AS degrees, with sides reflexcd at base about 1 mm. wide but not above, 

 thick and rather fleshy below, the groeve deep and half-round and 

 waterlined, about 5 mm. longer than keel. Wings about 2 mm. longer 

 than keel, linear, straight, about 1 mm. wide, with horizontal tips. 

 Keel 7-S mm. long, about 3 mm. wide, strongly incurved from near the 

 middle to erect or nearly so at the tip which is blunt and rounded and 

 about 4 mm. high. Caly.K nigrescent with appre?sed black and spread- 

 ing white hairs, with tube about 7-8 mm. long, a little inflated, some- 

 what narrowed at tip. nearly truncate at base and somewhat obliquely 

 inserted, cieft deeper above, about 3 mm. high, v/ith pubescence be- 

 comins shaggy and long and somewhat spreading, with teeth subulate, 

 arcuate, black and 3 mm. long. Pedicels very short and stout, much 

 exceeded by the triangular spieading bract.s which are 3-4 mm. long. 

 Peduncles 5-8 cm. long, slender, brown and like the petioles but a little 

 thicker. Leaves many, rosulate, 5-10 cm. long, not very narrow, with 

 petioles about as long as the rachis. Leaflets 3-6 pairs, oblong to nai- 

 rowly elliptical, 8-15 mm. long, rather thin, shortly acute at both ends 

 but sessile, not contiguous, thinly pubescent with closely appres.'-ed 

 but rather long hairs, the whole plant with a kind of lead color. The 

 crowns are mostly single and thick with innumerable old and brown 

 leaf-petioles, the stipules narrow and rarely visible. Acaulescent. 

 Roots slender, very long and erect. This very distinct species rarely 

 hybridizes and yet is a close relative of A. Newberryi but has a much 

 restricted range. It grows on sagebrush benches in the foothills un- 

 der tlie shade of the bushes, rarely in the open when it is more con- 

 densed. Common in the Oquirrh Mts. Utah and westward to Detroit 

 but not yet found in the Deep Creek Mts.. southward to Cove Fort, 

 Cedar City and Richfield, eastward from Eureka and Silver City to 

 Nephi, but not yet found in the Wasatch. Lower Temperate life 

 zone, in well drained gravel on slopes. This was referred to A. Thomp- 

 ponae ("syrticolus") by Sheldon but it has little in common with it. 

 It blooms in May. 



177 Astragalus coccincus (Parry) Brandegee Zoe 2 72 (1890). A. 

 Purshii var. coccineus Parry West Am. Sci. 7 lO (1890). A. grandiflo- 

 rus Watson not Bungc. It is unfortunate that this magificently flow- 

 ered species cannot retain the name of Watson for its flowers are 

 comparable only by the yellowish A. giganteus and the later A. fune- 

 reus. Pods a little" inflated, inclined to be sulcate below the middle at 

 both sutures and obcompresscd, the cross-section about round above, 

 with the conical tip short and about as wide as high, pods about 3 cm. 

 long and 1 cm. wide, oblong, a little wider above the middle, arched so 

 that the tip is erect or a little more incurved, the base truncate, the 

 sutures neither raised nor thickened, the walls 1 mm. thick when 

 fresh, and full of pulp, seeds filling the cavity which is hairy within 

 when fresh and with elliptical cross-section then. Flowers red, very 

 narrow and with cxserted claws (vvhich are at least as long as caly.xi 

 and narrow blades, the whole about 3 cm. long. Banner elliptic-oval, 

 about 1.5 cm. long, arched about 10 degrees in very gentle arc from 

 calyx teeth to 7 mm. beyond where the groove stops and then straight 

 to the tip, the sidc^ rc'lexed about 4 mm. wide and most below giving 

 the blade an oblon.g appearance, groove obovate and not over 7 mm. 

 long, narrowed below, the cross-section about L^-shaped. red-veined, 

 it stops about 1 cm. below the tip and then becomes a inerc line to tip 

 which is flat and 8-10 mm. wide. Wings nearly 1.5 cm. long and 2 

 mm. wide, about parallel with the upper side of keel and straight, a 

 cute on tiie lower side of the end, the ear being as long as the rest of 

 the blade' and extending 1 cm. beyond the calyx tube, a little shorter 

 than the keel. Keel Eomcwhat obliquely oblanceolate, straight, trian- 

 gular-acute, 4 mm. wide near the end and with the tip just a little 

 above the middle of the end, about as long as banner. The petals are 

 much like those of Colutea. Calyx hardly 1 cm. long, about 3 mm. 

 high, the cross-section rather triquetrous with upper side 1 mm. wide
