Anther wall formation was studied in32 species belonging to 27 genera of Solanaceae. Dycotiledoneous and basic types of wall formation were observed, as well as several deviations due to subsequent periclinal divisions in the layers formed (middle layers and sometimes endothecium). One type of wall formation was observed in each species. Some genera are uniform in the type of wall formation, while others are heterogeneous; a similar situation was observed at the tribal level. Summarizing all reported information on anther wall formation in the Solanaceae, 64% of the species show the basic type, while the remaining 36% show the dycotiledoneous type. Thus, neither type predominates, and single type characterizes genera, tribes and the entire family.
