CAMPANULACEAE BELLFLOWER FAMILY

Nancy R. Morin, except as noted


Annual to perennial herb [tree]. Leaf: generally cauline, generally simple, generally alternate, petioled or not; stipules 0. Inflorescence: cyme, panicle, raceme, spike, or flowers 1; terminal or in axils of leaf-like or reduced bracts. Flower: bisexual, cleistogamous or open, radial or bilateral, inverted (pedicel twisted 180°) or not; hypanthium generally present, ± fused to ovary; sepals generally 5; corolla radial to 2-lipped, petals generally fused, tube deeply divided on 1 side or not, lobes generally 5; stamens 5, free or ± fused (anthers, filaments fused into tube or filaments fused above middle); ovary inferior or 1/2 inferior (superior in fruit), chambers 1–3, placentas axile or parietal, ovules many, style generally 1, 2–5-branched. Fruit: generally capsule, open on sides or top by pores or short valves. Seed: many.
± 90 genera, ± 2500 species: worldwide. [Haberle et al. 2008 J Molec Evol 66:350–361] Some cultivated for ornamental (Campanula, Jasione, Lobelia). Subfamilies sometimes treated as families. Positions of flower parts given after flowering inversion, if any. Parishella moved to Nemacladus. —Scientific Editor: Thomas J. Rosatti.
