On trees or rocks in forests or along valleys; 500-2200 m. Guangxi, Hainan, SW Sichuan, SE Xizang, SE Yunnan [Thailand, Vietnam].
L.bootanensis Griff.extremely close to L.bootanensis Griff., the only difference is that the flower is larger, the sepals are 1-1.1 cm long and the lips are 1 cm wide, while the sepals are 3.5-6 mm long and the lips are 2.5-5.5 mm wide. G. Seidenfaden ( 1976 ) had thought that there were other differences, but could not be identified on the specimens we saw. Whether these two should be merged or reduced to variants remains to be further studied. |
