Annuals, (2-)4-12(-30) cm (usually glabrous but for axillary tomentum). Stems usually 1, erect, simple or branched near bases. Leaves (± fleshy) basal and cauline; alternate; petiolate (basal) or sessile; blades palmately nerved, spatulate or oblanceolate (basal) to lanceolate or linear, margins toothed or entire, faces glabrous or glabrate. Heads radiate, borne singly. Calyculi 0. Involucres ± hemispheric, 3-6+ mm diam. Phyllaries (veiny, often purple-tipped, each subtending a ray floret) persistent, 5-13+ in 1(-2) series, erect (reflexed in fruit), basally connate, elliptic to ovate, subequal, margins herbaceous to membranous. Receptacles dome-shaped to conic (heights equaling or greater than diameters), smooth, epaleate. Ray florets 5-13+, pistillate and fertile or neuter; corollas yellow (laminae conspicuous). Disc florets 12-60(-120+), bisexual, fertile; corollas yellow, tubes ± cylindric, longer than or equaling campanulate to cylindric throats, lobes 5, erect to spreading, deltate to lanceolate; style branches stigmatic in 2 lines, apices truncate-penicillate. Cypselae (stramineous to reddish brown) ± ellipsoid to fusiform, 5(-6)-nerved, ± papillate-hairy between nerves (papillae mucilaginous when wetted); pappi fragile or readily falling, usually of 20-40, white, barbellulate bristles (in 1 series), sometimes 0 on ray cypselae. x = 9.
