Rubiaceae, B. Verdcourt. Flora of Tropical East Africa. 1976

Habit
Shrubs, small trees or occasionally small pyrophytic subshrubs, unarmed or lateral branches becoming stoutly spinescent; young parts often glutinous; branches sometimes in whorls of 3
Leaves
Leaves opposite or verticillate, petiolate, thin to distinctly coriaceous, with or without domatia; stipules sheathing, often truncate; buds containing wax-secreting glands

Calyx
Calyx-tube variously shaped with the tubular part of the limb usually well-developed, truncate or with marginal or submarginal often decurrent lobes; limb sometimes unilaterally split
Corolla
Corolla-tube funnel-shaped or cylindrical and then usually long and narrow; lobes 5–12, contorted, overlapping to the left in bud, obtuse or rounded at the apex
Anthers
Anthers included or apices just exserted; pollen grains in tetrads
Pistil

Anthers
Anthers included, apices just exserted or up to ½ exserted.
Pollen
Pollen grains in tetrads.
Pistil
Ovary 1-locular at least in the basal part, or 2-locular in G. brachythamnus with 2–9 parietal placentas; style elongate, glabrous or pubescent; pollen presenter clavate, bilobed or not, usually many-lamellate, ± exserted.
Fruits
Fruit globose or ellipsoid with a usually thick fibrous or woody wall.
