In FRPS (57(3): 51. 1991) this species was treated as Gaultheria pyroloides J. D. Hooker & Thomson ex Miquel (Ann. Mus. Bot. Lugduno-Batavi 1: 30. 1863), which was described from Japan. The name G. miqueliana Takeda is a synonym. Airy Shaw (Bull. Misc. Inform. Kew 1940: 318. 1941) restricted the name G. pyroloides to the Japanese species described by Miquel. Therefore, the Himalayan species described here must be called G. pyrolifolia.
