    [FTEA]

    Apocynaceae (part 2), David Goyder, Timothy Harris, Siro Masinde, Ulrich Meve, Johan Venter. Flora of Tropical East Africa, 2012

    Habit
    Mesophytic climbers or sclerophyllous shrubs, scramblers or small trees with white or occasionally yellow or orange latex; interpetiolar ridges and leaf axils with reddish dentate colleters
    Leaves
    Leaves opposite on normal shoots, sub-fascicled on stunted shoots, petiolate to sessile; blade herbaceous, leathery or succulent
    Inflorescences
    Inflorescences few to many-flowered or flowers solitary
    Flowers
    Flower buds with corolla apex helically twisted and deltoid to apiculate
    Corolla
    Corolla tube campanulate and shorter than lobes, rarely cylindrical and longer than lobes, mostly with elliptic papillose spot below every corona lobe; lobes linear to ovate
    Corona
    Corolline corona 1- or 2-whorled; lower whorl of lobes inserted around middle of corolla tube, mostly concealed; lobes clavate, acicular, peg-like or filiform, glabrous, free; upper whorl, when present, of simple pockets or lobed pockets in corolla lobe sinuses Gynostegial corona absent
    Stamens
    Stamens inserted near base of corolla tube.
    Filaments
    Filaments short, mostly dilated.
    Anthers
    Anthers deltoid to hastate, glabrous or rarely hairy; pollen in tetrads
    Nectaries
    Insterstaminal nectifery pouches at base of corolla tube
    Style
    Style-head deltoid, broadly deltoid, ovoid or broadly ovoid, translators with receptacle concavely narrowly elliptic and sessile on sticky disc.
    Gynostegium
    Gynostegium concealed at bottom of corolla tube
    Fruits
    Follicles paired, widely to narrowly divergent, cylindrical-ovoid to narrowly ovoid.

    Apocynaceae (part 2), David Goyder, Timothy Harris, Siro Masinde, Ulrich Meve, Johan Venter. Flora of Tropical East Africa, 2012

    Habit
    Lianas with white latex.
    Stem
    Stems woody, twining
    Leaves
    Leaves glabrous, petiolate, leathery
    Inflorescences
    Inflorescences axillary, many-flowered, glabrous
    Calyx
    Sepals glabrous, with colleters at their inner bases.
    Corolla
    Corolla coriaceous, deep crimson, purplish or pink
    Corona
    Corolline corona near base of corolla tube or on inversion of corolla tube, coronal feet fused to stamens and nectaries forming a collar Gynostegial corona absent
    Stamens
    Stamens arising from inner base of coronal feet; pollen in tetrads
    Style
    Style terete; style-head deltoid, obtuse; translator with receptacle, stalk and sticky disc
    Fruits
    Follicles paired, horizontally opposite
    Note
    Young stems, leaves, peduncles and flowers of both species turn black when drying. The flowers are so different in morphology that the two species were separated in different genera (Venter & Verhoeven in S. Afr. Journ. Bot. 62: 23–30 (1996)), but DNA-analysis proves them to be sister species (Ionta & Judd in Ann. Missouri Bot. Gard. 94: 372 (2007)).
