ORCHIDACE.E 



the raceme 2.8 dm. long, arching. Floral bracts about 3 mm. 

 long, 2 mm. wide, exceeding the pedicellate ovary. Flowers yel- 

 low. Lateral sepals 5 mm. long, oblong-lanceolate, acute. Dorsal 

 sepal similar. Petals oblong-lanceolate, acute,4 mm. long, 1.5 mm. 

 wide. Labellum five-lobed, similar to D. quinquelobum, 2.5 mm. 

 long, 4 mm. wide from tip to tip of the foremost lateral lobes. 

 Gynostemium 3 mm. high. Stelidia basal, erect, hardly equaling 

 the terminal wing, oblong, hamate, blunt. Terminal wing 1 mm. 

 long, round- triangular, entire. 



In floral structure it is almost a counterpart of D. quinque-
