oblong-ovate, not acuminate, nearly smooth, rarely visible, On barren 
clay slopes from Price to Ferron Utah and vicinity, Lower Temper- 
ate life zone. 
A common from with shaggy young and sparsely. shaggy old pods 
and 3-5 leaflets from Thompson's Spring and the San Rafael Swell in 
Utah is the var. Newberryoides. The true A. Newberryidoes not oc- 
cur in this region. 
This species though quite distinct simulates A. Newberryi in many 
respects. The flowers are the same, the ieaf habit the same though 
the latter runs into rather many leaflets in the variety, the condensed 
crowns the same. The leaflets of A. Newberryi though normally 
nearly round are often inclined to be tapering at tip. The pods are 
very different when mature. A. Newberryi belongs to the Great Ba- 
sin region though crossing the Colorado drainage at the south, whie 
A. Musiniensis grows oniy on the northern part of the Navajo Bas 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.cymboides. [tis 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, - 
eross-section when dry oblong by the inner walls being much obcom- 
pressed, not sulcate, pods when old appearing nearly 1.5 cm. wide and 
bordered by a line (the edge 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 bnt 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 
reflexéd near the base to 1 mm.’s width and so making the blade seem 
fiddle-shaped, deeply notched and with groove nearly V-shaped and 2 
mm.deep and 1 mm. wide below, then becoming 2 mm. wide and U- 
shaped above and vanishing at tip. Wings Re 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 
 appressed pubescent, teeth triangular, about 1 mm. long. Peduncles 
from spreading to flat on the ground, rarely 5 cm. long in flower or 7 
mni. long in fruit, normally shorter than the leaves, rather stout, — 
scapose. Leaves 3-8 cm. long, with coarse and persistent petioles 
. mostly twice as long as the rachis. Leaflets 3-5 pairs, normally oval- .
