Leaves simple to pinnately compound, basal or cauline, alternate or opposite; stipules 0
Inflorescence: cyme (generally raceme-like and coiled) or flowers solitary
Flower bisexual, generally radial; calyx lobes generally 5, generally fused at base, generally persistent, enlarging in fruit; corolla generally deciduous, rotate to cylindric, lobes generally 5, appendages in pairs on tube between filaments or 0; stamens generally 5, epipetalous, filament base sometimes appendaged, appendages scale-like; ovary generally superior, chamber 1, placentas 2, parietal, enlarged into chamber, sometimes meeting so ovary appears 2–5-chambered, styles 1–2, stigmas generally head-like

Stem erect, much-branched
Leaves simple, 1–3-pinnately toothed to dissected; lower cauline leaves opposite, petioled; upper leaves alternate, becoming smaller, sessile, clasping; petioles generally narrowly winged, ciliate
Inflorescence terminal or axillary; pedicels thread-like, elongate in fruit
Flower: calyx < half-fused, bell-shaped, glandular, lobes oblong to spoon-shaped, ciliate; corolla bell-shaped, generally > calyx, with V-shaped transverse fold between each pair of filaments below throat; stamens included, equal, equally attached; ovary chamber 1 (or appearing 5 from complex, enlarged placenta), ovules borne on both sides of placenta, style 1, stigmas 2
Fruit ovoid to spheric, bristly
Seeds 5–15
