longer than wings and 2 mm. longer than keel. Wings obliquely 
obovate a trifle arched 1 mm. wide, as wide as keel, very 
obtuse, concave to keel, spreading, nearly horizontal and the right 
hand one the more, at tip. Kee] about 1 mm. long abruptly arched to 
& half circle, very obtuse, Calyx tube about hemispherical, deeper 
cleft above, 1-1.5 mm. long, nigrescent, a trifle laterally flattened, ob- 
lique at tip, with the deltoid teeth shorter than the tube. Pedicels slen- 
der, reflexed, about 2 mm. long. Bracts very thin and hyaline, shorter 
than the mature pedicels, triangular. Peduncles about 1 dm. long, 
often shorter than the floral rachis, in all the upper axils, sulcate. 
Leaves widely spreading, 3-10 cm. long, very delicate and quickly 
wilting, nearly sessile, with filiform rachis. Leaflets 6-12 pairs, 
linear-oblong to oval-ovate distant or not contiguous, 4-12 mm. long, 
conspicuously petiolulate, obtuse to retuse, 2-5 mm. wide, nearly 
smoooth . Stipules minute, subulate, not connate. Stems biennial or 
short-lived perennials, 2-3 ft. high and racenosely branched from a 
woody and erect root. This has the habit of A. Rusbyi and the deli- 
cate and erect Daleas. The pods are nearly the shape of A. sesquiflo- 
rus (but reversed) and leptaleus and Guatamalensis, but is not related 
to any of them unless it be the latter. It grows among the oaks 
along streams in the lower edge of the Middle Temperate life zone, 
in the Sierra Madres of Chihuahua Mexico, at 6000 to 9500 ft. alt. 
Blooming in fall. 
Astragalus scalaris var. quercetinus n. var. Pods conspicuously 
Stipitate, the stipe about as long as calyx. Pedicels twice as long. 
Leaflets elliptical-ovate to oval-ovate. Plants about 3 feet high and 
with innumerable branches. Sierra Madre Mts, Chihuahua. San 
Diego Canon Sept. 16, 1903, Middle Temperate life zone. All sorts 
of intergrades occur. 
51. Astragalus Wardi Gray Proc. Am. Acad. 12 55 (1876). Phaca 
Rydberg. Pods almost oval, inclined to be triangular-acute at both 
ends, straight, scarcely at all oblique. smooth, mottled, with round cross 
section except for a slight groove ventrally, the minute tip flattened 
and cuspidate, seed-bearing only in the middle and ventral suture in- 
truded about one half mm., inclined to have a round false-stipe 1-2 
mm. thick by the narrowing of the pod at the calyx but without any- 
thing but a mere rudiment of a true stipe. Flowers white or nearly so 
about 5 mm, long, ascending but soon pendent, arched as in A. pictus. 
Banner about 3 mm. long, arched abruptly to fully erect at calyx tips, 
greenish-white with tinge of yellow, purple-streaked below with fine 
lines; groove about 2 mm. wide and forming one third circle, about 1 
mm. deep, a little shallower above and a little narrowed and deeper 
below; sides reflexed opposite the calyx tips a very little; blade oblong, 
to oval, rounded at tip and with sharp notch. Wings oblong-ovate, 
arched 45 degrees, narrowed at the almost acute and incurved tip 
about 2 mm. wide and 1 mm. longer than keel, and nearly 2 mm. 
shorter than banner, close-pressed to near the keel tip, then con- 
cave to it and the left hand one spreading with the lower edge 
turned out, the other bent over keel at tip and close-pressed to tip, 
not streaked. Keel a little deflexed at calyx tips, at the end sharply 
incurved to 115 degrees obtuse. vollow-tipped, barely 1 mm. longer 
than calyx, about 2 mm. high, Calyx obliquely campanulate, the tube 
about 2 mm. long, with base straight, and the upper side arched to 
near a quarter circle, attached on the lower acute corner which is 
fleshy, cleft a little deeper above, with a broad sinus, obcompressed at 
tip, with scattered black hairs, teeth subulate to triangular and about 
as long. Pedicels in fruit filiform, often 4 mm. long and longer than 
the delicate triangular bracts. Peduncles axillary throughout, fil 
_ shorter than the leaves, the floral rachis at least as long, 5-15 flowered. — — 
Leaves rarely 2 dm. long, lax and thin, the upper almost sessile.  —
