Plants almost glabrous or slightly pubescent distally, especially when young. Stems erect, green or reddish purple, branched distally, mostly in inflorescence, to nearly simple, 0.4-2 m. Leaves: petiole 1/2 as long as to ± equaling blade; blade rhombic-ovate or ovate to broadly lanceolate, 3-15(-20) × 1.5-10(-15) cm, occasionally larger in robust plants, base cuneate to broadly cuneate, margins entire, plane, apex acute or subobtuse to slightly emarginate, with mucro. Inflorescences terminal and axillary, erect, reflexed, or nodding, usually dark red, purple, or deep beet-red, less commonly almost green or greenish red, leafless at least distally , large and robust. Bracts narrowly spathulate, 2-3 mm, equaling or slightly longer than tepals, apex short-spinescent. Pistillate flowers: tepals 5, oblong to lanceolate, not clawed, equal or subequal, 1.5-3 mm, apex acute; style branches erect or slightly reflexed; stigmas 3. Staminate flowers at tips of inflorescences; tepals 5; stamens (4-)5. Utricles obovoid to elongate-obovoid, 2-2.5 mm, smooth or slightly rugose distally, dehiscence regularly circumscissile. Seeds usually white or ivory, with reddish or yellowish tint, sometimes dark brown to dark reddish brown, broadly lenticular to elliptic-lenticular, 1.2-1.6 mm diam., smooth or indistinctly punctate.
