Lindley (Gen. Sp. Orchid. Pl. 16. 1830) misapplied the name Oberonia myosurus (Forster) Lindley to this species when judging Wallich 1947 to be conspecific with the Pacific island Epidendrum myosurus Forster, which is now referred to Phreatia myosurus (Forster) Ames (see Seidenfaden, Opera Bot. 124: 19. 1995).
