Abstract

Sedum tosaense Makino (Crassulaceae), an unrecorded species in Korean flora, was collected from parasitic crater, Sangumburi in Jocheon-eup Bukjeju-gun, Jeju-do. This species is most similar to S. bulbiferum and S. orizifolium, but differs in some substantial characters. S. tosaense is perennial and stoloniferous herb with bulbils on stems, while S. bulbiferum is annual or biennial herb without bulbils in leaf axil. In addition, S. tosaense has leaves emarginate at apex whereas S. bulbiferum has leaves somewhat uneven at apex. the leaves of S. tosaense are conspicuously flattened and spatulate in shape at the stem without flowers, but those of S. orizifolium, are terete or slightly flattened and linear to narrowly oblong in shape.

제주도 산굼부리 분화구내에 생육하는 돌나물과(Crassulaceae)에 속하는 주걱비름(Sedum tosaense)을 채집하여 국내 미기록 종으로 보고한다. 본 종은 말똥비름(S. bulbiferum)과 땅채송화(S. orizifolium)와 유사하지만 말똥비름은 포복경을 내지 않는 1년생 또는 2년생 초본이고, 잎은 거치가 없으나 엽신 윗부분이 다소 불규칙하며, 원두 또는 둔두이고, 엽액에 주아를 만드는데 비해서 본 종은 포복경을 갖는 다년생 초본이며, 잎은 거치가 없고 요두이며, 엽액에서 주아를 만들지 않는 점에서 다르다. 또한 땅채송화는 모든 잎은 원주상 또는 다소 편평한 선형에서 좁은 장타원형인데 비해서 이 종은 잎이 뚜렷하게 편평하고, 꽃이 피지 않는 줄기의 잎은 주걱형이라는 점에서 다르다.
