초록

Huperzia lucidula (Michaux) Trevis.의 동북아시아 집단 및 북미 집단을 대상으로 외부형태와 포자형태를 비교한 결과 잎의 형태, 엽연부, 잎에서의 기공의 분포 및 포자의 형태에 있어서 뚜렷히 구분되었다. 따라서, 동북아시아 집단을 북미 지역의 H. lucidula와는 독립된 종 H. asiatica (Ching) B.-Y. Sun and J. Lim으로 분리, 승격하였다. 또한, H. serrata (Thunb.) Trevis.와 동일 종 또는 종내 분류군으로 인식되어 오던 H. javanica (Sw.) C. Yang은 영양엽에서 엽병의 발달 유무, 엽연 거치의 수 그리고 무성아가지의 중앙 열편 모양으로 별개의 종으로 처리하는 견해를 지지하였다.

A comparison of the external morphology and spores clearly distinguished Huperzia lucidula (Michaux) Trevis. in northeast Asia and North America in terms of leaf shape, leaf margin, distribution of stomata on leaves, and spore shape. Therefore, the northeast Asian plants should be treated as a separate species, H. asiatica (Ching) B.-Y. Sun & J. Lim. In addition, we believe that H. javanica (Sw.) C. Yang, regarded as conspecific or infraspecific with H. serrata (Thunb.) Trevis., is a distinct species based on the presence of a leaf petiole and serrated leaf margins, and the shape of the gemmiferous branchlets.
