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

Habit
Shrubs or small trees, occasionally suffrutices
Leaves
Leaves opposite, occasionally ternate, sessile or petiolate; blades with bacterial nodules usually present and domatia sometimes present in the axils of the nerves beneath; stipules, with a triangular to truncate limb, connate at base or up to the entire length, bearing a subulate arista or less often a short mucro, sometimes with silky hairs within
Flowers
Flowers (1–)few–many, borne in sessile to subsessile corymbs, terminal on main and lateral leafy branches or terminal on short leafless spurs or branches (which in the absence of corky bark can resemble axillary pedunculate corymbs), occasionally entirely suppressed giving the inflorescence an axillary appearance, very lax to capitate; bracts connate, stipule-like; bracteoles free, usually small, sometimes absent Flowers hermaphrodite, always 4-merous
Calyx
Calyx-tube turbinate to campanulate; limb persistent or deciduous, rarely accrescent; tube very short or long, often wider than the tube; lobes short to long, ovate (often overlapping) to triangular, lanceolate to subulate, occasionally absent
Corolla
Corolla white to creamy or greenish white, rarely red (P. canescens DC. from Angola and Zaire); tube cylindrical to funnel-shaped (but never greatly widened at the throat), throat bearded or pubescent to glabrous; lobes lanceolate, oblong or ovate, contorted in bud
Stamens
Stamens attached at the mouth of the tube, exserted and spreading or reflexed in mature flower; filaments very short; anthers dorsifixed near the base, linear to oblong, ± equalling the corolla-lobes in length, apiculate and sagittate, usually twisted when dehisced
Disc
Disc annular, fleshy
Pistil
Ovary small, 2-locular (? very rarely 4-locular); placentas fleshy, pendulous from the apex of the septum; ovules solitary or rarely paired, immersed or partially immersed in the cup-like placenta; style long-exserted, slender, glabrous to subglabrous, sometimes the exserted portion pubescent, the upper part (pollen receptacle) thickened, club-shaped, with 8 shallow ribs, always shortly hairy; stigmatic surface confined to the bidentate apex
Fruits
Fruit a drupe, frequently black and shining, rarely white or coloured, spherical, slightly 2-lobed, scarcely fleshy, containing 1(–2) chartaceous pyrenes
Seeds
Seeds 2 (or rarely 1 by abortion), attached to the centre of the septum, hemispherical with a wide circular excavation in the centre of the ventral face, convex dorsal face usually rugose; endosperm always entire and horny; embryo small, dorsal, curved.

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

Habit
Shrubs or small trees, occasionally subshrubs with woody underground stems.
Leaves
Leaves opposite, occasionally ternate, sessile or petiolate, sometimes those on inflorescence-supporting branches differ from those on the main stem or vegetative shoots, being smaller with shorter petioles or anisophyllous, sometimes shape may differ according to position of the branches (see note after P. gardeniifolia); blades sometimes with domatia present in the nerve axils beneath and usually with blackish dot-like elliptic or linear bacterial nodules scattered on the blade or arranged along the midrib; stipules with a triangular to truncate limb, connate at the base or for up to the entire length, bearing a subulate arista, less often a short mucro or a keeled lobe, sometimes with silky hairs within.
Inflorescences
Inflorescences sessile or subsessile with (1)few–many flowers in a very lax to capitate corymbose arrangement, terminal on main and lateral leafy branches or on short leafless spurs or branches (which in the absence of corky bark can resemble axillary pedunculate corymbs), occasionally such inflorescence-supporting branches entirely suppressed giving the inflorescence an axillary appearance (TAB. 108); bracts connate, stipule-like; bracteoles free, usually small, sometimes absent.
Flowers
Flowers hermaphrodite, always 4-merous.
Calyx
Calyx tube turbinate to campanulate; limb persistent or deciduous, rarely accrescent; limb-tube very short or long, often wider than the tube; lobes short to long, ovate (often overlapping) to triangular, lanceolate to subulate, often separated by sinuses or occasionally absent (TAB. 109).
Corolla
Corolla white to cream-coloured or greenish-white, infrequently yellow or rarely red (P. canescens DC. from Angola and Dem. Rep. Congo); tube cylindrical to funnel-shaped (but never greatly widened at the throat), bearded or pubescent to glabrous in the throat; lobes lanceolate, oblong or ovate, contorted in bud.
Stamens
Stamens attached at the mouth of the tube, exserted and spreading or reflexed in mature flower; filaments very short; anthers dorsifixed near the base, linear to oblong, ± equalling the corolla lobes in length, apiculate and sagittate, very often twisted when dehisced.
Disc
Disk annular, fleshy.
Pistil
Ovary small, 2-locular (?very rarely 4-locular); placentas fleshy, pendulous from the upper part of the septum; ovules solitary or rarely paired, immersed or partially immersed in the cup-like arrangement of tissues; style long-exserted, slender, glabrous to subglabrous, sometimes the exserted portion pubescent, the upper part (pollen presenter) thickened, club-shaped, with 8 shallow ribs, always shortly hairy; stigmatic surface confined to the bidentate apex.
Fruits
Fruit a drupe, frequently black and shiny, rarely white or coloured, spherical, slightly 2-lobed, scarcely fleshy, containing 1(2) chartaceous pyrenes.
Seeds
Seeds 2 (or rarely 1 by abortion), attached to the centre of the septum, hemispherical with a wide circular excavation in the centre of the ventral face, convex dorsal face usually rugulose; endosperm always entire and horny; embryo small, dorsal, curved.
