164 Reventi-Arrecti, 
‘spreading, leaflets thin and inclined to be notched at the end, bright- 
green and apparently smooth, under a lens the young parts are sparse- 
ly ciliate or appressed-hairy. Internodes very many, with the upper 
ones often as short as the leaflets, and so the leaves are congested a- 
bove. Whole plant nearly smooth except the nigrescent calyx. Found 
in Snake River canon near Ballard’s Landing and on Pine Cr,, and on 
the grade below Cuprum, Idaho, on rocky slopes, Middle Temperate 
life zone. First collected by Cusick in 1898, then by myself (pods on- 
ly) in 1899, This species reminds one, as to habit, of A. crassicarpus, 
accidens, and Beckwithii, but its relationship is here, and accidens, 
though less related, can hardly be placed elsewhere. 
120 Astragalus Bolanderi Gray Proc. Am. Acad. 7 337 (1868) A. 
supervacaneus Greene. Pods with body about 1 cm. long (the slender 
stipe 4 mm. long), about 5-7 mm. wide and 5 mm. high, thin-coriaceous 
to almost chartaceous, oblong-lanceolate, evidently inflated, cordate 
at base, shortly triangular-acute at the flat tip (which is as high as long 
aud evidently declined only when young), indistinctly cross-nerved and 
but little reticulated, arched to a half circle or more and inserted at 
right angles to the stipe: partition intruded to the ventral suture from 
base to middle of pod: cross-section about ©-shaped. Flowers white 
or cream-colored, with rather short claws, about 1 cm. long, ascending 
and almost capitate, rather few, sometimes tinged with purple. Ban- 
ner ovate, gently arched to nearly erect about 2 mm. beyond calyx tips, 
4-6 mm. long, inclined to be stubby and short, 2-4 mm. longer than the 
keel, with sides reflexed about 1 mm. wide below. Wings nearly lin- 
ear, straight, fully 2 mm. longer than keel. Keel straight, about 4 min 
long, with erect tip which is abruptly arched, 3 mm. high, triangular, 
and slightly if at all colored, long-clawed. Calyx ashy, about 5 mm, 
long, cylindrical but a little narrower below, rounded at base and some- 
what obliquely inserted, straight, with slender and subulate teeth une- 
qual and a little shorter than the tube. Peduncles in the upper axils 
only. Pedicels as long as the ovate bracts. Leaves about 1 dm. long, 
ascending. Leaflets distant, linear-lanceolate, ashy with fine, crisped 
and woolly appressed hairs. ' Internodes 4-5, 2-5 cm. long, not shorter 
above. It grows in poor, gravelly and rocky soil, in the higher Sierras 
from King’s River north nearly to Shasta in the Upper Temperate life 
zone. 
121 Astragalus accidens Watson Proe. Am. Acad. 22 471 (1887). 
Pods half-oval to almost lunate, also half-oval to half-round longitudin- 
ally, and broadly elliptical in cross-section, shortly-acute at both ends, 
little pulpy, a trifle inflated, nearly smooth but ovary white-pubescent, 
sometimes sulcate dorsally, finely reticulated, 7-12 mm. long, 5-7 mm, 
high, mostly horizontal: cross-section ovate to elliptical but sometimes 
nearly round: ouly the ventral suture raised and thick externally and 
straight to concave. Flowers reflexed. Banner narrow, erect, 1-15 
em. Jong, ascending beyond calyx tips to 45 degrees, with sides re- 
flexed. Wings oblong, 3 mm. longer than keel, 1 mm. wide. Calyx 
reflexed, campanulate, 7 mm. long, Bracts 1 mm. long, equal to the 
pedicels. Peduncles 1-1.5 dm. long. Racemes short. Leaf rachis 8-15 
cm. long. Leaflets 10-15 pairs, truncate to retuse, 1-1.8 cm. long, ap- 
pressed-pubescent below and glabrous above. Plants sparingly pubes- 
cent except the ashy pods. This grows in open woods, Oregon. Cow 
Creek, Howell. Glendale, Jones. 
Astragalus accidens var Hendersoni (Watson Proc. Am. Acad. 22

des Greene. A. pruniformis Jones. Pods smooth, obtuse at both 
ends, very fleshy, a trifle oblique, 8-23 mm. long, 7 mm. wide. 9 mm. 
high, rather deeply reticulated when dry, indifferently spreading to re- 
flexed, not inflated, from nearly oval to oblong-oval, apiculate, with 
both sutures raised, the ventral nearly 1 mm, thick and the dorsal thin.
