140. Astragalus Panamintensis Sheldon in Coville Death Valley 
Rep. 87 (1893). Pods about 1.5 cm. long, 3 mm. high and 2 mm. wide, 
fleshy when fresh with walls about % mm. thick but cutting hard, 
eoriaceous when dry, rather deeply sulcate along the middle but not at 
all at either end, with septum intruded nearly through below but not 
at tip, jointed to calyx and almost sessile, minutely purplish-mottled, 
faintly cross-ribbed, ashy, with ventral suture conspicuously thickened 
and raised, the tip straight and almost in the middle, cross section Y- 
shaped when dry, mostly single at the ends of the filiform peduncles. 
Flowers 1.2-1.5 em. long, not broad, white, tipped with purple, banner 
oval-ovate, about 1 em. long, abruptly arched to 90° at calyx tips, 
sides not reflexed, groove narrowly-V-shaped and extending to tip; 
white spot tridentate and oblong, waterlined only. Wings 2 mm. wide, 
3 mm. longer than keel obliquely spatulate, convex to keel, expanded 
part mostly beyond keel, rounded, white below and purple above. 
Keel about 2 mm. long and high, arched to a half circle from very 
base, obtuse, bellied below, Calyx tube nigrescent, a trifle arched, the 
lower side barely concave and the upper side convex, not cleft deeper 
above, narrowly campanulate , about 4 mm. long and 2 mm. high, neither 
oblique nor truncate below. Teeth subulate and about as long. Pedi- 
cels 2-8 mm. long, slender. Twice as long as the ovate bracts. Peduncles 
weuk, arched, 3-5 cm. long. Leaves 7-12 em. long, with filiform rachis. 
Leuflets 4-5 pairs, 4-12 mm. long, linear to almost filiform, acute at 
both ends, rather faleate. Stems rather short and very slender, 4-15 
em. long with internodes 7-10 mm. long, woody at base, the tips erect. 
Pubescence of whole plant rather dense and hoary with short and 
appressed hairs. Growing in broad mats on cliffs. Lower. Temperate 
life zone, in canons. Panamint Mts., California. The old stems endure 
from year to year and the old gray petioles help to give the whole 
a birdsnest appearance, +
