Davis (Wheeler's) Peak, and probably north through the desert, 

 Growing in strongly salty places in clay, along with Sarcobatas. 

 Blooming in May, fruiting in June. 



98. Astrac;alus Rafaelensis N. Sp. Pods oblong, nearly round, 

 about 1.5 cm. long and .5 8 mm. wide, abruptly rounded at both ends, 

 with very short and deltoid apiculate beak, the ventral suture con- 

 spicuously arched and the dorsal nearly straight, reflexed on stout 

 pedicels, which are 3-5 mm. long and which fully equal the ovate 

 bracts, in long racemes on slender peduncles, splitting thro^igh both 

 sutures to the base till the valves fall away. Flowers reflexed early, 

 light-purple or white and tinged with pink, scattered. Banner nar- 

 rowly ovate, about 2.5 cm. long, wtih sides inclined to be reflexed 

 which makes it seem linear-oblong, barely notched, the reflexed 

 area about 3 mm. wide at point 3 mm. back of keel but not at all at 

 tip. "^Tiite spot deltoid, barely colored except for the light-purple 

 veins, 3-5 mm. long. Groove a half circle at keel tip and 1 mm. deep 

 and shallowing quickly, the banner a little hooded at tip, and erect 

 at point 4 mm. beyond the calyx tips. Wings nearly straight, ob- 

 long oblanceolate, base 2 mm. wide and 3 mm. wide above, pink at 

 base and white beyond keel and 6 mm. longer, acutish but rounding 

 toward tip. Keel straight, arched to 100 degrees in a sharp arc at 

 the end, deep purple and barely acute. Calyx pink, about as long as 

 wide, barely laterally flattened, straight, smooth, scarcely narrowed 

 at tip and cleft but little deeper there, nerved. Teeth triangular, 2 mm • 

 leg. Tube 4 mm. long and 3 mm. wide, hyaline, red. Pedicel insert'i'u 

 about one third the way from the lower corner, about 2 mm. long. 

 Stipules connate nearly to the tip below, nearly distinct above, re- 

 flexed, nearly hyaline throughout. Leaves more filiform than usual 

 channeled, of 1-2 pairs of delicate leaflets which are rarely over 1.5 cm. 

 long. The plants grow in very dense tufts with very many stems in 

 a b'mch from a woody root, about 2 feet hi2;h. str;'ight, in san(iv 

 places on sandstone ridges, there being no particular evidence rf 

 alk'H. though soil is alkaline near Cedar Mt. Utah which is near 

 Woodside, 4 500 feet alt. in the Lower Temperate life zone. M:iv 

 19, ]l^t'). This is an interesting addition to this group and is evi- 

 dently closely allied to A. Toanus. 



99. Astragalus Gray! Parry Am. Nat. 8 212 (1874). Pods erect 

 to ascending, narrowly-oblong, taper-pointed, not splitting the calyx, 

 about 3 mm. wide, little more than coriaceous, half-exserted from 

 calyx, about like those of A. Toanus, its thicker forms but not com- 

 pv. sse'L tie dorsal suture nearly straight and tip the nrolongntion of 

 it. ventral decidedly arched and pod appearing inverted, not fleshy 

 noticeably. Flowers rather spicate, many, on subterminal peduncles 

 longer than t-he leaves. Calyx teeth inclined to be subulate. Leaves 

 about 8-10 c!u. long. Leaflets ?.-4 cm. long, not folded, apiculate, 

 about 4-5 mm. wide, a little wider above, jointed to the rachis, 2-3 

 pairs. Tnternodes about 3 cm. long. Green River Desert W^yoming, 

 sandy hills. 



100. Astragalus pectinatus Douglas in Hook. Fl. Bor. Am. 1 141-2 

 t 54 (1830). Tragacantha Kuntze. Phaca Hook. Ctenoiihyllura Ryd- 

 berg. Pods closely reflexed, oblong-oval to elliptical, rarely nearly 

 globose, obtuse but very strongly apiculate-beaked, rarey triangular- 

 acute and oblong, conspicuously fleshy and with sutures raised at least 

 1 mm. in the dry pods, splitti'^g the calyx .generally rugose, 1-1.5 cm. 

 long, 9-12 mm. wide, about 4 mm. thick, normally 9 by 7 mm. long and 

 wide, when fresh the i)ods are traversely oval in cross section and a 

 little sulcate ventrally, the dorsal suture a little raised. Flowers nor- 

 mally rich cream-colored, white below, about 1.3-2 cm. long. Banner 

 arched from 45 to 90°, sides reflexed most above and making it seem 

 taper-pointed, tip very thin and erose, base thick and fleshy. Calyx 

 teeth inclined to deltoid. Bracts stiff, green or scarious, linear-lanceolate
