Collini. 139 
COLLINI 7. 
Pods somewhat fleshy when green, coriaceous (almost 
cartilaginous in A. Gibbsii,) not inflated, linear or nearly so, 
elongated, stipitate but stipe not Jointed nor the pod jointed to 
it, 1-celled and with sutures not at all intruded, laterally flat- 
tened (rarely obcompressed in the middle in A, Gibbsii), in- 
clined to split first at base along both sutures and through the 
the stipe but with valves not curling, with both sutures thick 
and raised externally and rib-like, pod acuminate or triangu- 
lar-acute at both ends, flat-beaked, areuate (rarely straight-in 
A. collinus and Tweedyi) often to a-cirele or more, wtih the 
ventral suture concave and the tip in line with it, opening first 
at base, rarely at tip. Flowers cream-colored, 7-15 mm. long, 
. racemose and mostly densely so, variously reflexed, stubby. 
Banner mostly much recurved and fleshy at base, with wings 
inclined to extend beyond it and these mostly much’ longer 
than keel, banner blade often shorter than calyx tube. Keel 
short and long-elawed, with tip erect abruptly or a little more 
than erect, about 3 mm. high, Calyx short-eylindrie to campa- 
nulate, inclined to be a little inflated, hyaline, cream-colored, 
very oblique at both ends, the upper side arched to nearly 
one third eirele, the lower side straight, inclined to be saccate 
on the upper corner at the insertion and inserted on the lower 
eorner which is mostly cut away a little there, the calyx re- 
flexed and mostly inserted at right angles to the pedicel which 
is relatively slender, erect, and as long as the minute and 
mostly subulate bract, 1-3 mm. long. Peduncles in the upper 
axils. Internodes many and short, the uppermost the short- 
est. Leaves short, 2-10 em. long, widely spreading, almost 
sessile. Leaflets 4-7 pairs, nearly contiguous, long-petiolulate, : 
thiekish but not fleshy, from nearly round or obovate to nearly 
linear, truncate to deeply notched at tip, not over 1.5 em. long, 
often folded, subalternate, minutely woolly (smooth in A. por-. 
rectus) with fine white hairs which are attached by the larger 
base and then arch over and with tips variously appressed 
and wavy bu tnot abruptly appressed at attachment as is 
the case with most species with appressed hairs . Stems 
flexuous, slender, erect or nearly so, much tufted, more pub- 
escent than the leaves, 1-2 ft. high, with branches often 
widely spreading. Stipules and bracts small or minute, rigid, 
greenish. Perennials of the Columbia Basin and along the 
eastern side of the Sierras only. Middle and Lower Temper- 
. ate life zones, growing on grassy or sagebrush plains and -
