The present plant is, in all respects, like D. viUosa DC. But, 

 in this new species, the seed is always one in each pod and the 

 standard has distinct spurs on both sides of the lamina. In 

 these respects, I think the plant is specifically separable from 

 D. villosa DC. The leaves of the specimen, upon which the above 

 description is based, are of a thinly hairy form. Here is another 

 form with villose leaves which are much smaller than the leaves 

 of the other form. The villose form seems to be a young stage 

 of the other.
