Brazil : without locality, Ferreira, 745. 



Nothing more definite is known of the native country of this species, 

 which has been confounded with //. discolor, JMuell. Arg. in the 

 Herbarium, It strongly resembles this species in foliage, but the 

 flowers, especially the males, are much larger, and the perianth quite 

 different in shape. — W. Botting Hemsley.
