The presence of Triplastrum spinulosum (Kisselev) Gauthier-Lievre (Desmidiaceae) in South Africa is reported for the first time. The characters of T. spinulosum varieties spinulosum, indicum (Iyengar & Ramanathan) Gauthier-Lievre and  africanum Gauthier-Lievre were found to be exhibited by specimens collected at Ottosdal in the south-western Transvaal. The differences among specimens of the populations studied are ascribed to variation within one variable species and therefore the varieties  indicum and  africanum are relegated to synonymy.
