The Morelloid clade of L. (Solanaceae) in Argentina: nomenclatural changes, three new species and an updated key to all taxa.

Since the publication of the Solanaceae treatment in "Flora Argentina" in 2013 exploration in the country and resolution of outstanding nomenclatural and circumscription issues has resulted in a number of changes to the species of the Morelloid clade of L. (Solanaceae) for Argentina. Here we describe three new species: Chiarini & Cantero, , from wet high elevation areas in Argentina (Catamarca, Salta and Tucumán) and Bolivia (Chuquisaca and Tarija), Barboza & S. Knapp, , from central Argentina in Catamarca, La Pampa, La Rioja, San Juan and San Luis, and Barboza & S. Knapp, , from the mountains of Jujuy, La Rioja, Salta and Tucumán. We provide descriptions, illustrations and distribution maps for all new taxa. A table of nomenclatural changes and additional taxa now known to occur in Argentina summarizes additions and changes since the "Flora Argentina". We also provide an updated key, including all new taxa for the country, to facilitate identification and further exploration.
