摘 要 ：利用光学显微镜对云南20种不同科、属的蕨类植物的叶表皮形态进行了观察和研究。结果表明：它们的叶片表面存在不同的附属物，而有的种类无附属物；20种蕨类植物共具8种气孔器类型(极细胞型、腋下细胞型、辐射状细胞型、双不等细胞型、无规则四细胞型、共环极细胞型、聚腋下细胞型和不规则型), 它们在气孔器组成上具多型现象，气孔均为下生型,分布方式及大小多样；叶表皮细胞的微形态在科属间表现出一定的差异，主要有不规则型、多边型或规则条状，表皮细胞垂周壁呈波纹状、深波状或波浪状。上述研究结果为蕨类植物的系统分类及演化提供依据。

Abstract:Epidermal micromorphology of 20 species ferns leaves from different families and genera in Yunnan were observed by optical microscope. The results showed that: different appendages exist in different leaves surface, some species have no appendage. There are eight stomatal apparatus types: polocytic, axillocytic, aotinocytic, diaisocytic, anomotetracytic, copolocytic, coaxillocytic and anomocytic types. The stomatal apparatus have multi-type phenomena, all the stomata are hypostomatic types, while their distributive modes and sizes also varies. The leaf epidermal cell micromorphology from different genera and families show certain differences, basically have irregular type, multilateral type or regular strip type. The leaf epidermal cell anticlinal walls are mainly corrugated, deep wavy or wavy. The results in this study provide basic references for systematics and evolution of ferns.
