Erect, perennial herbs with tufts of annual stems from underground rootstock. Stems unbranched or sparsely branched, becoming pedunculoid upwards or corymbosely branched upwards, ribbed, glabrous or sparsely to densely villous, often densely villous immediately below capitula, with tufts of hairs in leaf axils. Leaves sessile, lower opposite or subopposite, upwards alternate, sometimes alternate all along, narrowly to broadly ovate, sometimes some upper narrowly elliptic, rarely some narrowly obovate, decreasing in size upwards and passing into peduncular bracts, apex acuminate or attenuate, sometimes acute, base subcordate, rounded or obtuse, especially in lower leaves, or narrowly to broadly cuneate in upper leaves, margin sometimes whitish or paler than rest of blade, entire or sometimes in some leaves sparsely and minutely serrulate in upper part of leaf, glabrous or sparsely to more densely villous, blade glabrous or sparsely to more densely villous, hairs sometimes concentrated along main veins on upper surface, 3(5)- veined from base. Capitula heterogamous, radiate, solitary or in open, few-headed corymbs. Involucre hemispherical. Involucral bracts in (2)3 or 4(5) rows, subequal, inner grading into outer paleae. Receptacle paleate, paleae boatshaped with a dark apex, back sometimes with narrow membranous wing. Ray florets zygomorphic, female, fertile, rarely some neuter in a capitulum, arranged in 1, 2 or 3 rows; corolla white, cream, creamy, cream-white, yellow, lemon-yellow, sulphur yellow or pale greenish yellow; with or without staminodes. Styles exserted, bifurcate, lobes equal or sometimes unequal, rarely undivided. Ovaries obovate-trigonous, those of second and third rows of ray florets laterally compressed similar to disc floret ovaries, glabrous. Ray cypselae usually obconical-trigonous, those of second and third rows of ray florets obovate and laterally compressed, straw-coloured, glabrous, ribbed, each angle(margin) ending in a pappus awn. Ray pappus dimorphic, consisting of awns and scales in between. Disc florets actinomorphic, bisexual, fertile, many; corolla dark (purplish), tubular, 5-lobed. Anthers 5, exserted, apical appendages narrowly ovate, bases caudate and calcarate, tails ciliate. Styles bifurcate, sometimes exserted but mostly hidden within anther ring. Ovaries obovate, laterally compressed, glabrous. Disc cypselae obovate, laterally compressed, ribbed, glabrous. Disc pappus dimorphic, consisting of awns and smaller scales in between awns.
