The East Asiatic genera and endemic genera of the Pteridophytes in China

Xian Chun Zhang

Abstract

China, the largest country in East Aisa, has a pteridoflora of over 2000 species, belonging o about 220 genera in 63 families. There are about 28 East Asiatic genera of Pteridophytes nd 6 genera specifically endemic to China. Most of these genera are oligotypic or monotypic groups. Five distribution patterns of the East Asiatic genera are distinguished, .e., Ⅰ. Sino-Himalayan type, 10 genera ; Ⅱ Sino-Japanese type, 4 genera; Ⅲ. apan-Himalayan type, 6 genera; Ⅳ. Temperate East Asiatic type, 3 genera; and Ⅴ. Tropical ast Asiatic type, 5 genera. The Chinese endemic genera are mainly distributed in southwetern China. The distribution, ecology, taxonomy, and systematics of these genera are discussed.
