This species differs from I), virgatus in its shrubby habit, lower leaves, larger 

 and more numerous pods, etc. The marking on the side of the seed referred 

 to hy Mr. Brandege(! in his notes of this species seems to be a generic character, 

 and as it also varies in shape and size in different species it may be of some use iu 

 identification. In D. virgatHH, although the seed is not half as large as in the 

 above sp<'cies, the mjirkiug is nuich larger.
