Higher Taxonomy
Family: RubiaceaeView DescriptionDichotomous Key

Habit: 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].
Genera In Family: +- 500 genera, 6000 species: worldwide, especially tropics; many cultivated, including Coffea, coffee; Cinchona, quinine; many ornamental. Note: Diodia teres Walter doubtfully in California.

Leaf: generally in whorls of >= 4, including leaf-like stipules. Inflorescence: panicles, axillary clusters (cymes), or occasionally 1 in axils. Flower: bisexual, or unisexual with sterile stamens or pistils; calyx 0; corolla generally rotate, occasionally +- bell-shaped, generally +- green, yellow to white, occasionally pink or red, lobes generally 4; ovary 2-lobed, styles 2, bases +- fused.
