48. Chenopodium salinum Standley, sp. nov. 
Erect, prostrate, or ascending annual, usually much branched, the branches stout, 1-4 dm. 
long, glabrous; leaves numerous, the slender petioles equaling or shorter than the blades; leaf- 
blades broadly triangular-ovate or oblong-ovate, rarely oblong or lanceolate, 1.5-3 cm. long, 
0.3-1.5 cm. wide, those of the inflorescence little reduced, obtuse at the apex, narrowly or 
broadly cuneate at the base, coarsely sinuate-dentate, the lobes acute or obtuse, pale-green 
and sparsely farinose on the upper surface or glabrate, densely farinose beneath; flowers sessile 
in dense glomerules, these sessile in the axils or forming stout, very dense, leafy spikes 1.5 cm. 
long or shorter; branches of the inflorescence bearing few or numerous villous white hairs, the 
hairs often present also on the young leaves; calyx herbaceous, deeply cleft, the lobes obovate, 
rounded at the apex, imperfectly enclosing the fruit; stamens 5, or rarely fewer: stigmas short; 
pericarp green, free; seed vertical or horizontal, 0.8-1 mm. broad, dark reddish-brown, finely 
tuberculate, shining, the margin obttse.
