초록

국화과 상치족에 속하는 서양개보리뺑이(Lapsana communis) 내의 6아종과 개보리뺑이속 (Lapsanastrum) 4종에 대해 과피의 해부학적 구조를 조사하였다. 그 결과, 개보리뺑이속은 서양개보리뺑이와 외과피의 털의 유무, costa의 모양, 종피의 비후 등 몇 가지 형질에서 차이가 나타났다. 게다가 서양개보리뺑이속은 costae와 intercostae에 sclerenchymatous cell이 없는 반면에 개보리뺑이속은 sclerenchymatous cell로 이루어져 있다. 과실벽 구조에서의 차이는 명백하게 개보리뺑이속이 광의의 서양개보리뺑이속에서 분리됨을 지지한다.

The mature fruit wall structures were investigated in Lapsana communis, its six subspecies and the four species of Lapsanastrum (Asteraceae; Lactuceae). Lapsanastrum differs from Lapsana communis in some features: two or three protrudent costae verse equally developed costae, hairly versus glabrous exocarp, respectively. Moreover, Lapsana has no sclerenchymatous‐fiber cells in mesocarp, while Lapsanastrum has sclerenchymatous fiber cells. The differences in fruit wall structure between Lapsana and Lapsanastrum obviously support the separation of Lapsanastrum from Lapsana s. lat.
