Abstract

A new speices, Potentilla gageodoensis M. Kim found in Is. Gageodo, Jeollanamdo Province, Korea, is firstly named and described. This species is similar to its related species P. fragarioides in having several characteristics like pinnately compound leaves, pubescent leaf blades and leaf petioles, different leaflets size, absent stolons, etc., but is distinct from P. fragarioides which has thin leaf textures, 7-13 leaflets, elliptic terminal leaflets, small petal size, and ciliate leaflet margin by having thick leaf textures, 5 leaflets, broadly ovate terminal leaflets, large petal size, and densely white ciliate leaflet margin.

전남 가거도에서 양지꽃속의 신종인 가거양지꽃(Potentilla gageodoensis M. Kim)을 새로이 발견하여 기재하였다. 가거양지꽃은 잎은 우상복엽이며 엽신과 엽병에 털이 있고 3개의 정소엽이 측소엽보다 크며 포복경이 없어 양지꽃과 유사하다. 그러나 가거양지꽃은 잎은 두껍고 근생엽은 흔히 5장의 소엽으로 이루어졌으며 정소엽은 광난형이고 꽃잎이 크며 소엽 가장자리에 흰털이 밀생해서 흰색 테두리가 있는 것처럼 보인다. 반면에, 양지꽃은 잎은 얇고 근생엽은 흔히 7-13장의 소엽으로 이루어졌으며 정소엽은 타원형이고 꽃잎이 작으며 소엽 가장자리에 흰털이 적은 점에서 두 종이 뚜렷하게 차이가 난다.
