nearly round to oval-obovate, the largest 1 cm. long, thick and flat, 
very obtuse and rounded and short-petiolulate, inthe type about 3-5 
pairs. Stems almost none, rarely 2-5 cm. long, densely congested. 
Stipules ovate to triangular, mostly overlapping, nearly 1 cm. long, 
shaggy. Whole plant hoary with fine and scarcely flattened and near- 
ly smooth hairs. Pods and flowers ascending, but pods flat on the 
ground because of declined peduncies. Bad lands from Yellowstone 
Park to the Uinta Mts. in very poor clay soil. on gentle slopes, upper 
part of the Lower Temperate life zone.‘ The var. cicadae (A. cicadae 
* Jones Cont. 4 35 (1893) is a better developed plant with leaves and 
peduncles nearly 1 dm. long, leaflets 5-7 pairs, flowers white or brill- 
jant-pink-purple with banner and wings a little longer, the banner of- 
ten 1.5 cm. long, and calyx teeth 1-4 mm. long. This abounds from 
Theodore (Duchesne) on the upper waters of the Duchesne river along 
south of the Uintas to the White river Colorado, in similar soil. All 
sorts of intergrades occur so that it seems hardly more than a form 
of the species, the calyx is often black. In its immature state with pur- 
ple flowers it is not easily separable from A. amphioxys except by the 
broader leaves and shorter flowers, the lowest leaf is ofton represen- 
ted by a single large terminal leaflet. 
As:ragalus pygmaeus var. laccoliticus (Jones Cont. 7 672 1895 as A. 
Chamaeleuce var. laccoliticus). This differs from the type in the ob- 
ovate leaflets being deltoid-acute, flowers purple, and in the ovate 
pods stronzly arcuate-tipped having the smooth outer skin of A. mu- 
siniensis. It appears like a hybrid with A. Musiniensis but A. pyg- 
maeus is not known in the Henry Mts. Cottrell’s ranch Henry Mts.

171 Astragalus Musiniensis Jones Cont 7 671 (1895). Pods oval- 
ovate to lanceolate-ovate, 2-3.5 cm. long, about 1.5 cm. wide and 1 cm. 
high, slightly arcuate to abruptly and vertically hooked with flattened 
and deltoid to triangular tip which is not produced intoa beak, round 
and sessile at base, narrowly sulcate ventrally by the suture being de- 
pressed, sometimes a little sulcate dorsally, puberulent till mature 
with short and spreading hairs, smooth and shining when old, not re- 
ticulated, single to few, cross-section oval to didymous, longitudinal 
‘section oblong to oval at right angles toa line connecting the two su- 
tures, cellular pith between the walls thick and conspicuous (about 4 
mm. thick when dry), inner wall smooth and satiny shining, pods 
wholly 1-celled, with sutures not evident nor raised externally, lying 
flat on the ground, very light when dry and blowing far away in the 
wind. Flowers rarely 5, on stout pedicels shorter than the ovate 
but subulate pointed rather smooth and hyaline bracts, dark-pink- 
purple, about 2 cm. long, just like those of A. amphioxys even to the 
horizontal and concave wings which touch at the tips. Banner oval- 
ovate, ahout 1-1.3 cm long, arcuate at the end of calyx teeth to about 45 
degrees, with sides reflexed in the middle for about 2 mms. width, 
white spot conspicuous, purple-lined and stippled. Wings narrow, 
rather abruptiy contracted above the middle, about I mm. wide, roun- 
ded, about 2 mm. longer than keel and 4 mm. shorter than banner, a 
little arched. Keel about 7-8 mm. long, gently arched from below 
the middle to erect or nearly so at tip, the tip much rounded and 3-4 
mm. high, with general outline nearly obliquely oblanceolate. Calyx 
about 1 cm. long and 3-4 mm. high, a little laterally flattened, about 
straight on both sides, iruncate at base and tip and inserted on the 
corner, nigrescent with minute black hairs, teeth triangular and hard- 
ly 1 mm. long. Peduncles scapose, about as lonz as petioles, normal- 
ly declined and hooked at the erect tip. Leaves many and congested, | 
5-7 cm. long, the crowns a mass of old and coarse and stiff petioles 
(as in A. Newberryi). Petioles with a single ovate to triangular leaf- 
let, or 3 digitate ones, or rarely with an additional pair a little below, 
leaflets normally lanceolate and short-acuminate and sessile, 15-25 
em. long. hoary with closely appressed hairs attached almost at the 
end and cross-ribbed. Crowns single to few, 1-5 cm. wide, Stipules es
