WorldFloraDB - Acalypha rhomboidea

Characteristics

Herbs, annual, 1.5–6 dm, monoecious. Stems usually erect, sometimes ascending, usually sparsely pubescent, rarely sparsely hirsute. Leaves: petiole 0.4–7 cm; blade ovate to broadly rhombic, 2–9 × 0.8–5 cm, base obtuse, margins crenate to serrate, apex acute to acuminate. Inflorescences bisexual, axillary; peduncle 0.1–0.6 cm, pistillate portion 0.7–1.5(–2) × 1–2(–2.5) cm or pistillate bract solitary, staminate portion 0.3–1 cm; allomorphic pistillate flowers rare, solitary in axils near base of stem. Pistillate bracts (normal flowers) loosely arranged to crowded (inflorescence axis clearly to scarcely visible between bracts) or solitary, 6–15 × 9–23 mm, abaxial surface sparsely pubescent and stipitate-glandular; lobes (5–)7–9(–11), lanceolate to triangular, 1/3–2/3 bract length; bracts of allomorphic flowers absent. Pedicels of allomorphic flowers 1–2 mm. Pistillate flowers: pistil 3-carpellate (normal flowers), 1-carpellate (allomorphic flowers); styles multifid or laciniate. Capsules smooth, pubescent; allomorphic fruits obovoid, 2 × 1 mm, spiny, pubescent. Seeds (1.2–)1.5–1.7(–2) mm, minutely pitted.

More

Stems erect, simple or branched, 2–6 dm, glabrous or puberulent in lines or throughout with incurved hairs, often with a few spreading hairs as well; petioles slender, divaricate, those of the larger lvs regularly more than half as long as the blades, these spreading, lanceolate to ovate, with a tendency to be rhombic; pistillate bracts 5–9-lobed, usually stipitate-glandular (visible at 10×) but without long hairs; staminate spikes scarcely exceeding the bracts; seeds 3, 1–2 mm. Dry or moist soil of open woods, roadsides, waste places, and gardens; Que. to N.D., s. to Fla. and Tex. Perhaps better treated as A. virginica var. rhomboidea (Raf.) Cooperr.
