臺灣石松類植物補遺（一）：新紀錄種琉球卷柏（卷柏科）

Supplements to the Lycophytes in Taiwan (I): A newly Recorded Species Selaginella lutchuensis Koidz. (Selaginellaceae)

本文新紀錄一種產於臺灣東部之石松類（lycophytes）植物－琉球卷柏（Selaginella lutchuensis Koidz.）。此物種可藉其轉置的孢子囊穗、營養葉腹葉（側葉）葉片先端長尾狀與背葉（中葉）具有顯著的白色軟骨質邊緣等特徵，而與臺灣產其他種類區分。本文提供其分類描述、圖片、分布資訊，以及其與形態近似種類之檢索表。

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.
