Solanum lycocarpum A.St.Hil. is a widely distributed and well adapted shrub of cerrado areas in Brazil. Anatomic studies of the leaves of 60 days old plants obtained from seeds germinated at the greenhouse were carried out. Transversal and paradermal sections were prepared using the usual microthecniques. Both leaf surfaces are covered with simple glandular and non-glandular trichomes, and stellate trichomes. At front sight, the walls of the epidermal cells are sinuous with stomata occurring on both upper and lower surfaces. At cross-section it is observed that the epidermis consists of a single layer of cells and the mesophyll is dorsiventral. The palisade parenchyma consists of a single layer of cells and the parenchyma which is faced to abaxial surface is shaped by three to five layers of cells with compact arrangement. The results constitute a basic reference for further studies about this species, on this stage of development.
