Bulbophyllum brevipedunculatum

This newly described species is native to eastern Taiwan. It occurs at elevations of 1300-1800 m. 

This species prefers cool conditions, bright diffused light, and should be kept drier in the winter.

It is very rare in cultivation. 

Some consider this a synonym of Bulbophyllum albociliatium, however, Plants of the World (Kew) considers this a distinct species. The drawing below is from the Flora of China description.
