Epiphytic on tree trunks in forests; 200-2000 m. S Fujian, Guangxi, Hainan, Hong Kong, SE Xizang, W to SE Yunnan [Bhutan, Cambodia, NE India, Laos, Myanmar, Nepal, Thailand, Vietnam].
The leaf shape and flower color of this species vary. The leaves of plants distributed in northwestern Yunnan are semi-cylindrical, and those in other regions are flat. The color of flowers in the same area also varies slightly, but their flowers are completely consistent in shape and structure. Therefore, we agree that some authors regard them as a kind.
