 what prominent beneath; veins inconspicuous superficially in

 shorter and broader than the upper one, very slightly adnate to 

 the base of the column, 15 mm. long, 10 mm. wide. Petals free, 

 spathulate, attenuated below, nearly equal in length to the 

 upper sepal. Labellum sessile, continued, adnate to the lower- 

 half sides of the column, shortly calcarate behind at the base, 

 nearly horizontal, scarcely incurved, 15 mm. in whole length
