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

Astragalus iodanthus Watson, Hot. King's Exp. 5, 70. 

 This plant, which Watson confounded with a much better 

 marked species A. arietinus, 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, 1-1%' long, less than 1" 

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

 nosus. Specimens in the National Herbarium besides the 

 tvpe are Sierras, California, Lemraon ; Virginia City, 

 Nevada, Curran, July, 1884. 



Astragalus lotijlorus var. brachypis 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 type form are found on 

 the same plant, the length of the peduncle being only 

 accidental, this will reduce the variety therefore. 



Astragalus Leibergi. No. 354, Sandberg and Lei- 

 berg, Egbert Spring, Douglas County, Washington, alt. 

 3500 , July 1, 1893. Type in National Herbarium.
