裸蒴属营养器官的解剖及其分类位置的研究

本文通过对三白草科 saururaceae 裸蒴属 Gymnotheca Decne．  营养器官的解剖和观察，发现该属和三白草属Saururus L.、蕺草属 Houttuynia Thunb. 有明显的区别，而同胡椒科Piperaceae 的齐头绒属 Zippelia Bi．则有许多相似的特征。因此我们认为该属和齐头绒属同为三白草科和胡椒科的中间过渡类型。

A Study on the Anatomy of Vegetative Organs of the Gymnotheca Decne. (Saururaceae) in Relation to Its Systematic Position

The  present  paper  deals  with  the  anatomy of  vegatative organs  of Gymnotheca Decsne. Many significant differences between the genus and the other genera (Saururus L. and Houtuynia Thunb.) of the same family have been discovered in our study. On the contrary, the genus and Zippelia Bl. of the family Piperaceae have many anatomical characteritics in common. The genera Gymnotheca Decne. and Zippelia Bl. are therefore considered intermediate between the families saururaceae and Piperaceae from anatomical point of view.
