Annual to tree, vine. Leaf: generally opposite (whorled), entire; stipules generally fused to stem, adjacent pairs occasionally fused, or occasionally leaf-like and appearing like whorled leaves. Inflorescence: cyme, panicle, spike, cluster, or flower 1, generally terminal and ± axillary. Flower: generally bisexual; calyx ± 4(5)-lobed, occasionally 0 (Galium, Crucianella) or 6 (Sherardia); corolla generally radial, 4(5)-lobed; stamens epipetalous, alternate corolla lobes, generally included; ovary generally inferior, chambers generally 2 or 4, style 1(2). Fruit: drupe, berry, or 2 or 4 nutlets [capsule].
± 500 genera, 6000 species: worldwide, especially tropics; many cultivated, including Coffea, coffee; Cinchona, quinine; many ornamental. [Robbrecht & Manen 2006 Syst & Geogr Plant 76:85–146] Diodia teres Walter doubtfully in California. —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
