Cauline leaves (gradually reduced distally) narrowly linear, 5–60 mm, distalmost flagged. Heads 2–8(–10) in subcapitate arrays. Involucres: staminate 4–5 mm; pistillate 4–6.5 mm. Phyllaries distally light brown, dingy brown, or olivaceous (apices acute-acuminate). Corollas: staminate 2.5–3.5 mm; pistillate 2.5–4 mm.
