Hab. Andes of Peru, below Obrajillo : a pubescent form of the 

 plant. 



Both this and the nearly allied D. Mutisii, Kunth, were gathered 

 by Matthews in the province of Chachapoyas, Peru. I cannot clearly 

 distinguish the two species, except by the calyx. D. Mutisii has the 

 plumose-villous and subulate-aristiform teeth of the calyx longer than 

 the glabrous tube. In D. Onobrychis, the subulate teeth of the calyx 

 are shorter than the equally villous tube.

Hab. Obrajillo, Andes of Peru. 



Described by Hooker from more developed specimens than ours, 

 with elongated spikes, gathered by Mr. Cruckshanks in the same dis- 

 trict, " Valley of Canta." Mr. M'Lean, however, found it with spikes 

 only an inch long, like those of our plant. Mr. Matthews likewise 

 collected it at Purrochuca.
