We describe and illustrate in detail the species of genus Iochroma Benth. (Solanaceae) inhabiting La Libertad Region, Peru, and a new taxon from northern Peru. We report 8 species, of which 7 are Peruvian: I. cachicadanum, I. cornifolium (Ecuador), I. edule, I. lilacinum, I. rubicalyx, I. salpoanum, I. smithianum & I. tupayachanum. Five of them have yellow orange berries and edible wild fruits. We present a new taxon, I. viridescens, which is found in northern Peru, it presents 29-44 flowers per node, arranged in fascicles, corolla dark green in the distal area attenuating toward the basal area outwardly, yellowish-greenish internally, free portion of the staminal filaments creamy white 0.2 0.3 mm long, anthers yellowish with an incipient apical mucro, stigma trilobate. Additionally, we include a dichotomous key to all species; as well as the respective illustrations and photographies, relations with allied species and data about ethnobotany, geographic distribution, ecology, phenology, current status and uses of each species.

Keywords : Iochroma; Solanaceae; edible fruits; La Libertad Region; Peru.
