Herbs, perennial, 2–5 dm, monoecious. Stems erect, short-pubescent and hirsute. Leaves: petiole 0.2–1 cm; blade rhombic-ovate to ovate, or proximal suborbiculate, 2–6 × 1–3 cm, base acute to rounded, margins serrate to crenate-serrate, apex acute to acuminate.

Pistillate bracts (normal flowers) loosely arranged (inflorescence axis visible between bracts), 8–12 × 7–11 mm, abaxial surface sparsely pubescent and stipitate-glandular; lobes (3–)5–7(–8), triangular to attenuate, 1/5–1/3 bract length or terminal lobe longer; of allomorphic flowers absent. Pedicels of allomorphic flowers 3–5 mm. Pistillate flowers: pistil 3-carpellate (normal flowers), 2-carpellate (allomorphic flowers); styles multifid or laciniate. Capsules muricate, pubescent; allomorphic fruits obovoid, 2 × 1.5 mm, muricate, pubescent. Seeds 1.5–2 mm, minutely pitted. 2n = 40 (Mexico).

Plants from the United States have nearly always been called Acalypha lindheimeri, distinguished from A. phleoides on the basis of leaf shape and bract lobing. Although plants from Texas generally can be distinguished from plants from central Mexico southward, plants from intervening regions in the United States and Mexico include a full range of intermediates (G. A. Levin 1999b).
