Three new species of “non-spiny' Solanum are described from Peru and Ecuador, and a revised description for Solanum verecundum M.Nee is presented. Solanum kulliwaita S.Knapp, sp. nov. (Dulcamaroid clade) is endemic to the Department of Cuzco in southern Peru, and is most similar to the recently described Solanum sanchez-vegae S.Knapp of northern Peru. Solanum dillonii S.Knapp, sp. nov. (Brevantherum clade) is found in southern Ecuador and northern Peru in the Amotape-Huancabamba phytogeographic zone, and is morphologically similar to the widespread Solanum riparium Ruiz & Pav. Solanum oxapampense S.Knapp, sp. nov., (also of the Brevantherum clade) is endemic to the Oxapampa region (Department of Pasco) of central Peru, and is similar to and segregated from Solanum verecundum M.Nee of Peru and Ecuador. Complete descriptions, distributions and preliminary conservation assessments of all new species are given.
