| 摘 要： | 华夏植物群的起源问题，国内外有不同认识。笔者根据研究工作的成果并参考大量中外文献资料，提出华夏植物群起源于早石炭世晚期（维宪期至纳缕尔Ａ期）的新认识，自中石炭世￣①早期（纳缪尔８－Ｃ期）已成为独特的植物群；同时认为它并非由欧美植物群发展而来，二者均源于拟鳞木植物群，分别在各自所处的环境中平行演化而形成。

| Abstract: | The Cathaysia Flora is one of the four late Paleozoic noras found all overthe world.It is distributed mainly in China and Korea,but also in Japan,Laos,Thailandand lndonesia etc.. There are different Theories at home and abroad about its origin.Resolfing from the author'research and the Chinese and foreign documents consulted,the present paper suggests a new idea about the origin of the Cathaysia Flora i.e,itoriginated in late early Carboniferotus(Visean-Namurian A),and became an independentflora from early middle Carboniferous(Namurian B-C;It did not develop from theEuramerica FIora,but from the Lepidodendropsis Flord and was formed by parallelism inrespectlve envlonments. |
