Shrubs, 20–80(–150+) cm. Stems erect. Leaves mostly alternate; petioles 0; blades mostly filiform, 15–35(–65+) × 0.5–1.5 mm, sometimes with 3(–5+) filiform lobes, abaxial faces sparsely scabrellous, glabrescent, often vernicose, adaxial faces densely scabrellous (white). Pistillate heads ± intermixed with staminates; florets 1. Staminate heads: peduncles 0–0.5 mm; involucres ± cup-shaped, 1–3(–4) mm diam., ± glabrate, ± vernicose or gland-dotted; florets 5–15+.

Discussion
Variety salsola refers to plants bearing burs with 6–14 wings in 2–3+ cycles, their tips ± spreading to patent; var. pentalepis (Rydberg) Strother & B. G. Baldwin refers to plants bearing burs with 5–9(–13) wings in 1(–2) cycles, their tips ± spreading to patent; var. fasciculata (A. Nelson) Strother & B. G. Baldwin [= Hymenoclea salsola var. patula (A. Nelson) K. M. Peterson & W. W. Payne, an illegitimate name] refers to plants bearing burs with 10–18 wings in 2–3+ cycles, their tips antrorsely ± appressed (see K. M. Peterson and W. W. Payne 1973).
Hybrids between Ambrosia salsola and A. dumosa have been called A. ×platyspina (Seaman) Strother & B. G. Baldwin.
