    Type
    Type: Uganda, Ruwenzori Mts, Doggett s.n. (K!, holo.)
    Habit
    Scrambling or creeping shrub or liana, vine or herb, reaching 10 m in height, often using other vegetation as support;
    Stem
    Stems woody basally or herbaceous, often purplish, usually angulate, often lenticellate; all parts densely (when ochraceous) to moderately pubescent with mixture of simple and complexely branched (but not stellate) hairs up to 1.5 mm long, or glabrescent with only scattered and usually simple long hairs
    Leaves
    Leaves alternate, lanceolate to linear-lanceolate, rarely ovate, membranaceous to coriaceous, dark green above, if pubescent mealy and yellow/green below, (4–)5.6–12 × 2.5–6 cm, bases cordate to cuneate and decurrent, margins entire, apices acute to acuminate; venation often prominent, surfaces pubescent above with pilose margins, glabrescent; pubescent and ochraceous on lower surfaces, with hairs branched and thicker on veins and midribs; domatia usually present; petioles 1–4 cm long, often twisted or curved to facilitate climbing and subtended by two small ovate leaves
    Inflorescences
    Inflorescences subterminal, multiply branched (candelabra-like), lax panicles with umbellate fascicles of 2–3(–5) flowers, often pendulous, (7–)10–28 cm long, 20–80+-flowered; peduncles (1–)2–7.5 cm long often becoming woody; pedicels erect, 0.5–3 cm long in flower, up to 2.5 cm long and expanded beneath calyx in fruit; axes densely tomentose/ochraceous to glabrous, hairs complexely branched and often in clumps
    Calyx
    Calyx campanulate, 3.5–8 mm long, often tinged purple, pubescent and ochraceous with short branched hairs or glabrescent externally; lobes narrowly triangular to lanceolate, sometimes unequal, 1.5–5 × 1.5–3 mm, acute, apices often reflexed, usually with apical tufts of hairs; becoming adherent/accrescent in fruit when 3–6 × 2–4 mm
    Corolla
    Corolla purple, lilac or blue, rarely whitish, with greenish basal star, rotate/stellate to stellate, 1.8–3(–4) cm diameter, tube 1–2.5(–3) mm long; lobes broadly to narrowly triangular, 3.5–12 × 3.5–8 mm, pubescent externally with short usually branched hairs, semi-reflexed to lateral exposing androecium after anthesis
    Stamens
    Stamens often unequal with one longer; filaments free for 1–3.5 mm, pubescent to glabrescent; anthers yellow to yelloworange with orange-brown apices, 2.5–4 × 1–1.5 mm, free
    Ovary
    Ovary whitish, 1–1.5 × 0.8–1 mm, glabrous, bilocular; style straight, white, glabrous, included when 2.5–4.5 mm long or exserted to 3.5 mm when 6–9.5 × 0.2–0.4 mm; stigma green, usually clavate, sometimes capitate, bilobed or clasping, 0.3–0.4 × 0.3–0.8 mm
    Fruits
    Fruit smooth, black, globose to ovoid with coriaceous pericarp, 5–9 mm diameter
    Seeds
    Seeds up to 8–18 per berry, light to dark brown, orbicular to discoid, 2.2–3.5 × 1.8–2.9 mm, often angled, foveolate; sclerotic granules absent.
    Note
    Several authors including Polhill (1961), Jaeger (1985), Hepper & Jaeger (1986) and Beentje (1994) suggested that this taxon is composed of two subspecies. Specimens from NE Africa confirmed these observations and showed that these can be differentiated by their indumentum and geographical distributions.
