pre-printTwo new species of Solanum (Solanaceae) from eastern Brazil are described. Solanum anisocladum Giacomin & Stehmann is similar to S. megalochiton Mart., but differs by the indument of the adaxial leaf surface, which is composed of long porrect-stellate and unbranched trichomes. It also has a more robust habit and a unique branching pattern of the flowering stems. It is restricted to the Atlantic Rainforest of northeastern Brazil and was previously misidentified as S. megalochiton. The other species, Solanum caelicolum Giacomin & Stehmann, is endemic to Espírito Santo state and is most similar to S. hirtellum (Spreng.) Hassl., but differs mainly by its adaxial leaf indument, with porrect-stellate trichomes with a central ray smaller than the lateral ones, by its comparatively larger fruiting calyx that can reach up to three times the diameter of the mature berry and by its sessile to subsessile unbranched congested inflorescence. Both species belong to the Brevantherum clade, one of the main lineages identified in the genus Solanum, and are placed together in a clade which contains species from S. sects. Extensum D'Arcy and Stellatigeminatum Child. Complete descriptions, distributions, and preliminary conservation assessments of the new species are given
