臺灣的兩個新紀錄蕨類植物

Two Taxa of Ferns Newly Recorded to Taiwan

本文報導臺灣新紀錄的兩種蕨類植物－－毛軸過溝菜蕨（Diplazium esculentum （Retz.） Sw. var. pubescens （Link） Tardieu et C.Chr.）及棱脈蕨（Schellolepis persicifolia （Desv.） Pic.Serm.）。二者在臺灣的族群相當稀少，推測應係相對於各自的分布範圍而言，它們俱屬邊緣分布之故。根據國際自然保育聯盟（IUCN）的評估準則，二者在臺灣的保育等級分別列為瀕臨滅絕及嚴重瀕臨滅絕。

This paper describes the ferns Diplazium esculentum (Retz.) Sw. var. pubescens (Link) Tardieu et C. Chr., and Schellolepis persicifolia (Desv.) Pic.Serm. as newly recorded taxa to Taiwan. They are very rare possibly due to the fact that Taiwan is the northeastern marginal range of their distribution. According to the IUCN Red List criteria, their rare status in Taiwan was categorized as EN for D. esculentum var. pubescens and CR for S. persicifolia.
