    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 (TAB. 75/3&4) but often lateral and pseudoaxillary owing to the sympodial growth of the stem; bracts small.
    Calyx
    Calyx tube ovoid to cylindrical; limb-tube shortly cylindrical with 5 triangular to lanceolate teeth.
    Corolla
    Corolla pubescent to densely appressed silky outside, salver-shaped with narrow cylindrical tube but in some species (formerly referred to Dorothea) the corolla tube is split unilaterally giving the corolla an irregular appearance; 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
    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 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 baccate, 1–several-seeded, subglobose, crowned by the persistent calyx limb.
    Seeds
    Seeds subglobose with abundant endosperm, devoid of a testa.
