the leaves, mostly shorter. Plants perennial, with caespitose 
stems prostrate cr at least not erect, and having very short 
internodes, A. irilexus sometimes has longer internodes and 
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 pedun- 
cles neither woolly nor crisped, appressed. Acaulescent or 
with rudimentary stems, never growing in large and pros- 
trate mats. Old petioles coarse, stiff, persistent. Pedun- 
cles neither longer than the leaves nor absent. Newberryenses. 
Pods zbruptly arcuate at tip, rarely twice as long es wide. ; 
Flowers purple or purple-tipped. 175 Newberryi, 
Pods acuminate- lanceolate and equally arcuate. Flowers 
cream-cclored, or lead-colored when dry. 176 Eurekensis, 
2A2B. Tec: densely shaggy or white-woolly (so much so as to 
mostly conceal the surface, not inflated (except in the A. 
funereus group), cartilaginous, not noticeably reflexed, 
opening only at tip.‘ Leaves and petioles soft and slender, 
soon decaying (except in A. coccineus). Internodes not 
loan zer then the stipules (except in forms of A. inflexus). 
Pelicels very short end thick. Plants acaulescent only in 
reduced fos, mostiy prostrate end matted with slender 
but saor: . Pubescence rath^r spreading, of soft and 
very fine, ed, white, tangled heirs like wool (scarcely 
so in the A. fun ereus 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 wavy but relatively short and not distinctly woolly 
but rather spreading end zppearing 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, mostly 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 than 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. 
Peds ¿bout 3 cm. long. Flowers red even when dry. 
177 coccineus. 
Pocs ¿tcert5 crr.long. Flowers bluish when dry. 178 funereus. 
2A2B2C. I1bescence of very fine, slender, kinked, woolly 
hairs. Cliws of petals not exserted. Neither peduncles 
nor peticles persisting. Pods opening at tip along both
