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

    Habit
    Mostly spiny many-stemmed shrubs or small trees, occasionally small pyrophytic subshrubs.
    Spines
    Spines straight, those on young or coppice shoots opposite and decussate, borne above leaf nodes (TAB. 127/1), those on older stems borne above cushion shoots and/or brachyblasts, paired, solitary (alternate or not) or absent (from specimen if not from plant) (TAB. 127/2 &3), often developing into fertile branches (long internode at base) (TAB. 127/4).
    Stem
    Brachyblasts (short axillary densely crowded branchlets) frequently developing into simple or branched fertile branches (nodes crowded at base) (TAB. 127/5).
    Leaves
    Leaves deciduous, paired and well spaced on young or coppice shoots, or clustered on cushion shoots and/or brachyblasts, glabrous to tomentose, petiolate; stipules, triangular, apiculate.
    Flowers
    Flowers sweet-scented, (4)5-merous, rather small, hermaphrodite or functionally male and female (whether plants are functionally male or female or whether different expressions at different times is not known).
    Inflorescences
    Inflorescences terminal or subterminal, few-branched, on cushion shoots and brachyblasts, functionally female/hermaphrodite flowers solitary or 2–3; functionally male/hermaphrodite flowers 1–8(or more); peduncles present or reduced; pedicels short or well developed, often accrescent; bracts and bractlets absent, rudimentary or filiform.
    Calyx
    Calyx tube ovoid or campanulate; limb-tube shortly cylindrical or sometimes urceolate; lobes rapidly developing as flower buds open, separated by narrow or wide sinuses often with a rudimentary lobe in each, often differing between male and female flowers, in male and/or hermaphrodite flowers variable in number and unequal, mostly oblong, ovate or spathulate or sometimes virtually reduced, or in female and/or hermaphrodite flowers (4)5 subequal or equal, ovate, broadly ovate or circular, sometimes clawed at base.
    Corolla
    Corolla subrotate, the tube shorter than the lobes and mostly subequal to or shortly exceeding (not in the Flora Zambesiaca area) the calyx limb-tube; tube glabrous at base, densely silky pubescent above outside, with a distinct band of long hairs inside; lobes contorted to the left in bud, usually broadly ovate to circular and spreading, pubescent outside, inside with puberulous margin.
    Stamens
    Filaments short; anthers exserted, oblong, apiculate; pollen grains single.
    Pistil
    Ovary 2(3)-locular, the placenta attached to the septum; ovules numerous embedded in placental mass; style as long as tube or exserted; pollen presenter ellipsoid or cylindrical, grooved.
    Fruits
    Fruit with seed masses divided by the septum; crowned by persistent and sometimes accrescent calyx limb.
    Seeds
    Seeds embedded in a pulpy matrix, discoid or compressed ellipsoid, with slightly raised fine reticulation on testa.

    Habit
    Mostly spiny shrubs or small trees, occasionally small pyrophytic subshrubs, the spines opposite or solitary and alternate
    Leaves
    Leaves mostly clustered on short opposite axillary branchlets or cushion-like shoots; stipules interpetiolar, ovate-acuminate to triangular, apiculate, deciduous
    Flowers
    Flowers 5-merous, rather small, 1–6 or more in terminal (sometimes appearing lateral) simple or branched cymes, each component ± 3-flowered, or 1–2(–3)-fasciculate or at least peduncle almost obsolete in species with very reduced cushion-shoots; bracts on the rachis absent or filiform; pedicels well developed
    Calyx
    Calyx-tube ovoid or campanulate; limb-tube shortly cylindrical, ellipsoid or urceolate, the lobes short, mostly oblong, ovate or long and spathulate
    Corolla
    Corolla subrotate, the tube shorter than the lobes, densely pubescent outside save for the base of the tube; tube with a distinct band of long hairs inside
    Anthers
    Anthers exserted, oblong, apiculate; pollen grains single
    Pistil
    Ovary 2(–3)-locular, the placentae attached to the septum; ovules numerous; style as long as tube or exserted; stigma ellipsoid or cylindrical, grooved or with 2 diverging transversely elliptic flattened lobes
    Fruits
    Fruit with seed masses divided by the septum
    Seeds
    Seeds discoid or compressed-ellipsoid with slightly raised reticulation on testa, embedded in a pulpy matrix.
