Tsutsumi and Yukawa (Bull. Natl. Mus. Nat. Sci., Tokyo, B, 34: 89-94. 2008) argue that the name Liparis japonica (Miquel) Maximowicz is actually a synonym of Malaxis monophyllos. The next available name for the "L. japonica" of authors is L. campylostalix. We have not followed Lang and Tsi (in Wu, Fl. Xizang. 5: 842-844. 1987) in separating "L. japonica" (larger plants, entire lip) from L. campylostalix (small plants, entire lip) given that intermediates exist.
