CONTRIBUTIONS TO WESTERN BOTANY. ,66^ 



Astragalus racemosus var. longisetus. This has- 

 very long hyaline, setaceous bracts as long as the calyx 

 tube; often robust and with leaflets 3" wide by 8" long, 

 ■elliptical, and large reflexed stipules. The specimens 

 which form the types of this variety are in the National 

 Herbarium. Wolf, No. 216, Apex, Colorado, June ; Fort 

 Collins, Colorado, on prairies; Sheldon, Pueblo, Colo- 

 rado; Bodin and Eastwood, Denver, Colorado; Idaho, 

 Hayden's Survey; Moose Jaw Creek, N. W. Q., on open 

 prairies, Macoun. 



AsU'agalus iodanthus Watson, Bot. King's Exp. 5, 70. 

 This plant, which Watson confounded with a much better 

 marked species A. arietimis, so far as the type is con- 

 cerned belongs to western Nevada and adjacent Califor- 

 nia. It has slender stems; nearly glabrous throughout; 

 flowers white, narrow, smaller; wings and banner usually 

 equal; calyx lobes filiform-subulate nearly equaling the 

 short tube; pods lanceolate-acuminate, completely ob- 

 compressed till the opposite sides touch throughout ex- 

 cept at the tip ; walls thin, merely coriaceous, pod mottled, 

 minutely puberulent, 3-4" wide, i-i)^' long, less than i" 

 thick. In some of its forms this approaches A. lentigi- 

 nosiis. Specimens in the National Herbarium besides the 

 type are Sierras, California, Lemmon; Virginia City, 

 Nevada, Curran, July, 1884. 



.Astragalus lotijior us Y2iX . h7'achyfus Gray. This plant 

 seems to be a good species, but those most competent to 

 pass an opinion on it, the field collectors of the plains, 

 say that both this form and the t3^pe form are found on 

 the same plant, the length of the peduncle being only 

 accidental, this will reduce the variety therefore.

 3500", July I, 1893. T3^pe in National Herbarium.
