ope spotted, young pod pulpy and corrugated, mature pod 
membranous outer coat very coarsely reticulated transversely 
i suggesting the wing of a cicada, inner skin stiffer, both 
sutures much thickened within and pulpy but not much 
intruded, pod occasionally slightly sulcate ventrally, very acute. 
Grand Junction, Colo., May, 1892. Collected by Miss Alice 
Eastwood. 
The following forms, except the first, would readily pass for 
new species, but in view of the great variability in the po 
A. Preussti it seems better to describe them as varieties until 
the real limits of that species are known. 
Astragalus Preussiti Gray, Proc. A. A. vi, 222. See also 
Vol. xiii, 369, and Bot. King’s Exp. Rev. Astragalus, Watson. 
The specimens collected by Miss Eastwood at Moab, Utah, 
May, 1892, approach the type very closely. Glabrous throughout 
except calyx speckled and teeth black with flat, short-twisted 
hairs fixed by the base, plant a foot high; leaflets oval to 
narrowly elliptical. Peduncles equaling the leaves, stout, five to 
ten-flowered; flowers spreading and in fruit ascending, purple, 
three-fourths of aninch long; pedicels a line long and twice shorter 
than the ovate, hyaline, acuminate bract; calyx five lines long, 
two lines wide at base, and one and one-half wide at throat, cleft 
a little deeper on the upper side, teeth subulate, a line long; keel 
straight, to moderately incurved at blunt apex and scarcely 
shorter than the wings, banner elongated, purple veined, 
ascending; pod with evident sutures, abruptly contracted at each 
end, and with subulate point at apex a line long, this broad based 
beak is very characteristic, the stipe is about two lines long, and 
the pod is oblong elliptical. Otherwise agreeing with the type 
exactly. Collected by Miss Alice Eastwood at Moab, Utah, 
May, 1892. 
Astragalus Preussit Gray var. LATUS, n. var. Leaves obovate- 
cuneate to nearly linear; peduncles longer than the leaves; calyx 
cylindrical; banner shorter and wings longer than in the above; 
nearly round, but ventral suture nearly straight, three- 
fourths of an inch long, apex subulate three lines long and 
prow-like, stipe two lines long; pod thick-chartaceous, but not
