prominent and sharp edged externally, pod arched into one-third ~

equaling tip of calyx teeth; pods shorter, slightly arched, both 
sutures prominent, not at all sulcate or with only a trace of it. 
My own specimens gathered at Carson City, Nev., May 23, 
1882, are exactly the type of A. Gibbsiz. Those collected also by 
me at Empire City, Nev., June 20, 1882, and distributed as No. 
3829 have the flowers of A. Gzddsz7 but the calyx a little narrower: 
pedicels as long or two lines long; leaflets six to ten pairs, like 
those of Mr. Lemmon’s specimens, short- woolly, and whole plant 
canescent throughout; pods very short-pubescent, not at all 
sulcate, cross-section about circular, pod an inch long, bent into 
fully or more than a semi-circle; stipe equaling or twice as long 
as the calyx; pods oblong-linear, shortly and equally acuminate 
at each end, stems branched above, a foot high. Other speci- 
mens gathered at the same place have pods the same width as 
the above but only one-half an inch long, very sharply acuminate; 
stipe shorter than the calyx; pod snebHy arched, otherwise as 
above. 
Astragalus recurvus Greene. his is A. obscurus Watson. I 
have specimens of 4. odscurus from Nevada collected by myself 
with recurved pods, and also specimens from Northern Arizona 
collected by me near Flagstaff in 1891 with the pods curved fully 
as much as the type and with crimped edges. 
Astragalus adsurgens Pall. *This species is in great need of a 
new description for the lobes of the calyx are often as long as 
the tube, the leaflets vary from linear lanceolate and one and one- 
half inches long to oblong-elliptical and obtuse or acute. ‘The 
pods are one-celled, sulcate dorsally from one-fourth to one- 
third their width and dorsal septum produced a much more into 
the pod, but never two-celled; the flowers are purple or white. 
My specimens were named by Gray. 
Astragalus cireumdatus Greene. Scytocarpi, and nearest to 4. 
Chameleuce, but widely different from it. In uniqueness it ranks
