Solanum cutervanum Zahlbr.

Shrubs to small trees, 1–7 m tall. Stems and leaves densely covered with loosely branching golden tree-like trichomes; leaf scars somewhat raised, the stem not winged; new growth densely pubescent with golden tree-like trichomes above and below. Bark of older stems dark reddish-brown, sparsely pubescent with the tree-like trichomes of the young stems. Sympodial units plurifoliate. Leaves simple, 6.5–13 cm long, 1.7–5 cm wide, elliptic or occasionally narrowly elliptic (type), the upper surfaces of the blades drying dark, sparsely pubescent with golden tree-like trichomes, these mostly along the veins, the lower surfaces pubescent with golden trichomes like those of the upper surfaces, the pubescence denser than that above; primary veins 8–12 pairs, sparsely pubescent; base acute, not winged on to the petiole; margins entire, not markedly revolute; apex acute; petiole 0.5–2 cm long, densely golden pubescent. Inflorescences terminal, later appearing lateral or in the fork of the branches, 4–10 cm long, pyramidal, branching ca. 10 times, with 10–20 flowers densely pubescent with loose golden tree-like trichomes like those of the young stems; peduncle 1–4 cm long; pedicels 0.7–1.3 cm long, ca. 0.5 mm in diameter at the base tapering to an apical diameter of 1 mm, slightly nodding at anthesis, densely pubescent with golden tree-like trichomes, articulated at the base and inserted in a sleeve ca. 0.5 mm long; pedicel scars closely spaced and congested at the inflorescence branch tips. Buds ellipsoid, the corolla strongly exserted from the calyx tube. Flowers all perfect, 5-merous. Calyx tube 1.5–2 mm long, conical, the lobes deltate, 1.5–2 mm long, densely pubescent abaxially with golden tree-like trichomes, densely pubescent adaxially with dendritic and simple trichomes. Corolla 1.5–1.8 cm in diameter, violet or occasionally white, lobed 3/4 of the way to the base, the lobes 7–8 mm long, 4–5 mm wide, planar at anthesis, densely pubescent abaxially with tiny dendritic trichomes, these denser at the tips of the lobes, adaxial surfaces glabrous. Filament tube absent; free portion of the filaments 1–1.5 mm long, occasionally slightly pubescent near the base; anthers 3.4–4 mm long, 1–1.5 mm wide, loosely connivent, poricidal at the tips, the pores becoming slit-like with age. Ovary glabrous or with a few dendritic trichomes at the apex, glabrate in fruit; style 5–7 mm long, sparsely to densely pubescent at the base or along its entire length with golden dendritic trichomes; stigma bilobed, the surface minutely papillose. Fruit a globose, purplish-black berry, with thin pericarp, 1–1.2 cm in diameter; fruiting pedicels 1–1.5 cm long, woody, nodding to more or less erect, ca. 1 mm in diameter at the base. Seeds ca. 8–10 per fruit, 3–4 mm × 2.5–3.5 mm, flattened lenticular, reddish-brown, the surfaces minutely pitted. Chromosome number: not known.
