The flowers are supported by ramose pedicles, which do not grow out of axils; calice campanulate, with five divisions; corolla of a greenish white, monopetalous, with five equal, rotaceous, somewhat reflexed divisions alternating with those of the calix. Five stamens with erect, converging and bilocular anthers; their filaments are short, with the exception of one, which is longer than the rest. Ovary oval, surmounted by a filiform style. Berry spherical with two compartments, of a dark green, with white spots. This solanum grows on the shores around Rio Janeiro, in damp and shady places. We employ the flower.
