    General
    Climbing subshrub, 1–3 m, armed or unarmed; young stems densely stellatepubescent, trichomes porrect, translucent to orange-brown or brown, stalked, stalks 0.1–0.4 mm, rays 7–8, 0.1–0.3 mm, midpoints shorter than rays or up to 0.7 mm; prickles curved downwards or straight, 1–2 mm long, 0.4–0.8 mm wide at base, inconspicuous
    Leaves
    Leaf blades drying somewhat discolorous, red-green or red-yellowgreen, ovate, 6–13 × 3–7 cm, ± 2 times longer than wide, base truncate to cuneate, often unequal or oblique, margin entire to obscurely lobed, the lobes up to 3 on each side, up to 5 mm long, broadly rounded, apically rounded to obtuse and extending up to 1/4 of the distance to the midvein; apex obtuse to acute; densely stellate-pubescent abaxially, trichomes on abaxial surface porrect, stalked, stalks 0.1–0.3(–0.4) mm, rays ± 8, 0.15–0.3 mm, midpoints variable (–0.4 mm), adaxially glabrescent, rays reduced, midpoints reduced(0.8 mm); primary veins 4–5 pairs; petiole 0.5–2 cm, 1/5–1/6 of the leaf length
    Inflorescences
    Inflorescences not branched or branched once, 3.5–7 cm long, with 3–10 flowers; peduncle (2–)6–30 mm long; rachis 0–3 cm long; peduncle and rachis unarmed or with 1 prickle; pedicels 0.8–1 cm long, in fruit 1.5–2.2 cm long, usually unarmed
    Flowers
    Flowers heterostylous, 5-merous, the basal 2–5 long-styled
    Calyx
    Calyx 4–6 mm long, lobes deltate, 2–3 mm long, acute to acuminate, unarmed
    Corolla
    Corolla mauve to purple, 1.8–3 cm in diameter, lobed for ± 2/3 of its length, lobes broadly deltate, 8–12 × 3–6 mm
    Stamens
    Stamens equal; anthers 6–8 mm
    Ovary
    Ovary with sparse simple hairs; style 10–15 mm long on long-styled flowers
    Fruits
    Berries 2–5 per infructescence, striped when young, red at maturity, usually elongate when young, 10–13 mm in diameter
    Seeds
    Seeds 2–2.7 × 1.7–2.2 mm
    Ecology
    Forest understorey, open forest, forest edges or disturbed ground, 300–2000 m
    Note
    Solanum stipitatostellatum includes variable montane populations distinguished by their almost entire reddish leaves on fertile branches, large inflorescences, prickles small or absent, and trichomes with stalks 0.1–0.4 mm long. The fruit is markedly elongate during development and becomes spherical at maturity. The corolla size ranges between 1.8 and 3 cm in diameter; the majority of specimens have a pedunculate inflorescence with 4–10 flowers.  Care must be taken with identification of this species. Most S. stipitatostellatum herbarium material is currently held under S. kitivuense, S. englerianum and S. glochidiatum. Specimens annotated as “sp. near stipitatostellatum” are often attributable to the smaller-leaved savanna species S. taitense. S. stipitatostellatum has some distribution overlap with S. taitense and both taxa have stalked trichomes, but S. stipitatostellatum has mature leaves 6–13 × 3–7 cm, and > 3 (up to 10) flowers per inflorescence, while S. taitense has smaller leaves and fewer flowers per inflorescence. Solanum stipitatostellatum is a larger plant than S. zanzibarense, with larger flowers and long-stalked trichomes, and occurs at higher altitudes than the coastal S. zanzibarense.
