Leaves basal and/or cauline; opposite (sometimes whorled) or alternate; petiolate or sessile; blades (pinnately nerved or 3- or 5-nerved from at or near bases) mostly rhombic, deltate, ovate, or elliptic to lanceolate or lance-linear (sometimes intermediate shapes), sometimes pinnately or palmately lobed, bases cuneate to rounded or cordate, ultimate margins subentire or toothed, faces glabrous or hairy. Heads radiate or discoid, borne singly or in corymbiform, dichasiiform, or paniculiform arrays. Involucres hemispheric, turbinate, or campanulate to saucerlike, 5-20+[-30+] mm diam. Phyllaries persistent, 9-30[-50+] in 1-4[-5+] series (orbiculate, ovate, or oblong to spatulate, lanceolate, or linear, subequal or unequal, outer shorter or longer than inner, herbaceous to chartaceous). Receptacles flat to convex or ± conic, paleate (paleae usually navicular, ± conduplicate, herbaceous to scarious, linear to filiform in V. encelioides and V. nana). Ray florets 0 or (1-)5-30, either pistillate and fertile, or styliferous and sterile, or neuter; corollas yellow to orange or ochroleucous [reddish]. Disc florets 8-150[-300+], bisexual, fertile; corollas usually concolorous with rays, tubes much shorter than or ± equaling funnelform or campanulate throats, lobes 5, ± deltate to lance-deltate. Cypselae ± flattened, orbiculate, obovate, or oblanceolate to ± elliptic (usually winged); pappi persistent [falling], usually of 2, ± subulate scales or awns, sometimes 0. x = 17, 18?
