摘 要 ：利用光学显微镜及电子显微镜对石杉科（Huperziaceae）石杉属（Huperzia）5种植物：蛇足石杉(Huperzia serrata(Thunb. ex Murray) Trev.)、皱边石杉(Huperzia crispata(Ching) Ching.)、四川石杉(Huperzia sutchueniana(Herter)Ching.)、南岭石杉(Huperzia nanlingensis)和长柄石杉(Huperzia javaensis)的叶片微结构进行观察与研究。结果显示：这5种石杉均无叶表面附属物，具无规则四细胞型和不规则型两种类型的气孔，不规则型为主要气孔类型。这5种石杉在气孔组成上具多型现象，气孔多为下生型，分布方式及大小多样；叶表皮细胞在不同类型中有大小差异但均呈不规则状，表皮细胞垂周壁呈波纹状（深波状、浅波状）。上述研究结果为石杉属植物的进一步分类与研究提供依据。

Abstract:We studied the microscopic characters of the leaves of Huperzia serrata(Thunb. ex Murray) Trev, Huperzia crispata(Ching) Ching, Huperzia sutchueniana(Herter) Ching, Huperzia nanlingensis and Huperzia javaensis. with optical microscope and electron microscope. There are no trichome in the leaves of five species. We observed two types of stomatal apparatu(anomotetracytic and anomocytic) in the leaves of the five species. Anomocytic type is a typical stomata of these five species. The stomatal apparatus have multi-type phenomena, most of the stamatal are hypostomatic types, while their distributive modes and size also varies. There are obvious differences of leaf epidermal cell size and shape in five kinds of Huperzia plant, and the anticlinal walls of the epidermal cell are corrugated(undulate and sinuate).
