LATER 
Common Name The Small Point Pteroceras [refers to the small spur at the lip base]
Flower Size .72" [1.8 cm]
Found in the Andaman Islands as a mini-miniature to miniature sized, hot to warm growing epiphyte with a pendulous stem carrying fleshy-coriaceous, ligulate, apically unequally bilobed, cuneate below into the base leaves that blooms in the later spring on an axillary, as long as the leaf, 2 to 3" [5 to 7.5 cm] long, thin, red spotted, simultaneously 7 to 8 flowered inflorescence carrying fragrant flowers.
CAUTION The 2 photos from Yunnan province of China appear to be this species and I am not aware of other Pteroceras with the thin point at the apex of the lip. It is found at 1200 to 1300 meters vs under 700 meters and blooms in the later summer vs the later spring. I am not sure that we are dealing with the same species or something new. Dr Mathew's photo does not give enough detail to see if the have the same lip structure, but otherwise they are very similar.
