veined, 3-4 mm, long and high, arched into about a half circle, on 
a rather long-exserted claw. Calyx oblong-campanulate, 4-7 mm. 
long, nigrescent, the triangular-subulate teeth about as long as tube 
but variable. Pedicels 2-4 mm. long with bracts ovate to lanceolate 
2-5 mm. long and hyaline. Peduncles 5-15 cm. long, rarely as long 
as leaves, stout. Leaves with variable petioles but never as long 
as rachis, 1-2 dm. long, the rachis and peduncles coarsely sulcate. 
Leaflets 6-12 pairs, round to rather broadly elliptical, shortly petio- 
lulate, veinless, rounded to notched, 2-15 mm. long. Stipules ovate 
to triangular-subulate, not connate, spreading and rather stiff, rarely 
5 mm. long. Stems tufted from a branched and woody root, as- 
cending, branched below, a few inches to 2 ft. high, the pods about 
pendent on the nearly horizontal peduncles. Growing on gravelly 
slopes and flats in rather poor soil From western Wyoming on the 
bad lands and the western base of the Wasatch through San Pete 
and Sevier Valley to Cedar City and Pioche Nevada and northwest- 
ward to the Tukenon river Washington and Spence's Bridge B. C. 
and the Snake River valley and Lewiston, Idaho, more common at 
the north. Lower Temperate life zone. 
Astragalus Beckwithii var. purpureus Jones Cont. 3 288 (1893). 
A. artemisiarum Jones. Pods filed with pulp when young and 
becoming very rigid when ripe. Flowers with purple banner and 
keel and bases of wings, white spot purple-veined. Wings obliquely 
ovate. Leaflets inclined to be diamond-shaped, not over 1.2 cm. long, 
about 1 cm. wide. 'This is the common form in eastern Nevada. 
Astragalus Beckwithii var. Weiserensis Jones Cont. 9 47 (1900). 
Pods little mottled, coriaceous, about 4 mm. high, 1 cm. wide and 
2.5 cm. Jong, arcuate to about one third circle, pungently acute, oblong- 
elliptical, ventral suture raised as a wing 1 mm. high. Flowers few, 
racemose to almost capitate, about 2-2.5 cm. long, not colored, thick. 
Banner abruptly arched at calyx tips, about 4 mm. longer than wings. 
Wings boardly linear to ellipticaloblanceolate 3-4 mm. wide, 3-4 
mm. longer than keel, almost acute. Calyx tube about 4 mm. long 
and high, with the narrowly-linear teeth as long as tube as in A. 
megacarpus. Bracts about 1 cm. long, two to three times as long 
as the pedicels. Peduncles about half as long as the leaves. Leaves 
about 2 dm. long, with 6-8 pairs of elliptical to obcordate leaflets, 
mostly 2 cm. long. Stipules very large, deltoid, 1 em. long. Stems 
rather stout a foot long, decumbent. Growing under the sagebrush 
at Weiser Idaho, on the edge of the Lower Temperate life zone. 
This has many of the characteristics of A, megacarpus as to flowers 
and general habit. 'Though there are certain marked differences in 
podsthe remarkable similarity in flowers and general habit shows that 
all the species of this group are intimately related. Watson’s No. 
271 is a mixture of material, that from the Coyote Mts. Nevada is 
this variety in all probability. 
78. Astragalus triquetrus Gray Proc. Am. Acad. 13 367 (1878). 
A. Geyeri var. triquetrus (Gray) Jones. Pods somewhat arcuate- 
oblong, deltoid-acute at tip, and obtuse but somewhat narrowed at 
base, about 6 mm. high and 3 mm. wide, deeply sulcate dorsally, and 
with suture slightly produced below the middle, with flat sides, the 
ventral suture a little concave and a mere line, the tip flat, finely 
nerved and smooth, Flowers minute, white, those of A. Geyeri. 
Peduncles axillary, very slender and much shorter than the leaves. 
Leaves 3-5 cm. long, short-petioled, many, divaricate. Leaflets about 
4 pairs, elliptical, 5-8 mm, long. Stems flexuous, 1-2 dm. long, freely 
~ branched, spreading from a slender annual root. Internodes 1-3 em. 
. long. Pubescence ashy. Sandy deserts of southeastern Nevada.
