Species list for Solanum section Lycopersicum and allies - the "Tomato clade" (with equivalents in the previously recognized genus Lycopersicon, now part of a monophyletic Solanum); please cite this information as coming from Peralta, Knapp & Spooner, unpublished monograph) [For LA numbers applicable to the new taxa segregated from S. peruvianum see Spooner, D.M., I.E.
