Astragalus megacarpus var. caulescens. 



No. S639f. July 17, 1894, Loa Pass, Utah, 8000° alt., 

 in gravel under sagebrush. 



This has large leaves, 6' long, stems a foot high, with 

 large, green triangular stipules 2-3" long and stipe as 

 long as the calyx. 



The variety Parryi Gray has elliptical leaflets and pods 

 i;^' long on a stipe %" long. What appears to be nearly 

 the same, from Peach Springs, Arizona, by Lemmon, has 

 a stipe as long as the calyx, and teeth, and stems from 4— 

 6' long; the pod is as described above, but elliptical-oval. 

 It is quite probable that both varieties will prove to be 

 only forms not deserving varietal rank.

 Utah, 4000° alt., in red sand.
