Herbs annual or perennial, rarely subshrubs or vines. Leaves alternate or opposite, sessile to petiolate, simple, pinnatifid to palmately lobed, or compound. Inflorescences determinate, corymbose, paniculate, or capitate, or flowers solitary. Flowers (4- or)5-merous. Calyx gamosepalous, cylindric to campanulate; tube herbaceous throughout and papery in fruit or with herbaceous midveins separated by translucent membranes distended or ruptured in fruit; lobes often scarious margined. Corolla gamopetalous, actinomorphic or zygomorphic, rotate to funnelform or salverform; lobes overlapping in bud. Stamens inserted at same or different levels on corolla at base, alternate with corolla lobes, exserted to included; filaments equal to unequal, filiform. Ovary superior, (2- or)3-locular, placentation axile; ovules 1 to many per locule. Style 1; stigma lobes (2 or)3. Fruit a capsule. Seeds globose, ovoid, or fusiform, sometimes winged, often sticky when wet. Fls perfect, hypogynous, sympetalous, mostly (incl. all ours) 5-merous; cal usually gamosepalous, with equal or unequal lobes, the tube often with alternating green ribs and hyaline intervals (between the lobes); cor regular in most genera (incl. all ours), its lobes convolute in bud; stamens as many as and alternate with the cor-lobes, borne on the tube, sometimes at differing levels; ovary superior, mostly tricarpellate and trilocular, with a terminal style and usually 3 separate stigmas; ovules 1– many in each locule, on axile placentas; fr usually a loculicidal capsule; embryo straight or slightly curved, usually spatulate, with 2 cotyledons; endosperm usually oily, seldom scanty or none; mostly (incl. all ours) herbaceous or merely suffrutescent; lvs exstipulate. 18/300, best developed in w.
