六种国产大帽藓属植物孢蒴表皮的观察

A Survey on the Capsule Epidermises of Six Species of Genus Encalypta Hedwig

〕通过对尖叶大帽藓（ＥｎｃａｌｙｐｔａｒｈａｂｄｏｃａｒｐａＳｃｈｗａｅｇｒ．），裂瓣大帽藓（Ｅ．ｃｉｌｉａｔａＨｅｄｗ．），高山大帽藓（Ｅ．ａｌｐｉｎａＳｍｉｔｈ．），西藏大帽藓（Ｅ．ｔｉｂｅｔａｎａＭｉｔ．），西伯利亚大帽藓〔Ｅ．ｓｉｂｉｒｉｃａ（Ｗｅｉｎｍａｎ）Ｗａｒｎｓｔ．〕，剑叶大帽藓（Ｅ．ｓｐａｔｈｕｌａｔａＣ．Ｍｕｅｌ．）孢蒴表皮的观察表明：６种植物孢蒴表皮的气孔形态和分布，表皮细胞排列与细胞壁增厚的方式各有显著的区别特征，可以作为种间分类的依据，并据此编写了分种检索表。

In this paper the capsule epidermises of Encalypta rhabdocarpa Schwaegr., E.ciliata Hedw., E.sibirica (Weinman.)Warnst., E.tibetana Mitt., E.spathulata C.Muell., E.alpina Smith.are observed.The result show that the six species is obviously distinguished in the morphological characters and distribution of the stomata,the arrangement of the epidermal cells,and the way that cell walls thichen.And the species can be classified by these characteristics.A key to the six species is also given.
