    Prostrate or climbing subshrub to 4 m, armed; young stems stellate-pubescent, trichomes porrect, translucent to orange-brown, sessile or stalked, stalks up to 0.1 mm, rays 7–8, 0.1–0.15 mm, midpoints short or reduced to glands; prickles straight or curved, 2–4 mm long, 0.8–2 mm wide at base, round or flattened
    Leaf blades drying usually concolorous, yellow-green to red-green, ovate to lanceolate, 3–14 × 1.5–7.5 cm, 2.5–3 times longer than wide, base cuneate, often unequal or oblique, margin lobed, sometimes entire, lobes 2–3 on each side, up to 15 mm long, rounded to deltate (obovate), apically rounded to obtuse, extending up to 1/2(–2/3) of the distance to the midvein; apex acute to obtuse; stellate-pubescent to glabrescent on both sides, trichomes on abaxial surface porrect, stalked, stalks to 0.1 mm, rays (4–)6–8, 0.1–0.2 mm, midpoints short or reduced to glands, adaxially glabrescent, rays reduced to (2–)4–8, often less than 0.1 mm long, sometimes rays almost invisible with only brown globular glands seen; primary veins 4–6 pairs; petiole 0.5–4 cm, 1/3–1/6 of the leaf length
    Inflorescences not branched, 2–5 cm long, with 2–10 flowers; peduncle 0–5 mm long; rachis 0–2.5 cm long; peduncle and rachis usually unarmed; pedicels 0.3–0.7 cm long, in fruit 1.2–1.8 cm long, usually unarmed
    Flowers perfect, 4–5-merous
    Calyx 2–4 mm long, lobes deltate, 0.5–1.5 mm long, acute to acuminate, usually unarmed. Corolla white to mauve, 1.5–2 cm in diameter, lobed for ± 4/5 of its length, lobes narrowly ovate to narrowly deltate or oblong, 6–8(–12) × 1.5–2 mm
    Stamens equal; anthers 4–6.5 mm

    Moist or dry forest, forest edges, rocky outcrops, on sand or sandy loam; 0–700 m
    Solanum zanzibarense can be recognised by its small flowers with long narrow corolla lobes, scrambling or climbing habit, slightly recurved or sometimes straight prickles over 2 mm long, and trichomes with very short stalks and short midpoints. This species includes a wide range of interbreeding populations across coastal East Africa from Kenya to Mozambique, encompassing a variety of leaf shapes and prickle morphologies, stalkedtrichome lobed-leaved populations from Zanzibar ( S. zanzibarense sensu stricto) and glabrescent large-leaved populations from Kenyan and Tanzanian coast (often annotated as S. vagans). None of the distinguishing characters can alone separate all specimens, but the combination of leaf size and shape, trichome stalk length, calyx lobe shape and flower size correlates with geographical distribution. Like many similar climbing spiny Solanum species treated here, S. zanzibarense occurs sporadically over a large geographical area but can be difficult to find outside its flowering season.
