Morphology General Habit: Shrubs or trees, repeatedly dichotomously branched and with 2 inflorescences in the forks when flowering (rarely one of the inflorescences not developing).
Morphology Stem: Bark with abundant white latex. Branchlets terete or elliptic on section in African species, often sulcate and angular when dried.
Morphology Leaves: Leaves opposite, those of a pair equal or unequal, petiolate (at least in species of the F.Z. area); petioles of a pair connate into a conspicuous ocrea, with colleters in the axils; lamina broadly to narrowly elliptic.
Morphology Reproductive morphology Inflorescences: Inflorescence distinctly pedunculate, corymbose, lax to congested.
Morphology Reproductive morphology Inflorescences Bracts: Bracts deciduous, but at least in species of the F.Z. area still present at anthesis.
Morphology Reproductive morphology Flowers: Flowers actinomorphic, except for the subequal sepals, fragrant.
Morphology Reproductive morphology Flowers Calyx: Sepals green or of different colour, almost free.
Morphology Reproductive morphology Flowers Corolla: Corolla white, pale yellow or mauve (Madagascan spp.), with an often green or greenish tube and a pale yellow throat, thick and carnose or thin; tube twisted, in species of the F.Z. area at least twice as long as the calyx; lobes in bud overlapping to the left and folded inwards, twisted, usually obliquely elliptic, usually curved to the right, spreading and often recurved later.
Morphology Reproductive morphology Flowers Androecium Stamens: Stamens included or less often exserted; filaments reduced to ridges or nearly so; anthers narrowly triangular, acuminate at the sterile apex, sagittate at the base, introrse, dehiscent throughout by a longitudinal slit.
Morphology Reproductive morphology Flowers Gynoecium Pistil: Ovary composed of two carpels, these barely to distinctly connate at the base and connected at the apex by the style; style often split at the base; disk absent (at least in species of the F.Z. area); clavuncula not coherent with the anthers and therefore the pistil still complete immediately after the corolla is shed.
Morphology Reproductive morphology Fruits: Fruit of two free or basally united subglobose, subellipsoid or pod-like carnose carpels (sometimes one remaining smaller or not developing); carpels opening along an adaxial line of dehiscence or not.
Morphology Reproductive morphology Seeds: Seeds several or many, enveloped by a thin variously coloured pulpy aril, nearly obliquely ellipsoid, with a deep groove to halfway its width at the hilar side; endosperm ruminate.

Morphology General Habit: Shrubs or trees repeatedly dichotomously branched
Morphology General Exudate: Latex present in most parts
Morphology General Bark: Bark smooth or rough, usually with large lenticels
Morphology Branches: Branches with large lenticels and conspicuous leaf scars; branchlets terete, glabrous
Morphology Leaves: Leaves opposite; petiole glabrous, those of a pair usually connate into a conspicuous ochrea, these frequently widened into intrapetolar stipules, with colleters in axils; blade glabrous on both sides (occasionally pubescent beneath in T. elegans), entire.
Morphology Reproductive morphology Inflorescences: Inflorescence terminal or in forks, corymbose
Morphology Reproductive morphology Inflorescences Bracts: Bracts deciduous, with colleters in axils, leaving large scars
Morphology Reproductive morphology Flowers: Flowers 5-merous, actinomorphic, sweet-scented
Morphology Reproductive morphology Flowers Calyx: Sepals imbricate in bud
Morphology Reproductive morphology Flowers Corolla: Corolla tube thin or thick and fleshy, twisted or not; lobes overlapping to the left, twisted, folded inwards, obliquely ellipsoid and falcate, curved to the right, often auriculate at the left side at the base
Morphology Reproductive morphology Flowers Androecium Stamens: Stamens included; filaments short or reduced to ridges; anthers sessile, narrowly triangular, acuminate at the sterile apex, sagittate at the base, with connectives adnate to the corolla
Morphology Reproductive morphology Flowers Gynoecium Pistil: Ovary superior, of two carpels, barely to distinctly connate at the base, connate at the apex by the style; pistil head not coherent with anthers, subglobose or cylindrical with 5 suborbicular or elliptic lobes at the apex and an entire undulate or lobed ring at the base
Morphology Reproductive morphology Fruits: Fruit of two separate or rarely basally united mericarps, subglobose to pod-like, baccate, dehiscent or not; aril pulpy, white, orange or red
Morphology Reproductive morphology Seeds: Seeds brown or black, with a deep groove on the hilar sides; endosperm copious, starchy, white, ruminate; embryo spatulate
