U12 



oblong-ovatc, not acuminate, nearly smootli, rarely visible. On barren 

 clay slopes from Price to Ferron Utah and vicinity, Lower Temper- 

 ate life zone. 



.'\ common from witli shaggy young and sparsely shaggy old pods 

 andv3-5 leaflets from Thomi'son's Spring and the San Rafael Swell in 

 Utah is the var, Newberryoides. The true .\. Xewberryi does not oc- 

 cur in this region. 



This species though quite distinct simulates A. Newberryi in many 

 respects. The flowers are the same, the leaf habit the same though 

 the latter runs into rather many leaflets in the variety, the condensed 

 crowns the same. The leaflets of A. iS'ewberryi though normally 

 nearly round are often inclined to be tapering at tip. The pods aie 

 very different when mature. -A.. Xewberryi belongs to the Great Ba- 

 sin region though crossing the Colorado drainage at the south, whi e 

 A. Musiniensis grows only on the northern part of the Navajo Ba^ n. 

 It has the appearance of a hybrid between A. pygmaeus and some 

 other species, but there is no such other species. Its only associate is 

 A. cymboifles. It is common and holds its characters. The tap root 

 is many feet long. 



172 Astragalus cymboides Jones Cont. 7 650 (1895). Pods light- 

 colored, acute at both ends, about 8 mm. wide and high, sharp-edged at 

 both sutures, and with sides rounded, the pulp nearly 2 mm. thick and 

 quickly shriveling when picked, the coat becoming horizontally lined 

 along the middle and with fine but rather indistinct cross lines and un- 

 evenly pitted, ashy, with tip flat and triangular-acute and straight, 

 cross-section when dry oblong by the inner walls being much obcom- 

 pressed, not sulcate, pods when old appearing nearly l.S cm. wide and 

 bordered by a line (the e>lge of the suture), hardly 3 mm. thick in the 

 middle and keeled below (the keel the dorsal suture), trisulcate above 

 by sharp grooves with the central one at the ventral suture and the 

 lateral pair of grooves where the outer wall (now become a wing) 

 joins the dody, the space between the central and the lateral grooves 

 is very convex so that the cross-section is about like the figure "3" but 

 with the upper arc the same as the lower. Seeds many and filling the 

 hairy cavity which splits along the ventral suture but does not open 

 except a little at the end. The dry pods are very light and blow about 

 easily. Flowers about 1.5 cm. long, dull-purplish to dirty-white, with 

 the tips inclined to be purplish but the banner nearly always white, 

 capitate, rarely 12. nearly sessile and with the ovate bracts much lon- 

 ger than the pedicels. Banner water-lined, oblong-oval, about 8 mm. 

 long, arcuate abruptly beyond the calyx teeth to 45 degrees, the sides 

 refiexed near the ba-e to 1 mm.'s width and so making the blade seem 

 fiddle-shaped, deepl} notched and with groove nearly V-shaped and 2 

 mm. deep and 1 mm. wide below, then becoming 2 mm. wide and IJ- 

 shaped above and vanishing at tip. Wings linear-oblong, a little 

 arcuate, notched below the tip, blunt, close-pressed and convex to keel 

 below and then spreading and horizontal above, pink-purple and 

 striped, 1 mm. wide. Keel sharply arched in the middle to erect and 

 with erect part about 3 mm, long and as long as the base which is 

 straight and with rounded tip, about 1 mm. shorter than the wings 

 which are 2-4 mm. shorter than banner. Calyx about 7 mm. long and 

 2 mm. high, cylindrical, obliquely-triangular at base and inserted in 

 line with it, the upper side a little arched, laterally flattened, cleft 

 deeper above and oblique at tip, inclined to be nigrescent and densely 

 oppressed pubescent, teeth triangular, about 1 mm. long. Peduncles 

 from spreading to flat on the ground, rarely 5 cm. long in flower or 7 

 mm. long in fruit, normally shorter than the leaves, rather stout, 

 scapose. Leaves 3-S cm. long, with coarse and persistent petiole^ 

 mostly twice as long as the rachis. Leaflets 3-5 pairs, normally ovnl- 

 obovate, sometimes elliptical to oval, acutish, nearly sessile and thick 

 5-10 mm. long. Stipules densely imbricatec, triangular-ovate, 5-8 mm
