muricato dispermo. — New Mexico, colL of 1851; the specimens nearly all in 

 fruit, — A species remarkable for its short and broad, nearly equilateral pods, in this 

 respect apparently much like Bentham's H. platycarpa (a species which is not be- 

 fore me) ; but that has from 4 to 6 pairs of pinnee and no glands. Our species has 

 many ascending stems from a lignescent root, slender, leafy to the top, angled, mi-

nutely pubescent or nearly glabrous, eitber glandless, or, like the petiolcs, with a 

 few scattered and sessile black glands. Leaflets minutely pubescent or glabrate, 

 3 - 5-lines long, the lower surface sprinkled with rather large, flat, and sessile black 

 glands. riowers no larger than those of H. Drummondii. Petals yellow, witli 

 rather long (reddish) slightly pubescent inappendiculate and glandlcss claws, the 

 vexillum with a few dark glands on the back. Legume 8 or 9 lines long and 4 or 

 5 broad, roundcd at the base, not in the least stipitate, the flat sides puberulent or 

 glabrate, sonietimes with. a few scattered glands like those of the leaves, the sutures
