Flower: bisexual; calyx generally 4–5-toothed; corolla 4–5-lobed, radial to bilateral, salverform to 2-lipped; stamens 4–5 (if 4, generally in unequal pairs), epipetalous; ovary superior, 2- or 4-lobed, generally 2- chambered, style 1, often with 2 unequal lobes, only 1 stigmatic, lateral. Fruit: 2 or 4 nutlets, drupe-like, or capsule.
