Solanum flaccidum Vell.

Woody vine, twining by petioles. Stems glabrous to densely white pubescent with simple uniseriate trichomes 0.25–0.5 mm long; new growth densely white pubescent with simple uniseriate trichomes ca. 0.5 mm long. Bark of older stems reddish brown. Sympodial units plurifoliate, not geminate. Leaves simple or more rarely pinnatifid with 1–3 lobes, 2.5–9 cm long, 1–4 cm wide, ovate or obovate to triangular or elliptic, membranous, the upper surfaces glabrous to sparsely pubescent with simple uniseriate trichomes, these always present on the midrib, the lower surfaces pubescent with simple uniseriate trichomes ca. 0.5 mm long, these in tufts in the vein axils to densely distributed over the entire lamina; primary veins 7–9 pairs, the midrib pubescent adaxially; base truncate to slightly cordate, often asymmetric; margins entire to lobed, the lobes to 1 cm long, pinched in at the base; apex acute; petioles 1–5 cm long, glabrous to densely white-pubescent, curling and twining. Inflorescences terminal or very occasionally lateral, 1–9 cm long, many times branched, with 10–50 flowers, glabrous to densely pubescent with simple uniseriate trichomes ca. 0.5 mm long, the transition from stem to inflorescence not always clear; peduncle ca. 1 cm long; pedicels 1–1.5 cm long, slender, ca. 0.5 mm in diameter at the base, 0.5–1 mm in diameter at the apex, spreading at anthesis, glabrous to sparsely pubescent with simple trichomes, articulated at the base from a small sleeve; pedicel scars irregularly spaced 0.5–1 cm apart. Buds ellipsoid to fusiform, the corolla strongly exserted from the calyx tube before anthesis. Flowers all perfect, 5-merous. Calyx tube 2–2.5 mm long, conical, the lobes 1–1.5 mm long, broadly deltate, glabrous or sparsely pubescent. Corolla 2.3–2.5 cm in diameter, violet or purple, fading to white, rotate-stellate, lobed ca. 1/2 way to the base, the lobes 6–9 mm long, 5–8 mm wide, spreading or planar at anthesis, densely pubescent abaxially with simple uniseriate trichomes < 0.25 mm long, glabrous adaxially. Filament tube minute, free portion of filaments unequal, one filament 3–3.5 mm long, the others 2–2.5 mm long, the long filament equalling the others early in anthesis, lengthening with flower age, all filaments glabrous; anthers 4.5–5 mm long, 1–1.5 mm wide, ellipsoid, loosely connivent, yellow, poricidal at the tips, the pores lengthening to slits with age or not. Ovary glabrous; style 8–10 mm long, glabrous; stigma clavate, the surface minutely papillose. Fruit a globose berry, 0.9–1 cm in diameter, green (immature?), probably shiny at maturity, glabrous the pericarp thin; fruiting pedicels 2–2.5 cm long, ca. 1 mm in diameter at the base (immature?), woody, pendent. Seeds not observed from mature berries. Chromosome number: not known.
