Part 1, 1916] CHENOPODIACEAE 67 
Erect shrub, 1.5-4 dm. high, fruticose at the base, much branched, the branches mostly 
simple, erect or decumbent, stout, densely whitish-furfuraceous ; leaves alternate, sessile 
or short-petiolate, the blades entire, oblong, narrowly oblong, or oblanceolate-oblong, 1.5-4 
em. long, 4-10 mm. wide, obtuse or rounded at the apex, narrowly or broadly cuneate at the 
base, rather thin, copiously furfuraceous on both surfaces; flowers dioecious, or rarely monoe- 
cious, in sessile axillary glomerules, forming leafy spikes; fruiting bracts broadly cuneate or 
oblong, 4-6 mm. long, 3-3.5 mm. wide, united to the middle, usually 3-toothed at the apex, the 
terminal tooth largest, or the teeth sometimes more numerous, the sides not appendaged; 
seed 2 mm. broad, yellowish-brown, the radicle superior. 
Tyre Locatity: Along the Platte River.

Atriplex pabularis A. Nelson, Bull. Torrey Club 25: 203. 1898. 
Erect perennial, 2-5 dm. high, suffrutescent and much branched at the base, the stems 
stout, furfuraceous, terete, simple or with a few erect branches; leaves alternate, the blades 
oblong-linear, or the lowest linear-oblong, 2-5 cm. long, 2~7 mm. wide, obtuse or rounded at 
the apex, cuneate at the base, sessile or short-petiolate, often with fascicles of smaller leaves 
in the axils, rather thin, densely whitish-furfuraceous, the leaves grayish; flowers dioecious, 
the staminate in large yellow glomerules arranged in stout, dense, sparsely leafy, narrowly 
paniculate spikes, the pistillate in small axillary clusters, forming simple or paniculate, leafy 
or nearly naked spikes; calyx 5-cleft; fruiting bracts triangular-cuneate, compressed, 4-5 mm.

entire or rarely obscurely denticulate, thick and firm, densely furfuraceous; flowers dioecious, 
the staminate glomerules in dense, stout, sparsely leafy, paniculate spikes, the pistillate in 
few-flowered axillary glomerules, forming simple spikes; calyx 5-cleft; fruiting bracts sessile 
or subsessile, 5 mm. long, longer than broad, indurate, free only at the apex, deeply and 
very irregularly dentate, covered on the back with numerous stout flattened appendages, 
densely furfuraceous, the apex triangular-subulate, shorter than the united portion; seed
