142 MINNESOTA BOTANICAL STUDIES. 



nearly terete; lea/lets 5 to 8 mm. in length, in three to five 

 pairs, elliptical to lanceolate, acute, pubescent both sides; 

 sUpules ovate-lanceolate, long-acuminate, usually closely im- 

 bricated; pedundes 1.5 to 2 cm. in length, two-flowered; floivers 

 2.5 to 2.75 cm. in length, narrow, each subtended by a black- 

 bordered bract; calyx 12 to 15 mm. in length, tubular-cylindri- 

 cal, oblique at base, spreading-pubescent, striate, the lanceolate 

 teeth nigrescent- margined and from one-fifth to one-fourth the 

 length of the tube; corolla purplish, tinged with green; legume 

 10 to 12 mm. in length, ovate-arcuate, acute or shortly acumin 

 ate pointed, incurved, coriaceous, sessile, white pubescent, 

 unilocular, but the dorsal suture slightly impressed, few seeded. 

 Collected on the Rattlesnake mountain, Yakima county, 

 Washington, June, 1884, also near Walula, Walla Walla county, 

 Washington, April, 1891, by Mr. W. N. Suksdorf. The first 

 collection furnished the stemless and carpological characters 

 of the description and the second the floral and short-stemmed 

 characters. The species is near to Astragalus candelarius 

 Sheld. , but is very dwarf as compared with it and the pubes- 

 cence is white-woolly throughout, even to the legumes. 



Astragalus candelarius n. sp. 



Perennial, erect spreading, woolly -pubescent with appressed 

 white hairs; siems 10 to 13 cm in length, diffusely branching, 

 striate, with somewhat spreading pubescence; leaves 6 to 8 

 cm. in length, the rachis sulcate; leaflets 10 to 14 mm. in length, 

 in four to five pairs, absent from the lower half of the rachis, 

 broadly obovate, obtuse or retuse; s/«puZes narrowly triangular- 

 acuminate, erect, persistent slightly sheathing; peduncles 

 equalling the leaves, loosely four to six flowered; -y^oioers 2.5 

 to 3 cm. in length, slender, erect; calyx narrowly cylindrical, 

 becoming expanded and at length broken by the enlarging 

 legume, persistent, thin chartaceous, lavender-purple, sparcely 

 soft-pubescent, the triangular-acuminate teeth one-sixth the 

 length of the tube; corolla ochroleucous tipped with purple — in 

 dried specimens; legume 2 to 3 cm. in length, coriaceous, 

 pubescent with yellowish hairs, sessile, expanding the calyx, 

 oblong or ovate, not arcuate, completely unilocular, not 

 obcompressed, and neither suture intruded, cavity smooth, 

 lined with a brownish membrane, few to many seeded. 

 Collected on open sand and among rocks near Candelaria, 

 Esmeralda county, Nevada, April and May, 1888, by W. H.
