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.

A new species belonging to Lycopodiaceae Mirb. Huperzia Bernh. s.l. is described and illustrated: Huperzia jejuensis B.-Y. Sun & J. Lim. H. jejuensis has been considered conspecific with H. integrifolia (Matsuda) B. ${\emptyset}$llg. ex. Z. Satou, but it is clearly distinguished by the characteristics of linear-lanceolate leaves with parallel margins from the base to the mid-part, minute dentate margins from the mid-part to the end of the leaf, and cuspidate gemma apex. Because the habitat of the new species was confined to Jeju Island, 'jejuensis' was chosen as the specific epithet of the scientific name of the new taxon.
