Sumatra: East coast, Deli, south west of Bandar Baroe, 1000 m., 

 in forest, on a fallen tree. (J. A. LôRZiNG n. 5350, October 1Q17). 



This seems to be nearest to D. brachyotiim RCHB. F. from Java, but 

 the pseudobulbs are longer, the petals far less acutate, the lip hardly 

 acuminate with very différent keels, the side wings of the column much 

 broader. 



„Young parts more or less tinted with brown. Flowers greenish 

 brown." (LôRZiNQ).
