Solanum amorimii S. Knapp & Giacomin

Shrub to small treelet 0.5–3 m tall; young stems terete, glabrous or minutely puberulent with simple uniseriate trichomes to 0.5 mm long; new growth glabrous; bark of older stems smooth, greenish brown. Sympodial units difoliate, geminate; leaves of a pair not differing in shape. Leaves simple, the major leaves 8–10(-15) cm long, 2–3(-5) cm wide, elliptic to obovate, usually widest near the middle or in the distal half, glabrous on both surfaces, fleshy in texture; primary veins 8 pairs, usually paler than the lamina; base sessile and more or less auriculate; margins entire; apex attenuate; petiole absent or < 0.1 cm long; minor leaves 3–5 cm long, 1–2 cm wide, differing from the majors only in size. Inflorescence 0.1–0.3 cm long, opposite the leaves, unbranched, with 4–7 flowers, glabrous; peduncle < 0.1 cm long; pedicels ca. 0.8 cm long, 0.5 mm in diameter at the base and apex, filiform, nodding at anthesis, glabrous, articulated at the base; pedicel scars tightly packed and almost overlapping. Buds ellipsoid to rounded, the corolla exserted ca. halfway from the calyx tube just before anthesis. Flowers 5-merous, perfect. Calyx tube 1.5–2 mm long, conical, the lobes 2–3 mm long, ca. 1 mm wide, narrowly deltate to long-triangular with a 1–1.5 mm long projection that in live plants is a fleshy knob, glabrous. Corolla 0.8–1 cm in diameter, white, stellate, lobed ½ to 2/3 of the way to the base, the lobes ca. 0.4 cm long, 0.2 cm wide, planar at anthesis, minutely puberlent at the tips and along margins. Stamens 3–4 mm long; filament tube ca. 0.5 mm long, the free portion of the filaments <0.5 mm long, glabrous; anthers 2.5–3.5 mm long, ca. 1 mm wide, ellipsoid, yellow, poricidal at the tips, the pores elongating to longitudinal slits with age. Ovary glabrous; style 4–5 mm long, glabrous; stigma minutely capitate, the surface minutely papillose. Fruit a globose or depressed globose berry, ca. 1 cm in diameter, green or pale whitish green, glabrous, the pericarp thick, not markedly shiny; fruiting pedicels ca. 1.5 cm long, ca. 3 mm in diameter at the apex, woody, deflexed; calyx lobes in fruit persistent and slightly elongating, occasionally breaking off but always with > 1 mm remnants. Seeds ca. 30 per berry, not known from mature fruit.

Endemic to eastern Brazil in the states of Minas Gerais and Bahia, known from northernmost Minas Gerais and southern Bahia (Figure 3).
