Leaves nonaromatic; petiole 0.4-1 cm; blade linear to narrowly lanceolate, or oblong-elliptic, (1- or)3-veined, 1.5-4.2(-6) × 0.4-1(-1.4) cm, thick and somewhat fleshy, base cuneate, margins entire or with pair of lobes near base, apex acute, abaxial surface densely to sparingly white-mealy. Inflorescences glomerules in terminal and axillary panicles, 1-13 × 0.15-0.5 cm; glomerules usually densely disposed, maturing irregularly; bracts leaflike. Flowers: perianth segments (4-)5, distinct nearly to base; lobes oblong-ovate, 0.8-1 × 0.5-0.7 mm, apex obtuse, rounded or emarginate, strongly keeled along midvein, densely farinose, usually spreading from fruit; stamens (4-)5; stigmas 2, 0.2 mm. Utricles ovoid; pericarp nonadherent, smooth. Seeds round, 0.9-1.3 mm diam., margins rounded; seed coat black, rugulate. 2n = 18. Fruiting early summer-fall.

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.
