Leaves: Leaves basal and cauline, alternate; the first basal (most proximal) leaves withering by anthesis, basal petiolate, blades 3-nerved, lanceolate to oblanceolate (sometimes linear-oblanceolate), 15-30 cm long x 7-20 mm wide; apex acute to acuminate.
Inforescence: Heads single, 26-45 mm in diameter.
Flowers: Corollas pale to deep pink, 10-13 mm long, tubes ca. 10 mm, lobes 5-7.5 x 0.7-1.1 mm. Anthers Purple, 3-3.5 mm long, the column exerted beyond the corolla throat.
Fruits: Cypselae 3.0-3.2 mm long, 1.5-1.6 mm wide, hairy on the ribs at maturity.
