Plants with sparse to scattered hairs c. 0.5–1 mm long but often soon glabrous. Leaves to c. 10 cm long, l:w ratio c. 3–5, 2-or 3-pinnatisect, abruptly dilated basally to form sheath, with scattered hairs or glabrous; primary segments restricted to distal 1/3–1/2, ovate, elliptic or sub-orbicular in outline; secondary segments arising throughout length of primary segments. Capitula 2–4 mm diam.; peduncle to c. 7 cm long at anthesis, c. 0.5 mm diam., sparsely to moderately hairy, becoming glabrous; involucral bracts c. 6–12, broadly elliptic or orbicular, 1.5–2 mm long, rounded apically, glabrous or hairy. Marginal floret corolla broader than long, persistent in fruit. Disc floret corolla c. 1 mm long. Achenes (excluding corolla) 1–2 mm long; faces obovate, pale tan to brown, usually with paler margin.
Grows beside water, typically, sometimes in saline environments such as seashores, in grassland, sedgeland and forest.
