Leaves basal (mostly) and cauline; opposite (proximal) or alternate (mostly); petiolate or sessile; blades spatulate to oblanceolate, margins entire, faces woolly-tomentose. Heads radiate, borne singly. Involucres campanulate, 3–5 mm diam. Phyllaries persistent, 8–13 in (1–) 2 series (reflexed in fruit, distinct, linear to oblong, herbaceous, ± conduplicate, woolly). Receptacles flat or convex, pitted or smooth, glabrous, epaleate. Ray-florets 8–13, pistillate, fertile; corollas yellowish or purplish. Disc-florets 7–12+, bisexual, fertile; corollas yellowish, tubes shorter than or about equaling campanulate throats, lobes 4–5, ± deltate. Cypselae compressed, linear-oblanceolate, (callous-margined) ciliate; pappi persistent, of 2 ± laciniate to nearly entire, often uniaristate scales. x = 19.
