close to calyx, jointed to a minute stipe at base, ascending or reflexed, 
both sutures evident and nearly alike, the ventral intruded 1 mm. deep 
or less; seed talks as long as the obliquely reniform seeds which are 
nearly 2 mm. long and brown. Flowers racemose, 10-15. Banner 1-2 
mm. longer than keel, nearly round, notched, with sides reflexed below, 
arched in an abrupt curve from calyx tips to nearly erect. Wings nearly 
‘linear, arched and exposing keel, a little longer than keel, oblique. 
Keel ascending, about reaching to calyx tips, abruptly bent at tip to 
90 degrees and acutish, Calyx tube faintly 5-nerved, ashy campanu- 
late, not gibbous, 3 mm. long and as long as the subulate teeth or a 
little longer. Bracts ovate, acute, Pedicels erect in flower and reflexed 
variably to horizontal or more in fruit, 4 mm. long, usually twice 
the bracts, stout. Peduncles angled, stout in fruit, erect, including 
floral rachis 12-15 cm. long and floriferous on the upper third. Leaves 
5-10 em. long, nearly sessile.. Leaflets 6-9 pairs, linear-oblong, barely 
obtuse at tip and base or notched above, all on the upper side of the 
rachis, about 1 cm apart. Internodes about 2-3 cm. long, the lowest 
ones 5-10 cm. long. Stems rather coarse, 2 feet high, tufted, decum- 
` bent, angled,. Plants very minutely puberulent, the young pods, pedi- 
cels and peduncles hoary at first. From the Organ Mts. New Mexico 
to the Colorado through the Mogollons. Lower Temperate life zone. 
‘Growing on gravelly and dry benches or along dry watercourses. This 
is hard to separate from robust forms of A. triflorus except by the 
larger purple flowers and evidently perennial roots from a rather 
woody base. Plants distributed by E. O. Wooton from Mesilla Val- 
ley April 20 1905 as A. Wootoni Sheldon are this species, also No. 34 
Metcalf from near Silver City New Mexico distributed as A. playanus. 
It is quite possible that Sheldon’s type was mixed with A. subcinereus. 
64. Astragalus Wetherilli Jones Cont. Cont 4. 34 (1893). Phaca 
Rydberg. Pods ascending, shortly acuminate, half-oval-ovate, about 
_ 2-2.5 cm. long and 1 cm. wide and high, very slightly flattened laterally 
and cross section’nearly round but flat along the ventral suture, not 
sulcate, chartaceous, rounded at base and jointed to the tip of a 
slender stipe nearly as long as calyx, sometimes reddish but not mot- 
tled. Flowers about 1 em. long, narrow, white or only purple tinged, al- 
most in heads, ascending. Banner about 6 mm. long, oblong, abruptly 
arched remote from calyx tips to 45 degrees, 2 mm. longer than wings, 
with sides reflexed about 1 mm. wide. Wings nearly linear, arched to 
nearly 45 degrees, obtuse, a little longer than keel. Keel with straight 
and narrow base about 1 mm. wide, the tip sharply rounded to a 
holf circle and very obtuse, 2 mm. high, purple at tip. Calyx narrowly 
campanulate, the tube about 3 mm. long, acute at base and attached 
en lower corner, the sııbulate teeth nearly as long as tube, nigrescent, 
Pedicels stout, nigrescent, 2-3 mm. long, about as long as the triangular 
bracts. Peduncles slender, 2-4 cm, long. erect. fruiting rachis 1-2 
em. long and rarely with more than 3 pods and half a dozen flowers. 
Leaves 4-5 cm. long, slender and thin, all petioled, the lower petioles 
more than half the whole, the upper nearlv half.: Lower leaflets nearly 
round and shortly-cuneate at the long-petiolulate base, upper leaflets 
broadly elliptical, about 1 em. long, flat and thin, rounded, 4-5 pairs 
or the upper 6-8 pairs, almost smooth. Stems slender, in dense tufts 
et much branched woody base. ascending, flexuous, about 2 ft. high. 
Stipules small, not connate. Peduncles in most of the axils. Along 
the Grand River near Grand Junction Colorado, and to Moab, Utah, 
Miss Eastwood. Lower Temperate life zone.. 
65. Astragalus jejunus Watson Bot. King 73 (1871). Phaca Ryd- 
berg. Pods nearly smooth, mottled when in the sun, flattish to a tri- 
fle sulesté ventrally.: faintly . signe tai when fresh, a little later- 
it, very translucent and delicate in 
about 1 cm. long. Flowers al-
