    Prostrate or climbing shrub to 4 m, heavily armed; young stems sparsely stellatepubescent with trichomes porrect, orange-translucent, sessile, rays 6–8, 0.1–0.15 mm, midpoints usually 0.5–1 mm; prickles curved, 1.5–3 mm long, 1–2.5 mm wide at base, round or flattened
    Leaf blades drying concolorous to weakly discolorous, yellow-green to green-brown, elliptic, 6–14 × 4.5–9 cm, ± 2 times longer than wide, base cuneate, often oblique, margin lobed, the lobes 2–5 on each side, deltate, 1–1.7 cm long, acuminate and extending 1/4–1/3 of the distance to the midvein, apex acuminate; sparsely stellate-pubescent on both sides with trichomes on abaxial surface porrect, sessile, rays ± 8, 0.1–0.25 mm, midpoints 0.3–1 mm, trichomes of adaxial surface smaller with midpoints elongated to 1 mm; primary veins 3–5 pairs; petiole 1.2–6 cm, 1/4–1/2 of the leaf length
    Inflorescences not branched, 2–3 cm long, with 1–4 flowers; peduncle 0–5 mm long; rachis 0–0.8 cm long; peduncle and rachis unarmed or with up to 5 prickles; pedicels 0.9–1.3 cm long in flower, in fruit 2.5–3.5 cm long, with 2–10 prickles
    Flowers heterostylous, only 1–2 long-styled, 5- merous
    Calyx 3–4 mm long, the lobes deltate, 1–2 mm long, acuminate, unarmed or with up to 10 prickles
    Corolla white, 1.3–1.6 cm in diameter, lobed for 2/3–3/4 of its length, lobes deltate, 5–6.5 × 2.5–3.5 mm
    Stamens equal; anthers 4–4.5 mm
    Ovary with a few stellate trichomes; style 5.5–7.5 mm long on long-styled flowers
    Berries 1(–2) per infructescence, striped when young, orange at maturity, spherical, 20–25 mm in diameter; fruiting calyx unarmed or with up to 10 prickles
    Seeds 5.5–6 × ± 4.5 mm
    Moist montane forest understorey, CrotonBrachylaenaCalodendrum and Ocotea forests; 1800–2500 m
    Specimens of S. agnewiorum look deceptively similar to the common and hypervariable S. anguivi Lam. as its distinguishing characters in the fruit are easily overlooked due to scarcity of fruiting material. Solanum agnewiorum differs from S. anguivi by its climbing habit, prickles always curved, leaf lobes acuminate, 1–4 flowers and 1–2 fruits per inflorescence, fruits 20–25 mm diameter, and seeds 5.5–6 mm diameter.
