Abstract:

The spore mother cells of six species of Chinese homosporous ferns have been ex-

amined, 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 Vanden-

boschia 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 gametic

chromosome number n=40, as already reported by K. Mitui and H. Hirabayashi.
