Plants glabrous. Stems erect or ascending (sometimes prostrate), stramineous or suffused with red, branched at base, sparsely branched to simple distally, 15-30(-60) cm. Leaves: petiole 1/2 as long as to equaling blade; blade ovate or rhombic-ovate, 1-2.7 × 0.5-1.5 cm, base cuneate to broadly cuneate, margins entire, plane or slightly undulate (rarely erose), apex obtuse, rounded, or broadly cuneate, with mucro. Inflorescences axial glomerules from base of plant to tip, interrupted at nodes or crowded in terminal, leafy spikes. Bracts lanceolate-ovate to lanceolate, shorter than tepals, apex acute. Pistillate flowers: tepals 5, not imbricate, distal parts expanded, oblong-spatulate, subequal, 1.1-1.6(-2.1) mm, scarious, margins entire, apex obtuse or rounded, with excurrent midrib; style branches erect; stigmas 3. Staminate flowers: basal and scattered on lateral shoots; tepals 4-5, oblong-ovate, equal, 1.2-1.6 mm, apex acute to acuminate; stamens 3(-4). Utricles brownish at maturity, obovoid to obpyramidal, slightly biconvex, 1.5-1.7 mm, longer than tepals, rugose to tuberculate, dehiscence regularly circumscissile. Seeds black to reddish brown, lenticular to subglobose, 1-1.2 mm, smooth, shiny.
