檬果樟属的分类与分布兼论这一分布区类型的特征

NOTES ON THE TAXONOMY AND DISTRIBUTION OF THE GENUS CARYODAPHNOPSIS OF LAURACEAE AND TO DISCUSS THE CHARACTERISTICS OF ITS AREA-TYPE

作者在本文中讨论了檬果樟属(Caryodaphnopsis Airy Shaw)的分类和分布。该属约14种,其中7种见于热带亚洲,7种见于热带美洲,其分布属于热带亚洲和热带美洲分布区式样。这一分布区式样的属在我国共有33个,隶属于27科。作者对这一分布区式样的属进行分析,论述这一分布区式样的特征,推测它们大多可能在中生代起源于古南大陆并且主要是第三纪古热带区系成分。

In this paper, the present writers are to discuss the taxonomy and distribution of the genus Caryodaphnopsis Airy Shaw. The whole genus included about 14 species, among them 7 species in tropical Asia and 7 species in tropical America. The area of Caryodaphnopsis Airy Shaw belongs to the area-type of Tropical Asia and Tropical America (or tropical amphi-pacific) , but this area-type had still 32 genera except it in China, they fall into 27 families. According to the characteristics of the distribution of these genera, we may be supposed that they were mostly originated at Gondwana during Mesozoic and they are mainly tertiary palaeo-tropical floristic elements.
