purple spotted, young pod pulpy and corrugated, mature pod 

 with membranous outer coat very coarsely reticulated transversely 

 and 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 pod of 

 A. Prei(ssii it seems better to describe them as varieties until 

 the real limits of that species are known. 



Astragalus Preussii 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 an inch 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 aline 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 Preussii 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; 

 pod 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; pcd thick-chart£ceous, but not
