    Rubiaceae, B. Verdcourt. Flora Zambesiaca 5:1. 1989

    Habit
    Annual or perennial mostly erect herbs, occasionally subshrubs, more rarely dwarf shrubs, sometimes with short woody subterranean stems.
    Leaves
    Leaves sessile, opposite, mostly linear to narrowly elliptic-lanceolate, apex ± acute, midrib prominent below, rarely 3-nerved from the base; stipular sheath ± membranaceous, produced either into 1 or 2 ± fimbriated triangular lobes becoming narrower and often displaced towards leaves in apical parts or into 2–8 fringing ± subulate rigid fimbriae.
    Flowers
    Flowers hermaphrodite, 4-(rarely 3- or 5-) merous, medium to small, stigmas and anthers always included in the corolla tube, never heterostylous, in terminal thrysic, sometimes corymbose, extensive panicle-like, subcapitate or capitate inflorescences, occasionally rather few-flowered; subtending bracts at the base ± leaf-like reduced gradually to small triangular rudiments towards the top of the partial inflorescence branches.
    Calyx
    Calyx tube mostly ovoid, ovoid-elliptic to globose, occasionally hemispherical; calyx lobes 4 (5), small, (±) equal, narrowly triangular, subulate or ovate-lanceolate, sometimes keeled.
    Corolla
    Corolla tube narrowly cylindrical, with dilated barrel-shaped or more rarely narrowly funnel-shaped apical part; entrance to and throat inside glabrous or bearded with short flattened papillate hairs; corolla lobes broadly elliptic to narrowly linear, completely parted or shortly fused at the base, acute, sometimes mucronate or apiculate.
    Stamens
    Stamens contained within the upper dilated portion of the tube, completely included or only sterile anther connectives emergent; anthers ± sessile.
    Ovary
    Ovary bilocular with numerous ovules embedded in a fleshy peltate placenta attached by a short stalk to the middle of the septum.
    Pistil
    Style glabrous either bearing 2 filiform stigmatic lobes or a single fused cylindrical or ovoid stigma; stigma usually held well below the anthers or occasionally just touching anthers.
    Fruits
    Capsules hemispherical, globose, subglobose or ellipsoid, crowned by the permanent calyx lobes, splitting loculidally at the top, beak not conspicuous.
    Seeds
    Seeds numerous, roundish, angular or conical to subconical, light brown to blackish.

    Habit
    Annual or perennial herbs or rarely subshrubs, mostly erect, often much branched
    Leaves
    Leaves sessile, opposite, nearly always linear and mostly 1-nerved, less often penninerved or 3–5-nerved from the base; stipules with 2-several fimbriae or rarely reduced to a simple lobe
    Flowers
    Flowers small or medium-sized, never heterostylous, in panicles, corymbs, occasionally in heads, more rarely in pairs, triads or even solitary
    Calyx
    Calyx-lobes 4 (rarely 5), small, equal, subulate to ovate-triangular or triangular
    Corolla
    Corolla-tube narrowly cylindrical; lobes 4 (rarely 5); throat glabrous or pilose inside
    Stamens
    Stamens always included in the upper swollen part of the corolla-tube or only the anther-tips exserted
    Pistil
    Ovary 2-locular; ovules numerous, immersed in fleshy peltate placentas; style always included, the stigma not divided, cylindrical, or divided into 2 filiform lobes mostly with the tips well below the base of the anthers or just reaching them
