中国囊瓣木属和野独活属植物叶形态结构的比较及分类意义

Leaf Form and Structure of Saccopetalum and Miliusa from China and Their Taxonomic Significance

摘要: 对囊瓣木属1种和野独活属4种植物叶形态结构的比较研究表明：囊瓣木和野独活属4种植物的叶表皮形态、表皮细胞形状、表皮细胞内的晶体类型、叶肉组织结构、叶肉中油细胞的分布和密度、主脉维管组织结构等具有很大的相似形。结果同意将囊瓣木属归并于野独活属的观点，并将囊瓣木（Saccopetalum prolificum)组合为囊瓣野独活（Miliusa prolifica)。

Abstract: A more detailed comparative study was carried on the leaf form and structure of Saccopetalum prolificum,Miliusa chunii, M.sinensis,M.tenuistipitata and M.balansae.The results showed that in Saccopetalum prolificum, the leaf form, the shapes of epidermal cells,the types of crystal in epidermis,the structure of mesophyllous tissue,the distribution and density of oil cells,and the pattern of vascular tissue in the midrib and so on were very similar to those in 4 species of Miliusa.Therefore, this surported the viewpoint that the Saccopetalum was reduced to the Miliusa and Saccopetalum prolificum was changed into Miliusa prolifica.
