Asplenium varians is widely distributed in the Sino-Himalayan region and in Africa, but was newly recorded in Japan, where it occurs at two localities approximately 50 km apart in Miyazaki Prefecture, Kyushu. Two interspecific hybrids involving A. varians (i.e., A. anogrammoides × A. varians and A. ×tenuivarians) were also growing at the periphery of the A. varians populations. We confirmed the identity of the hybrids by chloroplast rbcL sequences, chromosome numbers and morphological features.
