Here we describe a new variety of the mycoheterotrophic genus Lecanorchis, L. triloba J. J. Sm. var. clausa Suetsugu & Fukunaga, discovered during a botanical survey in Okinawa Island, Ryukyu Islands, Japan. The new variety resembles Lecanorchis triloba var. triloba due to its densely flowered rachis and small fruits. However, the new variety differs in that it has complete cleistogamous flowers and a nonrecurved and narrowly triangular midlobe of the lip.
