Inflorescence: cyme, panicle, cluster, or flower solitary, generally terminal and ± axillary
Flower generally bisexual; calyx generally ± 4-lobed, sometimes 0; corolla generally radial, 4-lobed; stamens epipetalous, alternate corolla lobes, generally included; ovary generally inferior, chambers generally 2 or 4, style 1, ± fused if 2
Fruit: 2 or 4 nutlets or a berry, drupe, or capsule
Genera in family: ± 500 genera, 6000 species: worldwide, especially tropical; many cultivated (including Coffea , coffee; Cinchona , quinine; many ornamental)

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).
