    Apocynaceae, A. J. M. Leeuwenberg & F. K. Kupicha et al. Flora Zambesiaca 7:2. 1985

    Habit
    Rhizomatous creepers, climbing shrubs or lianas with white latex.
    Spines
    Spines, tendrils and stipules absent.
    Leaves
    Leaves petiolate; petiole with glands on the adaxial side; lamina with the midrib impressed above and prominent beneath; secondary veins curved towards the margin, anastomosing; tufts of hairs (domatia) usually present in the axils of some secondary veins.
    Inflorescences
    Inflorescences axillary and sometimes at the same time terminal.
    Calyx
    Calyx lobes imbricate, almost free, at the base often with colleters inside.
    Corolla
    Corolla tube obconical, with a short urceolate base; inside with tufts of hairs alternating with the stamens; corolla lobes contorted in bud and overlapping to the right, spreading to reflexed.
    Stamens
    Stamens inserted almost at base of the corolla tube; anthers conivent in a cone around the gynoecium, adaxially pubescent, fertile in the upper part only, sagittate at the base, acuminate at the apex, coherent with the clavuncula by a retinacle (a circular patch between the tails inside on the connective 0·1–0·2 mm. in diam).
    Pistil
    Ovary semi-inferior; carpels two, multi-ovulate, connate at the extreme base only, abruptly narrowed into the style, surrounded by a disk; disk adnate to the ovary at the base only, ring-shaped, with 5 oblong lobes alternating with the stamens; style obconical to almost cylindrical; clavuncula consisting of a slightly 5-winged upper and a cylindrical lower portion, to the latter of which the 5 retinacles adhere; stigma bilobed.
    Fruits
    Fruit composed of 2 pendulous, follicular, narrowly cylindrical mericarps, these sometimes united at the apices.
    Seeds
    Seeds narrowly ellipsoid, more or less laterally compressed, not rostrate, with an apical coma; endosperm in a thin layer completely surrounding the embryo.

    Habit
    Climbing shrubs, lianas or rhizomatous creepers (not in our area) with white latex; tendrils, axillary glands and stipules absent
    Leaves
    Leaves opposite, petiolate; petiole with colleters above, near base to halfway up; domatia usually in some vein axils
    Inflorescences
    Inflorescences axillary and terminal, few to many-flowered cymes
    Flowers
    Flowers 5-merous, fragrant or not; sepals imbricate, with 0–10 colleters at the base inside
    Corolla
    Corolla tube with dense tufts of hairs alternating with the stamens inside, usually with scales or ridges above the insertion of the stamens; lobes contorted in bud, overlapping to the right
    Stamens
    Stamens inserted in lower part of corolla tube; anthers connivent into a cone over the pistil head, coherent with the pistil head by a circular patch, the retinacle
    Ovary
    Ovary semi-inferior, carpels two, connate at the extreme base, disk present, adnate to the ovary base; pistil head with a nearly cylindrical basal part, adhering to the anthers, a slightly 5-winged central part and a bilobed stigmoid apex
    Fruits
    Fruits of 2 pendulous, follicular mericarps, connate at the extreme base and sometimes at the apex, usually slightly constricted between the seeds; seeds with a deciduous apical coma directed towards the apex of the mericarp.
