Herbs, erect, silky villous; stems unbranched or sometimes branched at apex, 10-150 cm tall, densely silky sericeous to woolly tomentose. Lower larger and crowded at the base, obovate-spathulate, elliptic or oblong, acute or obtuse, margins irregularly obscurely dentate or serrate-·dentate with blackish indurated teeth, 2-20 x 0.3-0.6 cm, velutinous on the upper surface, densely sericeous to woolly on the lower surface. Heads globose, in axillary and terminal sessile or pedunculate clusters forming a dense panicle or interrupted-spicate inflorescence sessile, 6-10 mm in diam. Involucral bracts straw coloured or distinctly purple tipped, oblong-lanceolate to oblanceolate, 1-10 x 0.5-0.75 mm, acute to acuminate, reflexed at maturity, woolly to glabrate outside. Receptacle slightly convex, alveolate, 2-4 mm in diam., glabrous. Corolla of bisexual florets tubular, 4-4.5 mm long, 5-lobed; lobes triangular, pubescent, corolla of female florets filiform, 4-5 mm long, 3 to 4-lobed, glabrous.
