The distribution of Pteris wulaiensis in Japan was reassessed based on herbarium specimens, and its distinguishing characters from P. oshimensis var. oshimensis were revised and improved. A total of 47 specimens of P. wulaiensis were identified and the localities extend to four prefectures (Wakayama, Nagasaki, Miyazaki and Kagoshima). In Japan, Pteris wulaiensis has been repeatedly collected in southern Kyushu, but apparently rare in Kii Peninsula (Wakayama Prefecture) and in Fukuejima Island off the west coast of Kyushu (Nagasaki Prefecture).
