摘要

Polystichum otomasui Sa. Kurata, which had been regarded as an endemic fern to Japan, was discovered in the Wuyi Mountains, Fujian Province, South East China. Cytological investigations confirmed that the new collections were sexual diploids with a chromosome number of 2n = 82 (x = 41)and there were 64 spores per sporangium. These morphological data (including spore perispores) accorded with the characteristics of the Japanese Polystichum otomasui.
