Leaves to 7 cm wide and 25 cm long, broadly lanceolate, margins sometimes slightly revolute, acuminate apically and basally, above scabrous with dispersed, sessile, porrect, pauciradiate stellae, beneath with somewhat larger but similar hairs; minor leaves wanting. Inflorescence a long-stalked, many-flowered cyme standing well above the foliage, the peduncle to 20 cm long, branching in the upper portion, puberulent to tomentose with sessile, porrect stellae, pedicels 2-9 mm long, slender, pubescent, abscissing almost at the base. Flowers with the calyx 3-5 mm long, lobed to half- way down, the lobes deltoid, a glabrate region at the base of the calyx often drying dark or appearing swollen but not forming a large and conspicuous annular enlargement; corolla white, drying yellowish-brown, 15 mm across, lobed to more than halfway down; anthers 3 mm long, the filaments glabrous; ovary glabrous or pubescent. Fruits yellow, glabrescent, 9-11 mm across; seeds 2 mm long.
Habit Shrub or tree
Note Solanum rugosum is similar to S. asperum but differs in having broader leaves which are more pubescent above and have sessile stellate hairs beneath. The dark area at the base of the calyx is useful in recognition of dried specimens. This species occurs at roadsides and in forest openings in lowland and middle elevation areas in Panama. The species ranges from British Honduras to Brazil and is present in both Greater and Lesser Antilles.
Distribution ranges from British Honduras to Brazil and is present in both Greater and Lesser Antilles.
