Abstract

This paper reports a new recorded lycophyte, Selaginella lutchuensis Koidz., collected from eastern Taiwan. This species can be distinguished from other congeners by its resupinate strobili, long-tailed apex of ventral (lateral) trophophyll and distinctly white-callous margin of dorsal (median) one. In the present work, taxonomic description, distribution information, line drawing, and photographs of this newly recorded species are provided. A key is also provided to distinguish the morphologically related species of Taiwan.
