About 3100 m. "W China" [NE India, Nepal].

This new record for China is based on E. H. Wilson 4579 (K), collected in W China in July 1904. We do not accept the view of Pearce and Cribb (Orchids Bhutan, 203. 2002) that Liparis nana Rolfe from Vietnam is conspecific because it differs in having an erose, subquadrate lip with a U-shaped callus.
