Erect annual, 2-8 dm. high, much branched throughout or simple below, the branches

commonly with a short rounded tooth on each side near the base, thick, densely farinose be- 
neath, usually glabrate and bright-green on the upper surface, the upper blades reduced; 
flowers in dense, large or small, glomerules arranged in usually dense, paniculate spikes; calyx 
densely farinose, the lobes obtuse, white-margined, carinate, completely enclosing the fruit; 
pericarp free; seed horizontal, 1 mm. broad, smooth, black and shining, the margin obtuse.

i-nerved, obtuse or acutish, attenuate at the base, entire, thick, pale-green, glabrous or very 
sparsely and closely farinose, the upper blades shorter and narrower; flowers in rather large 
glomerules, these in short, interrupted, broadly paniculate or cymose-paniculate spikes, the
