Plants glabrous. Stems erect or ascending, branched, 0.1–0.5 m. Leaves: petiole 1/2 as long as blade; blade oblong-lanceolate to lanceolate-linear, 1–3 × 0.2–1 cm, base cuneate to narrowly cuneate, margins entire, plane or sometimes undulate, apex rounded or obtuse-truncate, mucronate. Inflorescences mostly axillary, but at apex flowers also condensed in terminal spikes or spicate panicles, usually leafy proximally or nearly leafless distally. Bracts broadly ovate, 1 mm or shorter, 1/2 or less length of tepals, apex acute. Pistillate flowers: tepals 5, spreading at maturity, spatulate, clawed, subequal, 2 mm, margins fimbriate, apex rounded or shallowly emarginate; stigmas 3. Staminate flowers: tepals (3–)5; stamens 3. Utricles narrowly oblong, 1–1.4 mm, shorter than tepals, indehiscent. Seeds dark reddish brown to nearly black, lenticular or broadly lenticular, 0.6–0.8 mm diam., smooth.
