obconic-campanulate, lO-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 w^ith yellow resinous glands ; 

 seed 3" in diameter. — Very near the foUovs^ing species but apparently distinct.

Dale A Feemontii, Torr. Plant. Thurher., p. 316. A much-branched 

 shrub, sparingly glandular-punctate, silky puberulent ; leaves petioled, simple 

 and obovate-spatulate, or more frequently 3-foliolate 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 equaling 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" 

 long, 3" broad. — Found by Fremont on rocks in Southern Nevada. Material

Astragalus diphtsus, 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.)

 or less hoary appressed pubescent ; stems 4-15' long, decumbent or ascend-
