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.

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
