 1873:25. F.M. 1875:168. Hardy. The color of the 

 fls. varies considerably in this species. In some the 

 inner segms. are nearly white, while in others they are 

 nearly as dark as the outer. The species is chiefly dis- 

 tinguished by the curious spoon-shaped concave outer 

 segms. and the depressed style-branches which give the 

 fls. an appearance different from the other members of 

 this group.
