The type specimen of H. Schqffheri in the Gray Herbarium 

 is in an excellent state of preservation. In general habit it has 

 the appearance of a robust form of H. clypeata. Lateral sepals 

 about 1 cm. long. Upper sepal 1 cm. long, galeate, about 6 mm. 

 wide. Petals: posterior division 1 cm. long; anterior division 

 slightly longer, slender, erect. Labellum three-lobed, lateral lobes 

 subfiliform, arising about 5 mm. from the opening to the spur, 

 about 11 mm. long, middle lobe fleshy, linear-oblong, about 

 7 mm. long from the point of origin of the lateral lobes to the 

 tip. The spur resembles that of H. crassicornis.
