Spiranthes hachijoensis is most morphologically similar to Spiranthes hongkongensis S.Y.Hu & Barretto 1976 but can be distinguished by its glabrous rachis, ovaries, and sepals. Also similar to Spiranthes australis ( R.Br. ) Lindl. 1824 but differs in its papillate (vs. glabrous) basal labellum callosities and glabrous (vs. densely pubescent) rachis, ovaries, and sepals."
