barely longer than the keel, about 6 mm. long, arched gently from 
calyx to nearly erect, thick, the thin white margins reflexed about 2-3 
mm. wide. Wings oblanceolate and rounded, barely 2 mm. wide. Keel 
very obliquely elliptical, the obtuse tip ascending mostly to 459, 
about 2 mm. wide. Calyx tube about 5 mm. long and 4 mm. high, 
smooth except at the rudimentary teeth, the teeth almost obsolete, 
The filiform pedicels conspicuous, 4-10 mm. long. Bracts nearly 
equaling the calyx. Leaves 1-1.5 dm. long, with very short petioles. 
Leaflets 5-9 pairs, ovate to oblong-elliptical, lighter below and sparse- 
ly pubescent with very short and woolly hairs, often 5 cm. long, 
rounded to notched. Stems stout, 2-3 ft. high, strict, from slender but 
rather woody roots. Occasional from Dakotah and northern Colo- 
-ado in subalpine valleys around the edges of woods to the Arctic, 
northwestward to the head of the Bitterroot in Montana at Alta. 
Not in the Great Basin nor (so far) reported from the western 
edge of the Columbia Basin.

196. 'The necessity for adopting the Phaca alpina L. for the A. fri- 
gidus L., because of the Vienna rules, requires renaming the Astra- 
galus alpinus of Linnzus. For evident reason I do not adopt the 
senseless name astragalinus, nor the already preoccupied A. giganteus 
of Sheldon, another equally senseless name for this diminutive plant. 
Pods as well as flowers capitate or very shortly spicate, 1-1.5 cm. 
long, 3-4 mm. wide, rarely 3 mm, high, obliquely oblong, nearly straight, 
closely reflexed, shortly and abruptly acute at both ends to triangular 
and even acuminate at base, the longitudinal section generally ellin- 
tical from side to side, black-hairy and mostly shaggy, but variable 
with dorsal suture from conspicuously produced half way to a mere line 
within. Flowers 7-12 mm. long, purple-tipped, rarely all purple, can- 
itate when many, sometimes few, and pods reduced to a single 
terminal one or few, or many, generally 6-12 mostly widely spreading 
and soon closely reflexed. Banner obovate to oval, 5-10 mm. long, 
rather abruptly arched to 30 to 90 degrees at calyx tips or 2 mm. 
beyond and when much reflexed seems remote from keel. about 1 mm. 
longer than keel or less, with the obovate and rounded white spot 
conspicuously purple-veined, with sides reflexed most in the middle 
and 2 mm. wide; groove V-shaped and vanishing above. Wings oblong- 
clavate. 2 mm, wide, about 5 mm. long, about as long as or a little 
Shorter than keel, neither grooved nor notched, pale to white, straight, 
or ascending 30 degrees. Keel very large for the flower, straight, 
the base straight and then arched variously but rarely to erect, the 
general outline being clavate and broadly oblanceolate, the tip 3-4 
mm, high and about 3 mm. wide, triangular and rounded to nearly 
acute, about as long as banner and very prominent. Calyx tube cam- 
panulate to hemispherical, a trifle laterally flattened, cleft deeper 
rbove with narrow sinus, a trifle oblique at base but equally inserted, 
about 2 mm. long; teeth triangular, unequal, variable but not as long 
as tube. Pedicels about 2 mm. long and equaled by the hyaline bracts. 
Peduncles subterminal, stout for the plant, 7-10 cm, long, ascending, 
longer than the leaves, very sulcate. Leaves all petioled except the 
uppermost. Leaflets oval to elliptical, 7-10 mm. long, obtuse, rarely 
- retuse, gradually smaller above, mostly 10 (6-12) pairs, the northern 
forms rather silky with sparse, white, long and fine, loosely appressed 
hairs, but the southern forms almost smooth. Stems almost fili- 
form, flexuous, with few long internodes, the lower ones mostly short, 
weak and flat on the ground, or with ascending tips, much branched, 
rarely a foot long, forming loose and open mats. Stipules conspicuous 
green, large. rather deltoid. Very variable plants in size of flowers, — 
length of stipe, and width of pods. European pods are often half as  .
