Native of mid-Yunnan at comparatively low altitudes; discovered by Forrest in 1913 and 1914 near the border between Yunnan and Burma, north-west of Tengyueh, and above the Yangpi valley, south-west of the Tali range. The date of introduction is uncertain, but the truss depicted in the Botanical Magazine is from a plant that flowered in E. J. P. Magor’s garden at Lamellen, Cornwall, in April 1929. The true species appears to be very rare in cultivation.
