118 Inflati 
not connate, Sicms rather stout and sulcate, 2-3 ft. high, with inter- 
nodes rarely 3 cm. long, flexuous, from a woody base. Pubescence 
variably hoary. Lower Sacramento and San Joaquin valleys and over 
to Monterey and San Luis Obispo. Not often collected. 
72. Astragalus curtipes Gray Proc. Cal. Acad. 3 103 (1868). A. 
leucopsis var. curtipes Jones, 'Tragacantha Kuntze. Pods half-oval- 
ovate, 3-4 cm. long and 2 cm. wide, sulcate ventrally, sharply triangular- 
acute, truncate at base or very abruptly contracted into a stipe as long 
as calyx and set at right angles to it, nearly erect, translucent and 
very thin and greatly inflated, rather few on a short rachis. Flowers 
white, with exserted claws, in a short spike 2-4 cm. long, soon reflexed 
but calyx ascending in fruit. Banner broadly elliptical, 7-8 mm. long, 
arched remotely from calyx to 45 degrees, with sides reflexed about 
1 mm. wide in the middie, about 2 mm. longer than wings, not very 
fleshy. Wings broadly linear, obtuse, arched a little, veiny, about i 
mm. longer than keel. Keel arched from base to about a half circle, 
very obtuse, about 4 mm, high and long. Calyx tube campanulate, 4 
mm. long and 3 mm. high, rather truncate at base and inserted near 
the lower corner, cleft deeper above and oblique, the triangular nig- 
rescent teeth a little unequal and a little over half as long as tube. 
Pedicels stout, about as long as the ovate to lanceolate bracts, 2 mm. 
long. Peduncles 1-2 dm. long, 3-4 times as long as fruiting rachis. 
Leaves slender, and not rigid, 6-10 cm. long, narrow, with slender 
rachis, and petioles even the upper 2 cm. long. Leaflets broadly linear, 
not thick, 1-1.5 cm. long, rounded, not contiguous, about 15 pairs. 
Internodes rarely 3 cm. long. Stems rather slender, erect or ascending 
from a woody base, often with very short internodes and leaves con- 
gested later in the season, 1-2 ft, high. Stipules conspicuous, hyaline, 
connate throughout, often 1 cm. long. Pubescence very minute and 
ashy. San Luis Obispo California. This has been much confused. It 
is described by Gray as having pendulous pods, but this seems to be due 
to the reversal of the pods which sometimes occurs in pressing. The 
leaflets are described as retuse and 13-33, they are seldom notched and 
the pairs are many. Most of the material referred to this belongs with 
leucopsis. 
73. Astragalus leucopsis T. & G. Fl. 1 694 (1840) as Phaca and 
Torr. Mex, Bound. 56 t. 16 (1859). Phaca canescens Nutt., Tragacan- 
tha Kuntze. Pods oblately half-oval and very obtuse at both ends, 
merely apiculate and about 2.5 cm. long and 1.5 em. wide in the 
type, with the ventral suture somewhat arched and sulcate, papery 
and translucent, abruptly rounded to the stipe which is about 1 cm. 
long, cross section seemingly about round but a little flattened above, 
but really triangular-obcordate when fresh, about pendent. Flowers 
1-1.5 em. long, rather thick and in the type stubby with the banner 
but little longer than the wings, and ascending about 45 degrees 
to 90 degrees remote from calyx tips, greenish cream-colored, loose- 
ly spicate. Banner boardly ovate, with sides reflexed above and 
6-8 mm. long, petals with claws inclined to be exserted. Wings 
narrowly obtuse, nearly Straight, close pressed to keel and then 
flaring above, arched a little, about 2 mm, wide and 2 mm. longer 
than keel or less, half-oblanceolate. Keel about 5 mm. long, with 
rather convex base and then abruptly rounded to erect, the tip tri- 
angular, obtuse and about 3 mm. high. Calyx hyaline, inserted on 
the lower corner and rather truncate but not oblique when fresh, a 
little narrowed at mouth and cleft deeper above, a little laterally 
flattened. about 3 mm. long and nearly as high, teeth subulate, un- 
equal and little longer than half the tube. Pedicels stout, about 2 _ 
Jam, long and as long as the triangular-subulate greenish bracts with 
. reflexcd tips. Peduncles strict, often a foot long, sulcate, rather 
lone, nearly sessile, with slender rachis. Leaflets elliptical, mostly 
ed, flat and rather thin, long-petiolulate and cuneate at base,
