摘要/Abstract

摘要： 本文对国产省沽油科 Staphyleaceae 4属植物叶的解剖结构进行了详细的比较研究。结果表明, 叶解剖结构特征在属间的区别较明显, 特别是瘿椒树属 Tapiscia 有着几乎与其他三属截然不同的独特性状。根据已有的孢粉学, 花、节及木材的解剖等方面的资料, 我们支持Тахтаджян(1987)将瘿椒树亚科分出而建立瘿椒树科 Tapisciaceae 的观点。瘿椒树属为我国特有属, 根据我们对采自不同产地的材料观察, 居群间的差异很小, 其可能仍为一单种属。

Abstract: A comprehensive comparative anatomical study of 10 species in four genera of Staphyleaceae in China was conducted to clarify the taxonomy within the family.The variable foliar anatomical features that are often diagnostic at the generic or species level include the occurrence of mucila-ginous epidermal cells, cuticle ornamentation, triehome, type of mature stomatal pattern, presence or absence and type of vein sheathing, outline of midrib vascular bundle on a cross section, type of venation, andto-oth morphology and vascularization.Especially, Tapiscia is specific in almost all organs and tissues.We support that Тахтаджян(1987) erect Tapisciaceae.There are few' differences in varying population of Tapiscia native in China, so we regard that it would be a monotypic genus.
