bent at each end; ventral suture a little concave and 

 thin, a trifle intruded, not at all sulcate ; dorsal thicker, 

 both sutures raised externally, dorsal suture intruded at 

 least half way into the pod, except at the tip, where it is 

 not at all intruded; walls cartilaginous, wrinkled both 

 ways externally, pod sessile, but a trifle narrowed at the 

 insertion; pedicels stout, 2" long, ascending, and pods 

 erect on pedicel. Very close to A. nudus Watson and 

 A. -pachyfiis Greene, differing from the former in the 

 nearly 2-celled and smaller pod, from the latter in the 

 short, sessile, round pod and few leaflets. Fish Lake 

 valley, Nevada. Shockley, July 20, 1886. 



Astragalus pruniformis. This belongs to the A. 

 f achy-pus group. Stems slender, ascending from a de- 

 cumbent base, i-i^° high, very coarsely sulcate, nodes 

 ^-■2^2' apart; leaves 3-4' long; leaflets 6" long, oblong, 

 with a cuneate base, emarginate, 2" wide, thin, pilose 

 with fine, loosely appressed hairs, fixed by an enlarged 

 base; peduncle stout, G long, floriferous on the upper 

 third; stipules subulate, green, i" long, reflexed in fruit; 

 calyx campanulate, tube- about i>^" long, teeth subulate, 

 and as long; pedicels stout, Y^' - long, equaling the tri- 

 angular-subulate bracts; stipe slender, 3" long, ascending; 

 pod in the fleshy state probably round in cross-section, 

 and almost exact oval, 4" long by 3" wide, with much ex- 

 ternal pulp, when dry pods are lenticular in cross-section, 

 parallel (transversely) ridged and reticulated, ventral 

 suture ^" thick throughout, dorsal also raised but 

 thin, pod strongly apiculate, the point being a little above 

 the middle of the end, 2-celled to the very apex, with the 

 septum double and the parts separate; flowers not seen.
