摘  要：
在光学显微镜和扫描电镜下,观察了南五味子属(Kadsura Kaem pf.ex.Juss.)全属11种,八角属(Illicium Linn.)2种,共108个样品的叶表皮特征。在南五味子属中,叶表皮细胞的形状、叶表皮表面的纹饰、气孔器的形状、气孔极区的形状、表皮毛的有无等性状能用于研究南五味子属种间关系,以及与五味子属(Schisandra Michaux)和八角属之间的关系。在八角目(Illiciales)中发现的一个新分类学性状(叶表皮表面具角质网纹),支持将南五味子属分为离蕊南五味子亚属(Subg.Cosbaea)和南五味子亚属(Subg.Kadsura)。根据叶表皮形态特征,支持将南五味子亚属分为南五味子组(Sect.Kadsura)和肉蕊组(Sect.Sarcocarpon),支持R.M.K.Saunders和林祁对某些种的归并处理。根据与五味子属和八角属叶表皮形态特征的比较,认为这3个属的叶表皮形态特征相似,但南五味子属叶表皮形态比五味子属和八角属的叶表皮形态复杂,不支持将五味子科(Schisandraceae)从八角目(Illiciales)中分出而成立五味子目(Schisandrales)的观点。

摘  要：
The leaf epidermis of 108 samples belonging to Kadsura Kaempf. ex. Juss. (eleven species) and Illicium Linn. (two species) are described using light and scanning electron microscopy. Several characters, such as pattern of epidermal cells, shape of stomatal apparatus, cuticular ornamentations, shape of cuticular intrusions at the polar region of guard cell, hair on epidermis, etc., are constant in some species and variable in others, and thus of considerable taxonomic value for studying the phylogenetic relationships within Kadsura and among Kadsura, Schisandra Michaux and Illicium Linn. A new character, cuticular reticulations that has not been reported previously in the order Illiciales is revealed in the study, which is congruent with the taxonomic assignment of two distinct subgenera (Subg. Cosbaea and Subg. Kadsura) in Kadsura. These characters of leaf epidermis sustain the subdivision of Subg. Kadsura into Sect. Kadsura and Sect. Sarcocarpon, and also support the combinations of some species by R. M. K. Saunders and Q. Lin. Moreover, stomata and other epidermal characters suggest close phylogenetic affinities of Kadsura, Schisandra and Illicium, whereas Kadsura seems more complex than Schisandra and Illicium on the basis of the characters of leaf epidermis. Evidence from leaf epidermis serves as a criterion for negating the separation of Schisandraceae from Illiciales as Schisandrales.
