چکیده
Two additions and four new species are described from Brazil for the large Geminata clade (Solanum: Solanaceae) bringing the total diversity in the group to 149 species, with 44 of these occurring in Brazil. New species are described from Brazil: Solanumamorimii S.Knapp & Giacomin, sp. nov. from Bahia and adjacent Minas Gerais states, Solanumfilirhachis Giacomin & Stehmann, sp. nov. from Espirito Santo, Solanumpsilophyllum Stehmann & Giacomin, sp. nov. from Minas Gerais and Solanumverticillatum S.Knapp & Stehmann, sp. nov. from São Paulo, Rio de Janeiro and Minas Gerais. Modern character-rich descriptions and lectotypifications are provided for Solanumapiahyense Witasek and Solanumlacteum Vell. All are illustrated, mapped and assessed for conservation status. We also provide a brief analysis of the diversity and endemism of the Geminata clade in Brazil and a key to all 44 Brazilian species.
