Bulbophyllum purpurascens sightings in Sarawak

I was on the usual morning run and saw these blooming at the tiny forest preserve in the city. There's no elevation here and the forest is exposed to a lot of human activity. Goes to show that the habitat of this species is quite diverse.

Here's a view of the numerous well established Bulbophyllum purpurascens clumps growing on the tree roots close to the ground. 

The big clump on the left.

Another smaller clump that's shaded, but is still flowering quite happily.
