Leaves: basal usually withering by flowering, shorter than cauline; cauline spreading to ascending, sessile, blades linear, falcate, often conduplicate, apices acuminate; proximal 50—90 × 2—7 mm, glabrate to sparsely sericeous; distal somewhat smaller, glabrate except for margins. Heads (2—)4—10(—25) in corymbiform arrays. Peduncles sparsely bracteolate, 1—4 cm, white-villous. Involucres turbino-campanulate, 5—8 mm. Phyllaries in 5—6 series, apices with tufts of hairs, faces sparsely strigose. Ray florets 9—15; corolla laminae 5—8 mm. Disc florets 30—60; corollas 4.5—6 mm, sparsely pilose near base of limbs, lobes 0.5 mm, sparsely pilose. Cypselae fusiform, 3—4 mm, ribbed, faces strigose; pappi: outer of linear setiform scales 0.5—1 mm, inner of 30—40 bristles 4—6 mm. 2 n = 18.
