摘要/Abstract

摘要： 利用光学显微镜和扫描电镜对21种珍珠菜属植物叶表皮纹饰特征进行了研究。根据叶表皮外壁纹饰特征，可以明显的划分为两种类型，即黑腺珍珠菜型和细梗香草型。这两种类型与以雄蕊群的构造为主要依据的属下分类系统的对应关系不密切，表明叶表皮纹饰特征在亚属级水平上分类学意义不大。但该属植物叶腺体的有无，颜色和分布以及叶表皮纹饰特征在种内相当稳定，种间差异较大，在种级水平上具有重要的分类学意义。

Abstract: The microcharacteristics of leaf surface in Lysimachia were investigated by using light microscope (LM) and scanning electron microscope (SEM). Based on the features of leaf surface, those plants were obviously classified into two types, heterogenea-type and capillipes-type. The features of leaf, such as the presence or absence of the glands, the color and distribution of the glands, and the ornamentation of adaxial side, are quite constant at intraspecific level, but remarkably varied at interspecific level, which might have significant taxonomic value for species identification. In the 21 investigated species, 1 species was from Subgen. Idiophyton, 11 species from Subgen. Lysimachia, and 9 species from Subgen. Palladia. Since 2 types of leaf surface structure were found both in Subgen. Lysimachia and Subgen. Palladia, they could not be used as the characters to define subgenus.

Key words: Lysimachia, microcharacteristics of leaf surface, systematic implication
