CAMPANULACEAE

BELLFLOWER FAMILY

Nancy Morin, except as specified

Annual to tree
Leaves generally cauline, generally simple, generally alternate, petioled or not; stipules 0
Inflorescence: panicle, raceme, spike, or flowers solitary in axils, generally open; bracts leaf-like or not
Flower: bisexual, radial or bilateral, sometimes inverted (pedicel twisted 180°; hypanthium generally present, ± fused to ovary; sepals generally 5; corolla radial to 2-lipped, generally fused (tube sometimes split down back), lobes generally 5; stamens 5, free or ± fused (anthers and filaments fused into tube or filaments fused above middle); ovary inferior, sometimes half inferior, chambers 1–3, placentas axile or parietal, ovules many, style generally 1, 2–5-branched
Fruit: generally capsule, dehiscing on sides or at tip by pores or short valves
Seeds many
Genera in family: ± 70 genera, ± 2000 species: worldwide. Some cultivated for ornamental (Campanula, Jasione, Lobelia ). Subfamilies sometimes treated as different families.
