STUDIES ON THE SEED PLANTS FLORA OF TALSHAN MOUNTAIN IN SHANDONG PROVINCE

Taishan mountain is located in central Shandong Province.There are 757 species seed plants belonging to 407 genera and 100 families (3 sp.of 3 gen.among 2 fam.of gymnosperms and 754 sp.of 404 gen.among 98 fam.of angiosperms) in this flora.In the 407 genera, there are 11 world monotypic genera and 40 world oligotypic ones, which make up 12.5% of the total.Most of them are phylogenetically ancient or primitive.This means the seed plants flora of Taishan mountain is characteristically of ancient origin.According to Prof.C.Y.Wu’s theory on the areal-types of the genera of China’s seed plants flora, all the 407 genera in this flora can be classified to 15 types, mainly comosing of North Temperate(34.5%),Pantropic(19.1%),Old World Temperate(14.3%)and East Asia(10.1%).The genera of temperate areal-types make up 72.2%,taking a predominated position, while those of tropical ones only acount for 27.8%,which shows that the seed plants flora of Taishan mountain is of a temperate feature,and has something with tropical flora.
