Abstract

Pteris kawabatae Sa. Kurata was regarded as endemic to Japan. We here report its new distribution in China, Taiwan, and Vietnam. We also re-circumscribe P. arisanensis as an independent species and propose its Chinese name herein. A key is provided to compare those morphologically similar Pteris species in Taiwan, including P. arisanensis, P. biaurita, P. fauriei, P. linearis, P. kawabatae and P. wulaiensis.

中文摘要

無柄鳳尾蕨過去被認為是日本特有種，本文報導了本種在大陸、台灣和越南的新分布；另確認 P. arisanensis 為一獨立的種，並建議其中文名稱為「阿里山鳳尾蕨」。本文並提供檢索表，比較幾種形態相似的台灣產鳳尾蕨屬物種，包括阿里山鳳尾蕨、弧脈鳳尾蕨、傅氏鳳尾蕨、三角脈鳳尾蕨、無柄鳳尾蕨與烏來鳳尾蕨等。
