2A2B. Flowers in snikes, white or cream-colored, about 1.5 cm. 
long, closely reflexed. Keel large and not purple-tipped, very 
obtuse and rounded. Wings short. Pods with dorsal suture thick- 
ened within but not raised as a thin edge. Stipules very 
large and leaf-like, fully 1 cm. lang, reflexed, thin, obtuse, or the 
uppermost only acutish, oval to oblong. Peduncles subterminal, 
shorter than the leaves. Calyx white, very oblique at both 
ends, cut off at the lower corner and set obliquely to the long 
and filiform pedicel and inclined to be saccate on the upper 
corner, cleft much deeper above, with rudimentary and broadly 
deltoid teeth. Leaves all petioled. Leaflets very large, ellipti- 
cal, contiguous, short-petiolulate, broadly cuneate below, obtuse, 
2-4 cm. long. 
Pods black-hairy. : 89 alpinus. 
Pods green and smooth. 90 Americanus. 
2A3B. Pods distinctly cheoindbestod the cross section triquetrous- 
reniform, somewhat inflated, nigrescent, conspicuously‘ sulcate 
dorsally, with ventral suture straight or a little concave but 
with a convex hump near the tip and tip declined, on, a stipe 
as long as calyx. Flowers in: short racemes or clusters. Stip- 
ules large and leaf-like. Leaflets 10-12 pairs. Plants from 
filiform underground rootstocks.

84. Astragalus Gormani Wight. n. sp. Pods erect and appressed, 
oblong-lanceolate, straight, about 1.5 cm. long and 4-5 mm. wide and 
high, cross section apparently nearly round, partly 2-celled by the 
intrusion of the dorsal suture which is nearly straight, with the ven- 
tral arched, pod splitting the calyx, shortly acuminate, rounded at 
the sessile base, smooth. Flowers white, narrow, nearly 1.5 cm. long, 
reflexed. Banner elliptical, about 1 em. long, abruptly arched to 45 
degrees at calyx tips, with sides reflexed about 1 mm. wide through- 
out, 3-4 mm. longer than wings. Wings lance-linear, 1 mm. wide, 
arched about 30 degrees, 2 mm. longer than keel. Keel with straight 
base and exserted claw, about 4 mm long, 2 mm. wide, the tip abruptly 
rounded to about 110 degrees and deltoid, about 3 mm. high purple. 
Calyx about 4 mm. long and 3 mm. wide, ribbed, rounded at the fleshy 
base and nearly equally inserted, cleft much deeper above, hyaline 
and nigrescent with minute appressed hairs; teeth triangular, spread- 
ing and about 1 mm. long. Pedicels 2-3 mm. long. Bracts very nar- 
row, hyaline and lax, about 7 mm. long. Peduncles stout, 2-3 dm. 
long. Leaves widely spreading, about 7 cm. long, and 4 cm. wide. 
Leaflets smooth, rather glaucous, obtuse, rather distant. Stipules 
subulate-lanceolate, papery and hyaline, adnate and not connate, about 
7 mm. long, spreading, the lower much broader and rather longer. 
Stems about 2 ft. high, with the lower internodes longer, than the 
leaves, ascending, decumbent at base. Whole plant smooth except 
the calyx. Root woody and rather -stout. This has the habit of A. 
aboriginum. It grows in moist ground. on creek banks near Fort 
Selkirk Alaska, Upper Temperate life zone, blooming in : July.

Americanus Gray, A. Shearis Rydberg, Atelophragma Shearis Ryd- 
berg. Pods half-oval, hardly 1 cm. long, 5-7 mm. high and about 3-5 
mm. wide, a little laterally flattened, with cross section broadly 
o9 vate and rarely a little cordate when pod is slightly sulcate dor- 
sally, dark, but white-hairy, obliquely deltoid at each end and with 
stout declined mucro at tip and a minute stipe at base, the ventral
