Annual herb 20 cm - 0.8 m tall Stem: upright, unbranched to branched above, moderately to densely white-mealy. Leaves: alternate, upright to ascending, on a 0.4 - 1 cm long stalk, 1.5 - 4 cm long, 0.4 - 1.5 cm wide, linear to narrowly lance-shaped to narrowly egg-shaped with a tapering base and pointed tip, typically three-veined, sometimes with a pair of basal lobes, thick, somewhat fleshy, sparsely to densely white-mealy beneath. Inflorescence: a small, dense cluster of flowers (glomerule), which together form upright or ascending spikes, of which form a larger inflorescence (panicle), white-mealy. Flowers: greenish, small, with five nearly distinct sepals and no petals. Sepal lobes to 1 mm long, oblong egg-shaped with a blunt, rounded, or shallowly notched apex, prominently keeled along midvein, densely white-mealy. Stamens five. Stigmas two. Fruit: one-seeded (utricle), surrounded by the persistent, spreading sepals, egg-shaped, thin-walled. Wall (pericarp) loose and easily separable from the seed. Seed horizontal, black, shiny, 1 - 1.4 mm wide, spherical, round-margined, wrinkled.
