    Abstract: Wangcang Provincial Forest Park is located in north Wangcang County, Sichuan Province, and between 106°19'15"~106°25'42"E, 32°32'23"~32°36'25"N. There were 980 species of seed plants, belonging to 112 families, 498 genera, and the major were Oligotypic families (73 families,accounting for 65.18% of the total) and Monotypic genera (268 genera,accounting for 53.82% of the total) among which gymnodperms had 5 families, 13 genera, 18 species, and angiosperms had 107 families, 485 genera, 962 species. The floristic elements of genera and families were composed of 15 types and 11 types of Chinese seed plants. At the family level, the major were the Tropical element (46 families,accounting for 41.07% of the total). At the genera level, the major were the Temperate element (282 genera,accounting for 56.63% of the total) and Tropical element (150 genera,accounting for 30.12% of the total). The element of endemic to China had 19 genera (accounting for 3.82% of the total). Moreover, 9 species in Wangcang Provincial Forest Park were listed in the national protection plant categories, such as Taxus chinensis.
