nearly round to oval-obovate, the largt'it 1 cm. long, thick and flat, 

 very obtuse and rounded and §hort-peiiolulate, in the type about 3-5 

 pairs. Stems almost none, rarely 2-5 cm. long, densely congested. 

 Stipules ovate to triangular, mostly ovci Ijtpping, nearly 1 cm. long, 

 shaggy. Whole plant hoary with fine and .scarcely flattened and near- 

 ly smooth hairs. Pods and floweirs ascending, but pods flat on the 

 ground because of declined peduncles. Bad lands from Yellowstone 

 Park to the Uinta Alts, in very' poor clay soil, on gentle slopes, upper 

 part of the Lower Temperate life zone. The var. cicadae (A. cicadae 

 Jone.s 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- 

 iant-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. AH 

 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 wdth pur- 

 ple flowers it is not easily separable from A. amphio-xys except by the 

 broader leaves and shorter flowers, the lowest leaf is ofton represen- 

 ted by a single large terminal leaflet. 



As':ra2alus pygmaeus var, 1.2ccolii:icu3 (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 strongli' arcuate-tipped having the smooth outer skin of .A. mu- 

 siniensis. It appears like a hybrid with A. .^I usiniensis but A. pyg- 

 maeus is not known in the Henry Mts. Cottreli's ranch Henry Mts.

171 Astragalus Musiniensis Jones Cont 7 671 (1895). Pod.? oval- 

 ovate to lanceolate-ovate, 2-3.5 cm. long, about 1.5 cm. wide and I cm. 

 high, Slightly arcuate to abruptly and vertically hooked with flattened 

 and deltoid to triangular lip which is not produced into a beak, round 

 and sessile at base, narrowly sulcate vcntrally 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 to a 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. amphio.xys even to the 

 horizontal and concave wings which touch at the tips. Banner oval- 

 ovate, about 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 stipple<l. Wings narrow, 

 rather abruptly 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 rounder! and 3-4 

 Sim. high, with general outline nearly obliciuely oblanceolate. Calyx 

 about 1 cm. long and 3-4 mm. high, a little laterally, flattened, aboat 

 straight on both sides, truncate 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 long as petioles, normal- 

 ly dcclinerl and hooked at the erect tip. Leaves many and congested, 

 5-7 cm, long, tlie crowns a mass of old and coarse and stiff petioles 

 (as in A. Newberryi). Petioles with a siiig'e 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. 1.5-2.5 

 cm. long, hoary with closely appressed hairs attached almost at the 

 ead and cross-ribbed. Crowns single to few, 1-5 cm. wide, Stipules
