Rhamnaceae, Marshall C. Johnston (University of Texas Herbarium). Flora of Tropical East Africa. 1972

Morphology General Habit
Climbing shrubs or lianes with circinnate tendrils (rarely, or apparently never in Africa, seeming to be mere shrubs)
Morphology Leaves
Leaves alternate, petiolate; blades usually ovate, serrate (rarely nearly entire), acute or acuminate, at base usually rounded or cordate and often 3–5-nerved but penninerved more distally
Morphology Leaves Stipules
Stipules present, free, usually caducous
Morphology Reproductive morphology Inflorescences
Cymes usually small, but usually aggregated into ample leafless terminal panicles
Morphology Reproductive morphology Flowers
Flowers 5-merous, bisexual, epigynous at all stages
Morphology Reproductive morphology Flowers Disc
Disk rather massive, epigynous
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary usually urceolate; style trifid or obscurely 3-lobed
Morphology Reproductive morphology Fruits
Fruit a dry schizocarpous capsule, late in maturation the endo- and exocarpous tissue near the septa (on both sides of each mericarp) producing 3 broad thin wings (thus each wing is composed of parts of 2 adjacent mericarps; reportedly the wing-production fails in certain Asian and American, but not African, populations, and perhaps the reports are based on observations of immature fruit, for the wing-proliferation is a quite late development).
