Leaves alternate, elliptic to lanceolate, 5-20 cm long, 0.5-6.5 cm wide, acute to acuminate, irregularly serrate to dentate, unlobed or lobed, base cuneate to attenuate or upper stem leaves auriculate. Heads in panicles. Involucres cylindric, 10-20 mm long, 4-8 mm broad; bracts in 1 series or with a few small bracts at base. Disc 3-10 mm broad. Flowers discoid, lobes cream to pinkish, erect, 0.3-0.5 mm long. Nutlets brown, tapered from base to apex, 1.9-2.7 mm long, 0.4-0.7 mm broad, 10-ribbed, pubescent; pappus white, capillary, 10-14 mm long." [1]
