THE CLASSIFICATION AND DISTRIBUTION OF THE GENUS FLEMINGIA ROXB.EX AIT.IN CHINA

The Flemingia Roxb. ex Ait. was founded in 1812. There are about 39 species. They are grouped into five sections.There are 16 species and one variety in China. They are situated in southwestern part of this country at between latitude 18°to 30°N. and longitude 98°to 121°E. China is very rich in species of Flemingia as compared with neighbouring countries such as India 18 species, Burma 16 species, Thailand 11 species, Laos 10 species, Vietnam 8 species, Bhutan 1 species, Bangladesh 3 species, Cambodge 3 species, Nepal 5 species. In the present paper, the taxonomy and distribution and evolutionary trends of some important morphological characters are discussed. According to the distribution of this genus, the author suggests that the centre of distribution of this genus be in southwestern Yunnan of China, and maybe it is the centre of origin too.
