A new species of the Streptocarpus rexii aggregate is described from Itala Game Reserve in KwaZulu-Natal, South Africa. The geographic isolation of S. kunhardtii, its pale methyl violet flowers, and long fruits distinguish it from S. roseoalbus, its closest relative. A second new species, S. hilburtianus, is described from two high-altitude localities in Mapumalanga, South Africa. The alliances of this species are unclear, although corolla coloration and leaf vestiture approach S. galpinii; however, it differs in its cylindrical corolla tube, its much shorter pedicels, and its distinctive pollen.
