摘要
通过在光镜下对云南境内12种莲座蕨科植物的叶表皮细胞进行观察研究,发现:①气孔类型可作为莲座蕨属和原始莲座蕨属分类依据;②气孔密度可作为分种依据.叶表皮细胞结构特征具有重要的分类学及系统学意义,其中莲座蕨科12种植物的气孔器密度、11种植物叶表皮细胞结构解剖照片均属首次报道.
The morphological characters of the leaf epidermis of 12 species （Angiopteridaceae） from Yunnan were studied through a light microscope. The stoma densities of 12 species and the anatomical photoes of the leaf epidermal cells of 11 species were reported for the first time. It was found that each species had a special stoma density, and the stoma types were different between Angiopteris fokiensis Hieron and Archangiopteris henryi Christ et Gies,which could be considered as key characters to the genera and species of Angiopteridaeeae.
