obconic-campanulate, 10-ribbed, the teeth triangular, acuminate, unequal, 
about as long as the tube ; petals deep-purple, 4-5" long, nearly as in the 
last ; ovules collateral ; pod 4-6" long, covered with yellow resinous glands ; 
seed 3" in diameter. — ^Very near the following species but apparently distinct. 
Collected by J. E. Johnson near St. George on the Virgin River, Utah, and 
also in the same locality by Dr. Palmer, 1870. 
Dalea Fremontii, Torr. . Plant. Thurher.^ 316. A much-branched 
shrub, sparingly glandular-punctate, silky puberulent ; leaves petioled, simple 
and obovate-spatulate, or more frequently 3-foHolate with obovate leaflets, 
3" long, . shorter than the petiole; flowers sessile upon the subspinescent 
branchlets, loosely spiked, spreading, bracteate with a leaf or usually with a 
small subulate bractlet, the rachis with a few minute bristles; calyx-teeth 
, very acute, the upper triangular, the lower subulate, about equahng the cam- 
panulate scarcely ribbed tube ; corolla reddish-purple, 4-5" long, the obcor- 
date banner and wings equaling the keel ; ovules not collateral ; pod 4-6"

Astragalus diphysus, Gray. Revis. Astrag., Proc. Amer. Acad. 6. 193. 
Nearly glabrous; stems 1-2° long, numerous, decumbent or ascending; 
stipules triangular, acuminate, scarious, adnate to the petiole ; leaflets 6-11 
pairs, obovate or oblong, usually obtuse or retuse ; peduncles equaling the 
leaves ; racemes short, rather densely flowered ; calyx-tube long-campanu- 
late, twice longer than the subulate teeth ; corolla 6" in length, blue or 
purple, occasionally white ; legume 1' long, ovate, membranous, inflated, 
2- celled, with a perfect septum, curved-acuminate, many-seeded, sessile ; fre- 
quently mottled. — New Mexico, Northern Arizona, and Utah. Toyabe and 
East Humboldt Mountains, Nevada; 6-8,000 feet altitude; July. This 
species may possibly be but a luxuriant, glabrous form of the next, into which 
it seems to pass. (253.) 
Astragalus lentiginosus Dougl. Gray^s Revis., I c, p. 194. More 
or less hoary appressed pubescent ; stems 4-15' long, decumbent or ascend- 
ing ; stipules small, acuminate ; leaflets 6-11 pairs, obovate, obtuse or retuse ; 
racemes short or elongated, rather densely or loosely flowered ; calyx-tube
