the leaves, mostly shorter. Plants perennial, with caevpitose 

 Btems prostiate or at least not erect, and having very short 

 internodes, A. inflexus sometimes has longer internoues 2nd 

 ascending stems. Whole plant woolly, shaggy or silvery, 

 with mostly slender hairs always attached by the base. 

 2AB. Pods shaggy, with hairs about straight when dry, inflated, 

 spreading or reflexed. Pubescence of leaves and ped.n- 

 cles neither woolly nor crisped, appressed. Acaules-cnt or 

 with rudimentary stems, never growing in large and pros- 

 trate mats. Cld petioles coarse, stiff, persistent. Pedun- 

 cles neither longer than the leaves nor absent. Newbenyenses. 

 Pod"^ abruptly arcuate at tip, rarely twice as long as wide. 



Flowers purple or purple-tipped. 175 Newberryi 



Pods acuminate lanceolate and equall3' arcuate. Flower- 



cream-colored, or lead-colored when dry. 176 Eurekensis 



2A2E. Fees densely shaggy or wPite-woolly (so much so as to 

 mostly conceal the surface, not inflated (except in the A. 

 funereus group), cartilaginous, not noticeably reflexed, 

 opening only ct tip. Leaves and petioles soft and slender, 

 soon decaj irg ( exctpt in A. ccccineus). Internodes not 

 longer t^an the stipules (except in forms of A. inflexus). 

 Pedicels very short and thick. Plants acaulescent only in 

 reduced forms, mostly prostrate and matted with slender 

 but shore stems. Pubescence rath-*r spreading, of soft and 

 very fine, kinked, white, tangled hairs like wool (scarcely 

 so in the A. funereus group). Flowers narrow, with cylin- 

 drical tube and short teeth. Leaflets 5 to many pairs, 

 mostly contiguous, not thick, flat. Coccinei. 



2A23C. Pubescence very dense and white, the hairs tangled 

 and v/avy but relatively short and not distinctly woolly 

 but rather spreading and appearing as if woolly or short- 

 shaggy, under the microscope the hairs are mostly parallel. 

 Flowers large, very narrow, with long claws, brilliant- 

 pink-purple or red, miostly bracteate at base, almost 

 sessile on very stout pedicels. Calyx teeth subulate and 

 about 3 mm. long, shaggy, hooked, broad, the short pubes- 

 cence shaggy but barely concealing the surface. Calyx 

 a little inflated, the upper side somewhat convex. Leaves 

 rarely 7 cm. long, narrow. Peduncles very stout and 

 shorter t.ian the leaves. Plants of the lower edge of the 

 Lower Temperate life zone, growing on rather bare 

 ridges in poor soil inclined to be alkaline but very well 

 drained, in the Death valley region. 

 Pcds about 3 cm. Icng. Flowers red even when dry. 



177 coccineus. 

 Pods about 5 err. long. Flowers bluish when dry. 178 funereus. 

 2A2B2C. Pubescence of very fine, sle.ider, kinked, woolly 

 hairs. Claws of petals not exscrttd. Neither peduncles 

 nor petioles persisting. Pods opening at tip along both 

 sutures. 

 2A2E2CD. Stipules, bracts and calyx lobes not filiform, 

 nor lax at tip, the stipules and bracts large and the calyx 

 lobes short. Wings longer than k«el. Leaflets round to 

 oval-obovate and rounded. 179 Utahensis. 



2A2E2C2D. Stipules, bracts and calyx lobes mostly taper- 

 ing into thread-like and lax tips. Pubescence inclined 

 to be silky-woolly and rather long. Leaflets normally 

 acutish at both ends, and rather diamond-shaped. Stems 

 slender though sometimes very sliort to almost acaules-
