    Rubiaceae, D.M.Bridson & B.Verdcourt. Flora Zambesiaca 5:3. 2003

    Habit
    Scandent shrubs or lianes, often with hairy stems.
    Leaves
    Leaves petiolate; domatia absent or present as hairy tufts in the axils of the lateral and sometimes the tertiary nerves beneath (referred to in text below as domatial hairy tufts); bacterial nodules absent; stipules with 3–15 fimbriae or with a single lobe.
    Flowers
    Flowers hermaphrodite, 4–5(6)-merous, sessile or pedicellate in pyramidal to racemiform or hemispherical to flat-topped panicles, terminal on the main or short lateral branches, sessile to pedunculate (the presence of rudimentary leaves frequently renders this character ambiguous); bracts and bracteoles present, the latter either conspicuous and exceeding the calyx or inconspicuous.
    Calyx
    Calyx tube ovoid to campanulate; limb-tube usually short, slightly wider than the tube, bearing 4–5(6) ovate, subulate, filiform to linear or triangular lobes.
    Corolla
    Corolla white or cream-coloured, usually small, salver-shaped; tube cylindrical to funnel-shaped, glabrous to sparsely pubescent inside; lobes 4–5(6), contorted to the right in bud, spreading or reflexed.
    Stamens
    Stamens attached at the mouth of the tube, exserted, or at least partly so; filaments short; anthers attached near the base or occasionally near the middle, usually shortly apiculate.
    Disc
    Disk fleshy, glabrous.
    Pistil
    Ovary 2(3)-locular (or incompletely so); ovules solitary, inserted on a small fleshy placenta ascending from the base of the ovary; style slender, greatly or less often scarcely exceeding the corolla tube, glabrous or nearly so or less often densely pubescent just above the base; pollen presenter exserted or occasionally not fully exserted, fusiform, clavate or broadly elliptic to globose, entire (or rarely 2–3-lobed).
    Fruits
    Fruit frequently orange to red, drupaceous, spherical, somewhat fleshy with a chartaceous endocarp, 1-locular, calyx limb persistent or less often deciduous.
    Seeds
    Seed 1 per fruit, globose, filling the locule, hilum basal, irregular; testa thin, reticulate, albumen horny, deeply ruminate; embryo curved.
