本文報告臺灣產蹄蓋蕨科新紀錄種：密腺蹄蓋蕨。本種過去多被錯誤鑑定為宿蹄蓋蕨，其植株密被單細胞腺毛為其主要區別特徵，其羽片型態亦異於宿蹄蓋蕨。本文提供密腺蹄蓋蕨之型態描述、手繪圖、毛被物以及生態照片，並於文中描述該種與其他相近種之型態差異。

Athyrium puncticaule is recorded for the first time from Taiwan. Most specimens of this species deposited in Taiwanese herbaria have been misidentified as Athyrium anisopterum. It can be distinguishable by densely covered unicellular hairs on the fronds and morphology of pinnae. The authors present a description, illustration, photographs and notes about this new addition to the Taiwanese fern flora and its distinction from other species.
