prostrate, branched, 3–5 dm, pilose and glandular-pilose, or with sessile glands. |
Leaves | aromatic; petiole to 2.5 mm; blade 1.3–4 × 0.6–2.7 cm, base cuneate, margins lyrate-sinuate, pinnatifid, or occasionally entire (in distal leaves), apex acute to subobtuse, glandular-pubescent abaxially. |
aromatic; petiole 0.7–1 cm; blade ovate or elliptic, 1.3–2.1 × 1.1–1.5 cm, reduced somewhat in inflorescence, base cuneate, apex obtuse, glandular-pubescent. |
Inflorescences | axillary cymes, often arranged in terminal thyrses, 12–24 cm, subtended by cauline leaves; bracts absent. |
axillary glomerules; glomerules subglobose, 4–6 mm diam.; bracts similar to cauline leaves, elliptic, reduced to 0.8 mm, margins crenate-dentate, apex obtuse. |

Discussion | Dysphania botrys is related to a species from Africa and southern Eurasia, D. schraderiana (Schultes) Mosyakin & Clemants, which may occur locally in North America as introduced. Dysphania schraderiana has distinctly keeled perianth segments with mostly sessile or subsessile glands. The general inflorescence in D. schraderiana is usually leafy almost to the top, distal cauline leaves are similar to proximal ones (in D. botrys distal leaves are normally much reduced, and the distal portion of the general inflorescence appears nearly leafless). H. A. Wahl (1954) reported that D. schraderiana (as Chenopodium schraderianum) had been grown in Ontario. He did not indicate that it had escaped.
