Shrubs or subshrubs, 20–100 cm (finely and densely branched from bases). Stems erect, green, slender and wandlike, striate-angled, glabrate proximally, hispidulous distally (near heads). Leaves present at flowering (reduced, sparse); sessile; blades (1-nerved) linear to linear-lanceolate, 5–17 × 1–2 mm (reduced distally to subulate bracts), margins entire, apices acute, faces glabrous (sometimes minutely papillose). Heads (on racemiform lateral branches) in paniculiform arrays. Involucres funnelform or campanulate; staminate 3–5.2 mm, pistillate 4–6 mm. Phyllaries lanceolate, 1–4 mm, margins scarious, medians green (hispid), apices acute to acuminate. Staminate florets (8–)12–18(–29); corollas 3.3–4.2 mm. Pistillate florets 8–18; corollas 2–2.8 mm. Cypselae 1.5–2.5 mm, 5-nerved, hispid; pappi 4.5–7 mm. 2n = 18.
