|摘要||A cytotaxonomic study was made of 90 fem species of Yunnan, southwestern China, based on collections from northwestern, central, and southwestern Yunnan and a few Cheng's collections. The results verified most of the formerly reported basic chromosome numbers of Chinese genera, and recorded for the first time the basic numbers of Gymnogrammitis and Sorolepidium and Chinese members of several other genera. Cytotaxonomy of some problematical genera was discussed. Biogeographical relationships between Japanese, Chinese, and Himalayan ferns were compared with special reference to local cyto-reproductive variations in Coniogramme, Deparia, Onychium, and Pteris cretica. The present evidence indicates that most triploid species examined are agamosporous, as general in filicalean ferns, and also suggests the sexual 32-spored sporogenesis in Hypodematium crenatum and Sorolepidium graciale as in Lindsaeaceae.|
