Abstract: Based on field investigation and data access, this paper made a the list of national key protected wild plants and analyzed the species composition and flora of the national key protected wild plants in East China. Results showed that there were 94 species of national key protected wild plants belonged to 69 genera and 42 families, among which there were 60 species of angiosperms belonged to 49 genera and 30 families, 22 species of gymnosperms belonged to 14 genera and 7 families, and 12 species of ferns belonged to 6 genera and 5 families. The origin of national key protected wild plants was ancient and the composition was complex, and endemic in this area was obvious. Tropical and temperate elements were dominant in the flora, which took up an obvious characteristic of transition. The analysis of flora richness and similarity indicated that the species in Jiangxi, Zhejiang, Fujian and Anhui were relatively abundant and closely related to each other, and that the species in Jiangsu and Shanghai were scarce, and meanwhile they were less related to the other provinces. The species of national key protected wild plants in Shandong was least, without the same families, genera, species as other provinces. The aim of the research was to analyze flora of the national key protected wild plants, in order to provide references for reasonable conservation and effectively use of the key protection wild plants in East China.

Key words: East China, national key protected plant, wild plant, floristic characteristics
