19 MALACI. 
Pods narrowly oblong to nearly linear, partly to wholly 2- 
celled, inclined to be fleshy, not inflated, rather laterally flatten- 
ed to conspicuously obcompressed, pubescent but never woolly, 
smooth in A. succumbens, sessile, 2.5-7 cm. long, mostly reddish 
and racemose, capitate in the A. Parryi group. Stems tufted, 
erect, spreading, with few internodes but never acaulescent. Pe- 
duncles about terminal. Calyx teeth and bracts inclined to be 
lax and long. Flowers large, about 2 cm. long. Calyx eylindri- 
caland with teeth over half the whole. Petals broad, short- 
clawed, Leaves long and narrow, with many large, broad and 
obtuse to barely apiculate leaflets, and large and hyaline stipules 
which are not connate above. Perennials, except A. succum- 
bens, not woody. Pubescence of leaves shaggy, puberulent and 
-only ashy in A. ensiformis, and silvery and appressed in A. 
Layneae. The sections of this group though loosely related are 
nearer to eachother than to other groups. 
KEY. 
A. Flowers capitate, few, white. Calyx almost as wide as long. The 
pods linear-lanceolate, much obcompressed, sulcate dorsally, acumi- 
nate, very fleshy, cartilaginous when dry, about 3 cm. long and 5 mm. 
wide. Plants densely pubescent. Compare this group with the Sar- 
cocarpi. 
Pods not 2-celled, shaggy. 182 Parryi. 
Pods 2-celled, pu erulent. 183 Feensis. 
2A. Flowers shortly racemose and few. Pods broadly linear, round 
in cross-section when fresh, not sulcate, apiculate, 3-5 cm. long, ‚pu- 
berulent, reddish. Plants only puberulent, with the habit of A. ciba- 
rius. ; 
184 ensiformis. 
3A. Flowers racemose, rather many: Pods acuminate, often sulcate, 
seldom fleshy, 3-7 cm long, mostly pubescent. Plants strongly pu- 
bescent. Leaflets from about oval to obovate and very obtuse, and 
very pubescent. Stipules large, narrow and acuminate. 
Pods much laterally flattened, not long-acuminate, 6-8 mm. high, shaggy. 
Flowers pink-purple. Pubescence shaggy. 185 malacus. 
Pods not laterally flattened, long-acuminate, not over 3 mm. high, not 
shaggy. Flowers white with purple tips. Pubescence not shaggy. 
186 Layneae. 
4A. Pods linear, not acuminate, arcuate, much laterally flattened and 
with concav” sides, deeply sulcate dorsally and 2-celled, the ventral 
suture raised as a thin wing, sessile and jointed to the calyx, papery, 
not inflated. Flowers about 2 cm. long, in short spikes. Pubescence 
loose, rather coarse, of hairs tapering from a pustulate base. Winter 
annuals of the Columbia Basin. Succumbentes.
