The spore mother cells of six species of Chinese homosporous ferns have been examined, among them the chromosome numbers of five species, Adiantum capillus-junonis
Rupr. (n= 30), Ctenitis rhodolepis (Clarke) Ching (n = 41), Cyclogramma flexilis
(Christ) Tagawa (n = 68), Leptogramma scallani (Christ) Ching (n = 36) and Vandenboschia auriculata (B1.) Copel. (n=36), from Emei Shan (Omei) Sichuan province
are recorded for the first time. The chromosome number n=68 from the species
Cyclogramma flexilis suggests that the base number for this genus is 34. Another
species, Athyrium brevifrons Nakai from Wuling Shah Beijing (Peking) has a gameticchromosome number n=40, as already reported by K. Mitui and H. Hirabayashi.
