摘要Chromosome numbers and reproductive types of six species of four genera in the Dryopteridaceae, i.e., Leptorumohra, Lithostegia, Phanerophlebiopsis and Cyrtogonellum were investigated. The chromosome numbers were n=41 in Leptorumohra quadripinnata, 2n=164 in Lithostegia foeniculacea, 2n=82 in Phanerophlebiopsis neopodophylla, 'n'= 123, and 2n=123 in Cyrtogonellum fraxinellum, 'n'=123 in C caducum and 2n=123 in C inaequalis, respectively. The chromosome numbers for all the genera but Leptorumohra were reported for the first time. The results indicated that the chromosome base number of all the four genera was x=41, a common number in the Dryopteridaceae. The reproductive type in Cyrtogonellum is apogamous, whereas in the other three genera it is of the sexual reproductive type, which is widely found in ferns.
