most the same as in A. simplicifolius, the banner oval and arched to 
erect, the bulge behind less evident, white spot the same, sides little 
reflexed. Calyx campanulate, about 1 mm. long, the triangular teeth 
hardly as long. Peduncles shorter than the leaves, filiform, rarely 5 
cm long. Leaves strict, not over 7 em. long, with rigid. ascending Jeaf- 
lets and short petioles. Leaflets 2-5 mm. long, thick, 4-8 pairs. grooved, 
sharp, sessile, the terminal one mostly not jointed to the green rachis, 
and like it. Petioles persistent after the leaflets fall and rigid. Pedi- 
cels 1-3 mm. long. Bracts small. Stipules conspicuously connate 
throughout, hyaline. Stems an inch or so high, much branched, many 
from the crown of the thick and erect root, with’the stipules over- 
pping to the tip of the stem. Growing in clay soil.on bare ridges of 
the bad lands of western Wyoming north of the Uintas. Middle

Phaca Rydberg. Pods racemose, elliptical to obovate, nearly straicht, 
not sulcate, translucent and very thin and papery, with oily drops 
within, red-nerved and stippled above, horizontal to pendulous, 3-4: em. 
long, about 2-2.5 cm. wide, compressed at base, splitting with age from 
tip to base and through the pedicel along the dorsal suture, also along 
‘he ventral suture at tip and base, but not through the seed bear- 
ing portion, tip very shortly triangular or deltoid and oblique, 1-4 mm. 
long, cross section half-oval, shallow and very broadly sulcate ventral 
ly. Stipe not longer that calyx and not jointed to it and so pod is per- 
sistent even through the winter on dead stems. Flowers coarse, about 
the same as A. stenophyllus, nearly horizontal, loosely spicate, rather 
few. 1-1.5 em. long, white turning to cream-colored with age. Banner 
fiddle-shaped by being much contracted about one third the way from 
the base, oval, 1 cm, long, arched to 90 degrees 2-4 mm. beyond the 
calyx teeth, erect part about 7 mm. long, a little hooded at tip, water- 
Uned. with fleshy claw, with sides reflexed to 2 mm. wide in the 
middle only, with groove very deep and narrowed below and flattening 
out above. Wings arched from little to 30 degrees, obliquely oblong-lan- 
eevlate, 1-3 mm. longer than keel and 2 mm. shorter than banner, 
^bcut 4 mm. wide below the keel t» and tapering down above concave 
- to keel, flaring beyond. Keel a little arched, about 4 min long (blade), 
abruptly rounded to nearly 90 degrees, yellow, with tip acute and 
about 3 mm. high. Calyx tube a little oblique at base and with pedi- 
cel inserted below the middle of the end. truncate, scareely at all 
compressed, white, straight, 3 mm. long, broadly campanulate, with 
mouth oblioue, with teeth rudimentary and deltoid, one half mm. long. 
Bracts minute and hyaline. Pedicels stout, short, some of them re- 
flexed. Peduncles subterminai. stout, long, green, sulcate, a foot or 
less long. Leaves not over 1 dm long, few, spreading, lax, nearly ses- 
sile,, with green and rush-like rachis. Leaflets deciduous, linear to fili- 
form, minute to 2.5 em. long, distant, petiolulate, the terminal one the 
Simple rachis or slightly enlarged rachis or a leaflet barely jointed to 
. it, 6-8 pairs. Stipules small, not connate except at very base. Stems 
erect, sulcate, 1-2 feet long, rather slender, flexuous, whole plant ap- 
pearing smooth but really minutely pubescent. Grows in dense tufts 
on dry rocks on south slopes in Snake river canon at and below Hunt- 
ington Oregon. Lower Temperate life zone. Plants with the habit of 
A. stenophyllus, and stems much as in A. junceus. A Aud s
