Leaves basal, filiform, canaliculate, to c. 3–5 cm long; base with dilated membranous margins, often purplish; apex acute, often scabrid; auricles absent. Stem and peduncles distinctly scabrid (with elevated papillae), to c. 0.3 mm in diam. Inflorescence bract short, membranous or leaf-like, usually 2–6 mm long; middle bracts brownish membranous, c. 1.5–2.0 mm long. Inflorescence terminal, usually of umbellate appearance, composed of 1 basal and (0–) 1–7 (–10) pedunculate heads; heads 1–4-flowered cup-shaped; peduncles usually 1.0–3.5 cm long, some with a single secondary branchlet.
