抄録

Summary: In Japan, Spiranthes sinensis Ames var. australis(R. Br. )H. Hara et Kitam. ex Kitam. has been known to show variations in the flowering time and plant size. To evaluate the validity of the seasonally differentiated groups and a dwarf form of the species, which is endemic to Yakushima Island, Japan, molecular variations were examined by analyzing nuclear and plastid DNA loci. As a result, above-mentioned variations were to be treated as the rank of forms. Moreover, some unexpected polymorphisms were found. Namely, Japanese and Malaysian S. sinensis var. australis differed significantly in the DNA sequences, suggesting that this variety may not be one biological species. On the other hand, two major groups were recognized among individuals examined, having geological border in Kyushu Island. These data strongly suggested requirement of re-examination of this species, that is widely distributed in eastern Asia and Australia.
