چکیده

Four new species of "non-spiny" Solanum from South America are described. Solanumlongifilamentum Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is widespread from Ecuador to Bolivia and is most similar to Solanummacrotonum Dunal from Central and northern South America. Solanumantisuyo Särkinen & S.Knapp, sp. nov. (Morelloid clade) is found on the eastern Andean slopes in Ecuador, Peru and Bolivia and is most similar to the widespread lower elevation species Solanumpolytrichostylum Bitter. Solanumarenicola Särkinen & P.Gonzáles, sp. nov. (Morelloid clade) is found in low elevation habitats on the eastern Andean slopes and in Amazonia of Peru and Bolivia and is most similar to the higher elevation species Solanumaloysiifolium Dunal of Bolivia and Argentina. Solanummariae Särkinen & S.Knapp, sp. nov. (Potato clade) is endemic to Cajamarca Department in Peru, and is most similar to the widespread Solanumcaripense Dunal. Complete descriptions, distributions and preliminary conservation assessments of all new species are given.
