 Camps III, 2500 ft., and VI h, 3900 ft. 



Perhaps nearest to D. gracilentum, Schlechter, but with a very different lip, more 

 resembling that of F>. crenulatum, J. J. Sm., from the latter distinguished by much 

 larger petals and sepals. The apices of the sepals and petals and the tip of the mentum 

 are pink.

I have little doubt that this is the species intended by Smith, and based on a plant of 

 unknown origin in Hort. Buitenzorg; but if so, the figure above quoted is a very poor 

 one.
