华中植物区的特有种子植物

华中植物区系具有比中国其它地区更丰富的古老、孑遗和特有成分,被称之为中国植物区系的核心地区.据统计,本区计有土著种子植物210科1280属6390种,其中中国特有科有8科,中国特有属93属.中国特有种4035种.同时,由于本区地质历史古老且地形复杂和封闭,含有大量的地方特有类群,计有华中特有属32属,华中特有种1596种.根据华中区内部在自然条件和区系特性上的差别,华中区可划分为6个亚区.本文将华中区全部的特有种按系统列出.

Notes on Endemic Seed Plants in the Floristic Region of Central China

The floristic region of central China is referred to as the core of the Chinese flora with more archaic,relic and endemic elements than any other places in China. According to the statistics,in this region 6 390 species of native seed plants belonging to 1 280 genera in 210 families are recorded;among them 7-8 families, 92 genera and 4 035 species are Chinese endemic. Moreover, owing to its archaic geological history and complex and isolated topography,the flora of Central China contains a great number of local endemic groups-32 genera and 1 596 species. This area is of special importance to floristic studies of the world,and is may be useful and valuable to some botanical researchers to publish these scientific materials on all the endemic species. On the basis of some internal differences of the natural conditions and the floristic characteristics,this region can be divided into six subregion. Each of endemic species in this region is listed and assigned to its related family,and subregion. These materials will be indispensable to those tho are concerned.
