Bulnesia (Zygophyllaceae) is a South American genus consisting of nine species distributed into two subgenera: Gonopterodendron and Bulnesia. Cladistic analyses of the genus was performed using 90 characters from seed protein electrophoresis. Fourteen most parsimonious cladograms were generated with 26 steps and a very high consistency index of 0.95. Out of the 90 bands analyzed, 8 were informative characters because they did not represent autoapomorphies or genus synapomorphies. Out of the 14 cladograms obtained, two had a topology that support the genus subdivision previously inferred by systematic studies based on morphologic, cytogenetic and other biochemical characters. The evolutionary relationships among species are briefly discussed.
