Bornéo: Soengei Deiigei.(Exp. A. W. Nieuwenhuis 1896— '97, Jaher i 

 II. 792). 



Near E. monostachya Lndl., that is to say the plant which I hâve 

 liitherto regardée! to be tliis species. but differing by the very narrow leaves 

 and the unguiculate midh)be. 



1 suppose tliat the basai callus of the lip is trifid as in the allied 

 species, though 1 did not see the latéral lobes, owing probably to the single 

 flower being very much conipressed.
