| 摘 要： | 广东省种子植物区系中分布有中国特有属７５属，约含１２８种，隶属于４０科；科属种占中国同类的比例分别为：４５．４％，２３．４％和１７．０％。其中含有丰富的古特有，新特有及地区特有属，它们都是广东亚热带植物区系的特征属；而且在西南一桂东南形成了一个中国特有现象中心。根据这些特有成分的地理分布特点，结合广东及邻近地区古老的区系发展历史来进行分析，广东无疑是中国植物区系或华夏植物区系发生的关键地区之一。

| Abstract: | Genera endemic to China in the spermatophyte flora of Guangdong province consistedof 40 families 75 genera and about 128 species;the percentages possessing the same group of Chi-na were:45.4% of families,23.4% of genera,and 17.0%of species.Among them containedplenty of the palaeoendemic genera,neoendemic genera,local endemic genera,and so on,ofwhich all were genera characteristic of Guangdong flora and formed a centre of endemism to Chi-na in Southwest Guangdong to Southeast Guangxi.Based on the analysis of the distribution ofthose endemic elements and ancient floristic histories in Guangdong province and its neighbour-hood ,Guangdong was one of the key regions of the orig ins of the Chinese flora or the Cathaysianflora. |
