green, minutely denticulate with 3-5 teeth, the sides smooth or rarely slightly tuberculate; 
seed 0.8-1 mm. long, the radicle superior.

Obfone Coultert Mog. in DC. Prodr. 13?: 113. 1849. 
Annual or usually perennial, sometimes suffrutescent at the base, much branched, the 
branches slender or stout, 0.7-10 dm. long, terete, furfuraceous, often glabrate in age, frequently 
tinged with red; leaves numerous, alternate, sessile or short-petiolate, the blades obovate, ob- 
long, oblanceolate, or elliptic, 7-15 mm. long, obtuse to acuminate at the apex, cuneate at the 
base, entire, thin, rather loosely furfuraceous; flowers monoecious, the staminate in rather large 
glomerules, these in the upper axils or in short naked terminal spikes, the pistillate flowers 
in small axillary clusters; fruiting bracts sessile, united to the middle, not compressed, 2-3 
mm. long, the margins green, deeply and acutely dentate, the terminal tooth longest, the sides 
nerved, not appendaged; seed 1.5 mm. long, brown, the radicle superior. 
Type LocaLity: California. 
Distrisution: Near the coast, Los Angeles County, California, to northern Lower California 
and on the adjacent islands. 
57. Atriplex Davidsonii Standley, sp. nov. 
Prostrate annual (?), much branched, the branches slender, terete, glabrate, stramineous, 
1-4 dm. long; leaves numerous, alternate, sessile or subsessile, the blades oblong, oval, or lance- 
oblong, 7-13 mm. long, acute or acuminate at the apex, mucronate, remotely repand-denticulate 
or dentate, or the uppermost entire, obtuse or cuneate at the base, very finely and closely 
furfuraceous, green; flowers monoecious, the staminate in rather large glomerules, these 
sessile in the upper axils or in very short, naked, terminal spikes, the pistillate in few-flowered 
axillary clusters; calyx deeply 5-cleft; fruiting bracts sessile, suborbicular or rhombic-orbicular, 
3 mm. long, united to the middle, compressed, the margins acutely dentate, the terminal tooth 
usually longest, the sides usually bearing 2 slender sharp tubercles, or sometimes smooth, 
1-nerved; seed brown, 1.5 mm. long, the radicle superior.

XV. Elegantes. Erect or decumbent annuals or perennials, copiously furfuraceous. 
Leaves alternate, sessile or short-petiolate, the blades narrow, broadest at or above the middle, 
entire or dentate. Flowers monoecious, in axillary glomerules. Fruiting bracts small, orbicular, 
pedicellate or sessile, strongly compressed, radiately dentate to the base, the sides smooth or 
muricate. Radicle superior.
