Comparison of the populations of Pelargonium caroli-henrici B. Nord. s. str. and P. caroli-henrici sensu E.M. Marais, based on the thorough analysis of morphological characters, including color and arrangement of nectar guides, corolla morphology, the number and morphology of fertile stamens, filament orientation, pollen presentation mode and leaf lamina morphology led to the conclusion that the populations P. caroli-henrici sensu Marais should be described as а new species P. invertum F. Gren. ex V.I. Troshkina & E.M. Ioganson. Detailed morphological description, a comparative table of diagnostic characters, differentiating the new species from related taxa, color plates of the most important morphological characters distinguishing P. caroli-henrici s. str. and P. invertum are presented. A map of сollection localities of P. caroli-henrici s. str. and P. invertum together with a photo of the P. invertum holotype are provided.
