Treatment appears in FNA Volume 4. Treatment on page 297. Mentioned on page 278.

Stems erect to ascending, usually much-branched, 0.2–0.7 (–10) dm, densely farinose. Leaves nonaromatic; petiole 0.5–2 (–3) cm, shorter than or equaling leaf-blades; blade ovate to rhombic-ovate, 1–3.5 (–4.5) × 1–3 (–4) cm, base broadly cuneate to abruptly truncate, distinctly 3-lobed, margins dentate to ± entire, apex obtuse (rarely subacute), grayish, usually densely farinose on both surfaces. Inflorescences glomerules in terminal and lateral compound spikes, 2–19 cm; glomerules subglobose, 3–4 mm diam.; bracts absent. Flowers: perianth segments 5, distinct nearly to base; lobes ovate, ca. 1 × 1.1 mm, apex obtuse, densely farinose, keeled, covering fruit at maturity; stamens 5; stigmas 2, 0.2 mm. Utricles depressed-ovoid; pericarp nonadherent, smooth to indistinctly granulate. Seeds lenticular to compressed-subglobose, 0.8–1.25 mm diam.; seed-coat black, smooth or faintly reticulate. 2n = 54.
