Solanum lanceifolium Jacq.

Vine, 1-100 m long, sometimes shrub-like; stems glabrate to stellate-tomentose, often with stout bristles, armed with short, recurved spines. Leaves 3-25 cm long and 2-10 cm broad, lanceolate to elliptic, entire or usually with sinuate-dentate margins, glabrate to tomentose or hispid with mostly sessile stellae, armed on the midrib or minor veins; petioles mostly armed, less than 1/3 the length of the leaf. Inflorescence lateral, few-to several-flowered; peduncle short, mostly un-branched, 5-15 mm long, filiform, becoming longer and stouter in fruit. Flowers mostly small; calyx 1-2 mm long with the lobes ca. 1 mm long, splitting at the sutures and enlarging in fruit, often armed with straight spines; corolla (Panama) mauve to purple outside, white inside, divided almost to the base, pubescent outside, the lobes often recurving 7-12 mm long; anthers slender and tapering to the tips, converging to form a tube or free, about as long as the corolla lobes.

It is a tropical plant.
