Abstract: In this paper the seed plant flora of different life-forms in East Guangdong were studied.Based on statistics and analysis,the results show that:6 life-forms were divided from 2226 species seed plants in E.Guangdong,of which there are 1198 species of woody plants(percentage of the total:53.8%) and 1208 herbs(percentage:46.2%).As to the flora of different life-forms,it is indicated that there are more tropic elements in wood plants than herbs,according to the percentage of tropic element and the representative degree of local flora,the order are trees>woody vines>shrubs>hydrophytes>terrestrial herbs>herb vines.
