Heads solitary, radiate; involucres hemispheric, 10–15 mm high; phyllaries in 2 to 4 subequal series, ovate with spreading, acuminate tips; receptacle hemispheric with stiff, pointed, dark scales between the flowers. Ray flowers 8 to 21, sterile, light purple; ligules 1–3 cm long, reflexed. Disk flowers perfect, >100, purplish; corolla 5–7 mm long; style appendages acuminate, short-hairy.
