Two new non-spiny Solanum species from the Bolivian Andes (Morelloid Clade)

Two new Bolivian species are described from the Morelloid clade of Solanum (section Solanum in the traditional sense). Solanum alliariifolium M.Nee & Särkinen, sp. nov. is found in montane forests between 1,900 and 3,200 m and is morphologically most similar to S. leptocaulon Van Heurck & Müll.Arg., also from montane forests in southern Peru and Bolivia. Solanum rhizomatum Särkinen & M.Nee, sp. nov. is found in seasonally dry forests and matorral vegetation in lower elevations between 1,300 and 2,900 m and is most similar to S. pygmaeum Cav., a species native to sub-tropical Argentina but introduced in subtropical and temperate areas worldwide
