摘    要:用扫描电镜和光学显微镜对竹思]簩竹属(Schizostachyum Nees)7个种,及其近缘的梨竹属(Melocanna Trin.)、泡竹属(Pseudostachyum Munro)、薄竹属(Lepzocanna Chia et H.L.Fung)各1个种以及空竹属(Cephalostachyum Munro)6个种的叶表皮微形态特征进行了观察。结果表明竹叶下表皮乳突的形状和在气孔器上及周围的排列式样在这5个属中各有不同,具有重要的分类学和系统学价值。同时我们的结果不支持广义的笃竹属;而梨竹属、空竹属和泡竹属则被支持独立成属。另外,薄竹(Leptocanna chinensis)和红毛竹思]簩竹(Schizostachyum sanguineum)的叶表皮微形态特征非常接近空竹属;香糯竹(Cephalostachyum pergracile)和金毛空竹(C.virgatum)的叶表皮微形态特征则十分接近竹思]簩竹属。

关 键 词:[竹思]簩竹属  梨竹亚族  竹亚科  叶表皮  微形态  分类学

Abstract:Micromorphological characters of leaf epidermis of 16 published species from Schizostachyum Nees and its allies (including Melocanna Trin.,Pseudostachyum Munro,Leptocanna Chia et H.L.Fung and Cephalostachyum Munro) were examined by both light and scanning electron microscopies.The results indicated that the papillae forms and distributional patterns on the abaxial surface were taxonomically informative at the generic level.The characters of papillae did not support Schizostachyum sensu lato;meanwhile,it was supported that Melocanna,Pseudostachyum and Cephalostachyum were better to be treated as separate genera respectively.Furthermore,it seemed to be more appropriate to place Leptocanna chinensis and Schizostachyum sanguineum in Cephalostachyum;and to place Cephalostachyum pergracile and C.virgatum in Schizostachyum.
Keywords:Schizostachyum  Melocanninae  Bambusideae  Leaf epidermis  Micromorphology  Taxonomy
