Abstract

A new species, Pseudostellaria baekdusanensis M. Kim (Caryophyllaceae), has been named and described from Mt. Baekdu of the Korean peninsula. Pseudostellaria baekdusanensis shares several characteristics (same size leaves, axillary or terminal flowers, emaginate petals, etc.) with its related species P. japonica (Korshinsky) Pax. It is, however, distinct from P. japonica which have large plant (25-35 cm), leaf blade margins and midveins with long hairs, shallow emaginate petal apex, (2) 3 styles, and cleistogamic flowers by having small plants (9-13 cm), leaf blade basal margins with long hairs, deep emaginate petal apex, 2 styles, and non-cleistogamic flowers.

백두산에서 개별꽃속의 신종인 애기개별꽃(Pseudostellaria baekdusanensis M. Kim)을 새로이 발견하여 기재하였다. 애기개별꽃은 잎의 크기가 비슷하며 꽃은 줄기 끝에 액생 또는 정생하고 꽃잎은 요두인 특징을 가져 긴개별꽃(P. japonica (Korshinsky) Pax)과 유사하다. 그러나 애기개별꽃은 식물체가 9-13 cm로 소형이고 1줄의 털이 줄기에 있고 엽신 가장자리 기부에만 긴 털이 있으며 꽃잎은 깊은 요두형이고 화주는 2개이며 폐쇄화가 식물체에 달리지 않는다. 반면에 긴개별꽃은 식물체는 25-35 cm로 대형이고 1-2줄의 털이 줄기에 있고 엽신 가장자리와 이면 중륵에 긴 털이 밀생하며 꽃잎은 얕은 요두형이고 화주는 (2) 3개이며 폐쇄화가 엽액에 달린다는 점에서 뚜렷하게 차이를 보인다.
