Note
In the narrow sense used by Hallé & Mathew in Fl. Trop. E. Afr. (1994), Hippocratea does not occur in Somalia and the two species included here belong to Loeseneriella (H. crenata) and Pristimera (H. andongensis).

Morphology General Habit
Lianes or ± scandent shrubs or small trees, without latex (except in sect. Hippocratea).
Morphology Leaves
Leaves opposite or subopposite, petiolate; stipules free or ± united interpetiolarly, usually deciduous, with opposite pairs sometimes connected by ridges.
Morphology Reproductive morphology Inflorescences
Inflorescence pedunculate, cymose, dichasial or submonochasial, simple or compound, with or without accessory branches, axillary; bracts persistent.
Morphology Reproductive morphology Flowers
Flowers bisexual.
Morphology Reproductive morphology Flowers Calyx
Sepals (4) 5, imbricate, free or ± united.
Morphology Reproductive morphology Flowers Corolla
Petals (4)5(6), green to white or yellow, often with paler margin, imbricate or valvate in bud.
Morphology Reproductive morphology Flowers Disc
Disk extrastaminal, single or double, varying in shape, free or variously united with other floral parts.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens (2)3(4), with filaments often ± broadened below, free or united at the base or sometimes united with the ovary or gynophore; anthers versatile, apical or extrorse, with the thecae ± confluent, dehiscing transversely; pollen simple or rarely in polyads (sect. Hippocratea), not in tetrads.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary superior, 3-locular, with 2–20 axile ovules in 2 rows per loculus, sessile or on a gynophore, sometimes immersed in the disk; style simple or absent; stigmas 3, free or ± united, sometimes sessile or very small.
Morphology Reproductive morphology Fruits
Fruit of 3 capsular mericarps united at the base or rarely (not in African species) for most of their length; mericarps dorsiventrally flattened or rarely biconvex, dehiscing by the median suture.
Morphology Reproductive morphology Seeds
Seeds with long stalks, rarely sessile; stalks usually expanded into a wing with the raphe forming a submedian or rarely marginal vein and the thickened integuments forming a vein along the other margin. Germination epigeal or hypogeal.
Cytology
Chromosome number: 2n=56 (3 species).
