Abstract

We report Vallisneria spinulosa S. Z. Yan (Hydrocharitaceae) as an unrecorded species from the flora of Korea. This aquatic vascular plant occurs in reservoirs, streams, and ditches at Changnyeong, Changwon, and Gimhae which belong to Nakdong river basin. Vallisneria spinulosa is distinguishable from V. natans (Lour.) Hara already known to Korean flora by the presence of turion and hairs at base of stamen, adnation between pistil and staminodia, the number of stamen, and shape of fruit and seed. V. spinulosa is similar to V. desnseserrulata Makino in the viewpoint of distribution (Japan and southern China), but V. spinulosa has three to five epidermal wings on the surface of seed.

낙동강 수계인 경남의 창녕, 창원, 김해 일대의 저수지, 하천, 수로에서 채집한 자라풀과 (Hydrocharitaceae)의 낙동나사말 (Vallisneria spinulosa S. Z. Yan)을 국내 미기록 식물로 보고한다. 본 분류군은 기존에 보고되어 있는 나사말 [Vallisneria natans (Lour.) Hara]과 동아의 유무, 수술의 수, 웅예 기부의 털의 유무, 암술과 가웅예의 부착상태, 열매와 종자의 모양으로 구별되며, 일본과 중국 남부에 분포하는 V. denseserrulata Makino와 유사하지만 종자에 3 - 5 개의 막질 날개가 있다는 점에서 구분된다.
