Cytotaxonomic study of the fern genus Lepisorus (Polypodiaceae) from China
A cytotaxonomic study is conducted for Lepisorus from eastern, southern, and southwestern China, involving 120 samples of about 26 species in seven sections. The chromosome numbers of 10 species are reported for the first time. The basic chromosome numbers, x = 19 and x = 22 discovered in L. cespitosus and L. lineariformis, respectively, are found to be new base numbers in Lepisorus. The taxonomic implications of the chromosome information of some species and the evolution of chromosomes in the genus are discussed.
