    Habit
    A weak-stemmed perennial herb, often woody below, variable in habit from lax and prostrate, supported by other plants or scrambling to 4 m. (or probably more).
    Stem
    Stem and branches glabrous or thinly to rather densely furnished with brownish multicellular hairs.
    Leaves
    Leaves lanceolate-ovate to broadly or deltoid-ovate, acuminate, glabrous or with multicellular hairs below (especially along the nerves), or rarely also the superior surface; larger leaves 3.5–10 × 2.5–5 cm., shortly cuneate to truncate or subcordate at the base, attenuate along a slender petiole; superior and branch leaves smaller, often narrower and more attenuate at the base.
    Inflorescences
    Inflorescences white, axillary and terminal, densely or more rarely laxly thyrsoid, the upper usually more or less congested to become spiciform or lobed and subpaniculate; partial inflorescences condensed or with unequal branches, approximate or slightly separated occasionally more distant), up to c. 1.5 cm. long; inflorescence axis glabrous or with multicellular hairs, often concealed by the densely set flowers; peduncle up to 9 cm. long but generally shorter.
    Bracts
    Bracts and bracteoles 2–3 mm. long, broadly deltoid-ovate, membranous, glabrous or marginally ciliate, mucronate with the shortly excurrent midrib, which is furnished with multicellular hairs on its dorsal surface.
    Tepal
    Tepals elliptic-oblong, (3) 3.5–5 mm. long, obtuse or subacute, whitish-membranous with (at least in the dry state) a darker central vitta; midrib shortly excurrent, subtended on each side at the base by one or two pairs of lateral nerves which are evanescent at or a little above the centre of the tepal.
    Filaments
    Filaments with the free apices longer than the basal cup.
    Pistil
    Ovary with numerous ovules (usually c. 13–25); stigmas (2) 3 (4), more or less reflexed, slightly longer than the c. 1–1.5 mm. long style.
    Fruits
    Capsule ovoid, 2–4 mm. long, not exceeding the tepals.
    Seeds
    Seeds black, shiny, lenticular, c. 1 mm., sulcate-punctate with the marginal areolae longer, narrower and more concentric.

    Habit
    Perennial herb, often suffrutescent, varying considerably in habit from a lax creeping or decumbent plant to a scandent climber attaining 4 m. or probably more.
    Stem
    Stem and branches ridged or striate, glabrous or thinly to (not in East Africa) rather densely furnished with brownish multicellular hairs.
    Leaves
    Leaves lanceolate-ovate to broadly or deltoid-ovate, shortly acuminate, glabrous or thinly furnished on the lower surface (especially along the veins) with multicellular hairs, occasionally a few hairs present on the upper surface also; lamina of main stem leaves 3.5–10 × 2.5–5 cm., shortly cuneate to truncate or subcordate at the base, rapidly narrowed and ± decurrent into the slender, 1.5–4 cm. petiole; upper and branch leaves smaller, often narrower and more attenuate to the base.
    Inflorescences
    Inflorescence-axis often concealed amid the dense flowers, glabrous to variably multicellular hairy. Inflorescence of axillary and terminal condensed or branched thyrses, 1.5–8 cm. long and 0.8–2 cm. wide, the uppermost often clustered to form a lobed panicle, lateral clusters of flowers (condensed or unequally branched cymes) approximate to slightly separated, dense or laxer, up to ± 1.5 cm. long; peduncle up to ± 9 cm., but mostly shorter.
    Bracts
    Bracts and bracteoles broadly deltoid-ovate, 2–3 mm., scarious, 1-nerved, glabrous or ± ciliate along the margins and dorsal surface of the nerve with multicellular hairs.
    Perianth
    Perianth-segments elliptic-oblong, (3–)3.5–5 mm., obtuse to subacute, mucronate with the percurrent midrib, pale and membranous, usually with a narrow central dark vitta at least when dry, with 2–4 usually short and sometimes faint lateral nerves (sometimes reaching halfway or more) on each side of the midrib at the base.
    Stamens
    Free portion of filaments longer than the sheath, sinuses rounded with no intermediate teeth.
    Stigma
    Stigmas (2–)3(–4), reflexed, a little shorter than the ± 1 mm. style.
    Ovary
    Ovary multiovulate (mostly ± 13–25).
    Fruits
    Capsule globose, 2–4 mm., included.
    Seeds
    Seeds black, shining, compressed, ± 1 mm., deeply furrowed and punctate, the concentric interrupted grooves more conspicuous towards the margins, the punctae towards the middle.
    Habitat
    In or at the edges of forests; 1060–1520 m.
    Distribution
    T1 U2 U4 throughout tropical western Africa from Senegal to Angola
