanthe discolor)등(等) 8종(種)이었다. 홍도(紅島)의 식물상(植物相)은 소흑산도(小黑山島)와 매우 유사(類似)하였으나 덜 풍부(豊富)해 보였으며, 아직 미기록(未記錄)된 1종(種)을 추가보고(追加報告)하였다. 풍란(風蘭), 석곡 등(等) 기호도(嗜好度)가 높은 관상식물(觀賞植物)은 이미 절종상태(絶種狀態)에 이르고 있어 이의 보호(保護)가 절실(切實)히 요청(要請)되었다.
