Leaves cauline and basal or all basal and forming a rosette; rosette leaves persistent in winter or dying away to a resting bud or buds; blade entire, serrate, or pinnatifid to pinnate, glabrous to bristly; basal leaves and lower cauline leaves usually petiolate; upper cauline leaves shortly petiolate or sessile, sometimes amplexicaul. Inflorescence a raceme, panicle, or pseudoumbel, with uppermost flower opening first, or flowers solitary, then often on basal scapes. Flowers large, often bowl- or saucer-shaped. Sepals 2, very rarely 3 or 4 in terminal flowers, caducous. Petals 4-10, occasionally more, blue, purple, pink, red, or yellow, rarely white. Stamens numerous; filaments mostly linear, rarely dilated in lower part. Ovary nearly spherical, ovoid, or obovoid to narrowly terete, 1-loculed, with 3 or more carpels, containing numerous ovules; styles distinct, usually short, sometimes almost absent, regularly stout or basally expanding into a disk covering top of ovary; stigmas free or united, capitate or clavate. Capsule nearly spherical, ovoid, obovoid, or elliptic to cylindrical, spiny, setose, pubescent, or glabrous, 3-12(-18)-valvate; segments slightly lobed or divided to 1/3 length or more from apex to base.
