Plants glabrous or sparsely pubescent in distal parts. Stems erect, green, branched, 0.3-1 m. Leaves: petiole of proximal leaves equaling or longer than blade, becoming shorter distally; blade rhombic-ovate or ovate to elliptic, 3-12 × 2-8 cm, base broadly cuneate, margins entire, apex slightly acuminate to obtuse and faintly emarginate, mucronate. Inflorescences terminal panicles and axillary spikes; panicles erect or often drooping, green, dense, branched, leafless at least distally. Bracts lanceolate, shorter than 2 mm, shorter than tepals, apex spinescent. Pistillate flowers: tepals 5, oblong-spatulate to oblong, not clawed, 1.5-2 mm, apex acute, often very shortly mucronate; style branches strongly spreading, shorter than body of fruit; stigmas 3. Staminate flowers usually clustered at tips of inflorescence branches, sometimes gathered in proximal glomerules (as in A. spinosus); tepals 5, equal or subequal; stamens 5. Utricles ovoid or subglobose, 1.5-2 mm, slightly shorter than tepals, smooth to irregularly wrinkled, dehiscence regularly circumscissile. Seeds dark reddish brown to black, subglobose or lenticular, 0.8-1 mm diam., shiny, smooth. 2n = 64.
