Dendrochilum palawanense Ames Orchidaceae II; 103, fig. 



Mr. Elmer's specimens from the island of Palawan agree

 slightly less than 15 cm. high from the base of the pseudobulbs 

 to the tip of the raceme. The leaves, including the petiole, range 

 between 7 and 11 cm. in length and are linear-lanceolate, attenu-
