Reticulated Bulbophyllum

While coming down from a limestone hill in Sarawak, we stumbled on an interesting orchid on the dryish forest floor .....

This orchid has a very distinctive network marks on the leaves and not surprising, is known by its latin name Bulbophyllum reticulatum.

I have a very free-flowering specimen growing on a fern bark for many years but never once had I suspect it could actually be a ground dweller.
The cluster of flowers somehow remind me of a nestling of small birds - the hinged lips are highly mobile and will rock to and fro with slightest movement.
