Leaves malodorous; petiole 0.3–1.5 cm; blade narrowly to broadly elliptic to ovate, 0.5–2.7 × 0.3–1.5 cm, somewhat reduced in inflorescence, base cuneate, apex obtuse, glandular-pilose. Inflorescences lateral cymes or glomerules; glomerules subglobose, 1.2–2.5 mm diam.; bracts leaflike, 3–4.5 mm, elliptic, margins crenate-dentate, apex obtuse. Flowers: perianth segments 5, distinct nearly to base, distinct portions narrowly elliptic to narrowly oblong, 0.6–0.7 × 0.2–0.3 mm, apex acute, normally rounded abaxially, usually glandular-pilosulose, becoming crustaceous and white in fruit; stamens absent or 1; stigmas 2. Achenes ovoid; pericarp adherent, membranaceous, slightly rugose. Seeds reddish brown, ovoid, 0.5–0.7 × 0.5–0.6 mm, margins keeled or rounded; seed coat smooth.
