Leaves alternate, petiolate or subsessile; lamina highly variable in size and shape; narrow-ovate to narrow-obovate, 8–114 mm long, 3–23 mm wide; margins entire to deeply lobed, upper surface grey or green, glabrous to moderately stellate-hairy, sometimes with sessile glands; lower surface white to grey or yellow, with dense, minute, stellate hairs of equal size, usually with some sessile glands; venation finely reticulate, shallowly impressed, secondary veins often not visible on the lower lamina.
Flowerheads in terminal or subterminal paniculate or corymbose conflorescences, or solitary and terminal; pedunculate; involucre campanulate to hemispherical, 3–7 mm long, 5–12 mm in diameter; bracts 4- or 5-seriate, graduating, pubescent, sometimes with glands, margins and tips sometimes purple. Ray florets 6–22, white, rarely mauve, ligules 5–12 mm long; disc florets 6–25, yellow, tips of corolla lobes variously pubescent or glabrous.
