Perennial, much-branched herb, up to 0.6 m high, erect but becoming decumbent with age. Leaves alternate, bipinnatisect, lobes linear, mucronate with hard white mucro, margins irregularly serrate, yellow-green, initially sparsely long-pilose, soon glabrous; petioles semi-amplexicaul, sheathing. Capitula radiate, terminal, solitary, long pedunculate; involucral bracts in 3 or 4 rows, imbricate, outer narrowly oblong to lanceolate, inner broadly lanceolate to ovate, with narrow membranous margins, glabrous. Receptacle flat or convex, paleate, paleae membranous. Ray florets female, corolla white or pale red-purple, sometimes absent. Disc florets many, corolla tube campanulate above, with 5 ovate lobes, pale yellow. Flowering time all year. Pappus absent. Cypselae dark yellow-brown, smooth, lanceolate, flattened triangular, densely white-woolly.
