proper stems rather short; leaves 3-4 on the stem, about 

 7' long, about 6-8 pairs of oval, obtuse, almost contiguous 

 leaflets, 8" long, 3" wide, glabrous above, hoary below, as 

 well as the stems; peduncles and petioles with white, 

 short, narrow, appressed hairs, fixed by the base. This 

 is a perennial, growing in gravelly soil among the junipers, 

 on the mesa above the Grand Wash. 



This seems to differ well from A. iir sinus, and in case 

 it should prove distinct, may bear the name A. ensiforniis. 



ASTRAGALIS NeWBERRYI Var. CASTOREUS. 



No. 5006. April 4, 1894, Copper Mine, 18 miles west 

 of St. George, Utah, in gravel, 5000° alt. 



Leaflets 2-3 pairs; calyx usually black-hairy, 8" long, 

 and teeth i^" long; corolla dark purple like the type, 

 5" long; pod 15^' long, arched into three-fourths of a 

 circle and long-acuminate from the base, completely ob- 

 compressed at the base and not at all so at the apex, but 

 rather compressed, shortly shaggy all over, with rather 

 sparse hairs. In other respects this appears like the type, 

 but the pod is very different. Because of the variability 

 of the pod in this species I cannot consider this as more 

 than a good variety. 



This may prove to be too near to A. ciharius Sheldon. 



Astragalus remulcus. Rusby,No. 576, Bangharte's 

 Ranch, Arizona, May, 1883. Probably also G. R. Vasey, 

 Kingnian, Arizona, June, 1881. With the habit of A. 

 Shortianiis, and somewhat related to it. Perennial, rather 

 stout, stems spreading over the ground, with erect or 

 ascending peduncles; proper stems 6' long, but may be 

 much longer; puberulent; stipules triangular, green, 

 adnate, not connate, reflexed, 2" long; leaves 6' or less 

 long; the petiole one-third the rachis, and stout and sul- 

 cate; leaflets glabrous above, strigose below, with fine
