摘要: 利用扫描电镜法、徒手切片法对中国产的2种异蒴藓进行观察分析。分别观察了孢子大小、颜色、叶片和茎的长度和宽度等。结果表明异蒴藓属植物叶片的一些形态学和解剖学性状表现出了金发藓科植物所共有的特征,异蒴藓属在金发藓科中气孔较明显属于进化性状,而孢壁纹饰则属于原始性状。

Abstract: The observation by scanning electron microscope and the comparison of the leaf and stem structure of 2 species of Lyellia were using in it.The spores,leaf and stem were measured.The result show that some of morphology and anatomy of leaves was same as other plant of Polytrichaceae,the stomatal of Lyellia was evolutional,ornamentation of spores was primitive.

Key words: Lyellia crispa, Lyellia platycarpa, electron microscope, morphology
