Resumen:
ABSTRACT. Solanum section Lycopersicon (Solanaceae) includes the cultivated tomato (S. lycopersicum)  and 12 additional wild relatives, endemic to western South America from Ecuador to northern Bolivia and Chile, and with two endemic species in the Gal├ípagos Islands; weedy escaped forms of S. lycopersicum are distributed worldwide. Two species in Solanum section Juglandifolia, distributed in Colombia, Ecuador, and Peru, are sister to section Lycopersicon, and two species of Solanum section Lycopersicoides, distributed in southern Peru and northern Chile, are sister to sections Lycopersicon and Juglandifolia. The delimitation and relationships of wild tomatoes have differed widely depending upon whether morphological or biological species concepts are considered more important. Our monograph summarizes recent morphological and molecular studies of section Lycopersicon, section Juglandifolia, and section Lycopersicoides, and utilizes data from herbarium specimens and observations of germplasm accessions of all species grown in gardens. We recognize four species from the previously polymorphic S. peruvianum sensu lato: S. arcanum, S. corneliomulleri, S. huaylasense, and S. peruvianum sensu stricto, and recognize section Lycopersicoides at sectional level for the first time. Full descriptions and synonymies (including designations of lectotypes), illustrations, distribution maps, and an extensive list of localities are provided for all of tomato and outgroup species.
