台灣耳蕨屬植物之訂正

Abstract

台灣產耳蕨屬植物，經筆者研究之結果，共?二十六種及二變種，其中包括一新記錄-P.inaense Tagawa,及一新階級P.obliquum var.formosanum. 本文係就本屬植物之外部形態詳細觀察之，並採取新鮮材料作葉柄及葉片之解剖。比較其差異以作?分類之依據；以掃描式電子顯微鏡觀察表面之凸起，發現有膠片指壓法或指甲油印模法所觀察的花紋實?角質層表面之起伏所形成。 鱗片是本屬植物分類上之極佳特徵，可據此區分類似的種類。

An intensive study was made of the genus Polystichum of Taiwan which shows that there are 26 species & 2 varieties,a new record species P.inaense Tagawa & a new status P.obliquam var.formosanum,are included. This paper describes a classification based on a close examination of all characteristics;including;anatomy of stipes ,leaves blades ,and SEM photography of the surface of the blades. Scales are good taxonomic characters for this group of ferns.
