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

    Habit
    Trees or shrubs with branching similar to that of many Rothmannia species and characteristic evergreen foliage
    Leaves
    Leaves opposite, petiolate, thinly coriaceous, usually with ± transversely parallel venation; domatia absent or present and pubescent; stipules triangular, acute or acuminate, soon falling
    Inflorescences
    Inflorescences 1–several or occasionally ± many-flowered on very short terminal branchlets subtended by a single leaf but often lateral and pseudoaxillary owing to the sympodial growth of the stem; bracts small
    Calyx
    Calyx-tube ovoid to tubular; limb shortly cylindrical, with 5 triangular to lanceolate teeth
    Corolla
    Corolla ± pubescent to densely adpressed silky outside, narrowly campanulate; corolla-lobes 5, ovate to lanceolate
    Anthers
    Anthers linear, elongate, apiculate, sessile, usually medifixed, included or slightly to completely exserted; pollen grains simple
    Pistil
    Ovary 2-locular; each locule with a pendulous placenta carrying 2–10 embedded ovules; style filiform or elongate-clavate, glabrous or rarely pubescent, apical part sometimes 10-ribbed, and divisible into lobes up to 4–5 mm. long bearing the stigmatic surfaces; the whole style is divisible almost to the base if pulled gently
    Fruits
    Fruit fleshy, 1–several-seeded, subglobose, crowned by the persistent calyx-limb
    Seeds
    Seeds subglobose with abundant endosperm, apparently devoid of a testa; embryo with radicle superior.

    Habit
    Trees or shrubs with branching similar to that of many Rothmannia species and characteristic evergreen foliage.
    Leaves
    Leaves opposite, petiolate, thinly coriaceous, usually with ± transversely parallel venation; domatia absent or present and pubescent; stipules triangular, acute or acuminate, soon falling.
    Inflorescences
    Inflorescences 1–several-flowered or occasionally ± many-flowered on very short terminal branchlets subtended by a single leaf (TAB. 75/3&4), but can often appear lateral and/or pseudoaxillary owing to the sympodial growth of the stem; bracts small.
    Calyx
    Calyx tube ovoid to tubular; limb-tube shortly cylindrical, with 5 triangular to lanceolate teeth.
    Corolla
    Corolla ± pubescent to densely appressed silky outside, narrowly campanulate; corolla lobes 5, contorted to the left, ovate to lanceolate.
    Anthers
    Anthers linear, elongate, apiculate, sessile, usually medifixed, included or slightly to completely exserted; pollen grains simple.
    Pistil
    Ovary 2-locular; each locule with a pendulous placenta carrying 2–10 embedded ovules; style filiform or elongate-clavate, glabrous or rarely pubescent, apical part acting as a pollen presenter, sometimes 10-ribbed, and divisible into lobes up to 4–5 mm long bearing the stigmatic surfaces; the whole style is divisible almost to the base if pulled gently.
    Fruits
    Fruit fleshy, 1–several-seeded, subglobose, crowned by the persistent calyx limb.
    Seeds
    Seeds subglobose with abundant endosperm, apparently devoid of a testa; embryo with radicle superior.
    Distribution
    A monotypic genus restricted to tropical Africa, closely related to Aulacocalyx Hook.f.
