“华夏植物群”的沿革和应用范围

On the Concept of “Cathaysia Flora” and Its Applied Limit

主要繁盛于东亚石炭二叠纪的华夏植物群（Ｃａｔｈａｙｓｉａｆｌｏｒａ）早已驰名中外，且在地质古生物界始终有着一致认识。在回顾了这一学术用语的沿革及研究现状后指出，不宜将这一名称更改含义后用于指三叠纪以来的有花植物区系。

The Cathaysia flora, which mainly flourished during the Permo-Carboniferous time in East Asia, has been held consistently in geology and palaeontology at home and abroad. About the “Cathaysia flora', as a scientific term, on the bases of reviewing its coures of change and development as well as the current studies situation, the writers of this paper point out that it should be inadvisable to enlarge its meaning to refer the flowering flora that has been developed since Triassic.
