long-lanceolate to elliptical, apiculate, flat, long-petiolulate, nearly 
contiguous, the largest about 2 cm. long. Stems stout, decumbent, 
2-3 feet long, often 5 mm. thick, flexuous, with internodes rarely 5 cm. 
long. Stipules subulate, lax, thin, hardly 1 cm. long, with threadlike 
tips. Pubescence softly white-villous all over, the stems white, the 
leaves greener. A very robust plant of the foothills near Santa Mon- 
ica California, Braunton. Tropical life zone. This isa most unexpec- 
ted addition to the group. 
131 Astragalus Lyallii Gray Proc. Am. Acad. 6 195 (1864). Pha- 
ca Piper. Pods very variable, straight, pungently acute, flat at tip, 
narrowly sulcate dorsally, about 3 mm. high and 1-2 mm. wide, close- 
ly reflexed, splitting the calyx, hoary or smooth, finely cio:s-nerved, 
about 5 mm. long, Z-celled to tip, triangular-ovate to oblong-lanceo- 
late (rarely oval), with cross-section narrowly triangular-co:date to 
broadly cordate-ovate, with ventral suture raised and thick, pod but 
little convex on the dorsal side. Flowers white or tinged with purple, : 
about 6-7 mm. long, nearly sessile. Banner ovate, often purple-striate 
4-5 mm. long, abruptly arched at end of tube to nearly erect, with 
sides-much reflexed so that outline is nearly linear. Wings oblong- 
lanceolate, but little arched, narrower than keel and from 2 mm. longer 
to only a little longer than keel, 3 nim. shorter than banner. . Keel with 
nearly straight base, about 3 min. long and high, very abruptly roun- 
ded at the end to more than erect, the tip being deltoid, obliquely trun- 
cate, colored, not surpassing calyx teeth. Calyx tube turbinate to cam- 
panulate, about 2 mm. long, narrowed below, blackish with shaggy hairs 
about as long as tube, the filiform teeth very lax and often twice the 
tube. Pedicels slender, about 1 mm. long in fruit. Bracts subulate, 
lax, about 2-4 mm. long. Peduncles slender, rarely 3 cm. long. Flo- 
ral rachis erect, tapering, oiten 1.dm. long. Central leaves about 6 
cm. long, mostly sessile, spreading, rather broad. Leaflets 6-8 pairs, 
not contiguous, 1-1.5 cm. long, narrowly elliptical to almost linear, 
acute, softly appressed-hoary-silky with very fine and long hairs. 
Stems nearly erect, a foot or two high, flexuous, with peduncles in 
most of the axils, more hairy than the leaves, with internodes 3-5 cm. 
long, nearly simpie. Stipules inconspicuous, small with threadlike tip. 
Whole plant silvery-silky. Some forms shade toward A. Spaldingii in 
shape of pods and pubescence but the pods are conspicuously exserted 
from the calyx, always reflexed. Calyx much smaller and lobes lax 
and relatively longer than in the other species. Stems from woody 
roots. From Glenn’s Ferry Idaho to the lower Columbia Basin, grow- 
ing on prairies and in sandy places. Lower part of the Middle and 
upper part of the Lower Temperate life zones. : 
Astragalus Lyallii var. caricinus N. Var. Leaflets linear lanceo- 
late and acuminate, very sharp-pointed, 1-2 cm. long. Calyx lobes àl- 
most capillary and much longer than the tube, lax and long-villous. . 
Pods mostly reflexed, nearly 1 cm. long, half-oval-ovate to oblong- 
lanceolate, acuminate, thin, often nearly smooth and cross-veined, sui- 
cate to the middle (less so below) and with septum intruded to the 
ventral suture or more, very much laterally flattened, and with cross- 
- section cuneate with a cordate base, with both suturcs arched but the 
dorsal the more. Plants about a foot and a half high and densely tuf- 
ted from a woody root. This grows on sand dunes at Glenn’s ‘erry 
. Idaho on hillsides. There are all sorts of intergrades. Lower Tem- 
. perate life zone. The pods are shaped like a buckwheat or Carex grain 
_ (but not as wide as the former) and hence the name. sate
