Abundant in some places, growing on old stumps or on the 
ground in dry woods. This flowers all the year round. It has 
dull yellowish flowers with a brown blotch on the hp; they 
have but little scent. I have seen a small Rhynchophorous 
beetle creeping about among the flowers with the pollen masses, 
on its head.

In Curtis’s plant I find the lateral lobes of the lip smaller
