Notes

Gilbert (1993) revised the genus and accepted seven species, however, Bissinger & al. (2014) found all species to be polyphyletic and suggested to treat them as one polymorphic species or species complex, Gisekia pharnaceoides agg. Gisekia pharnaceoides is a C4 species with atriplicoid Kranz anatomy and NAD-ME biochemical type. The lineage originated in South Africa and presumably migrated along arid areas of eastern Africa during the Late Miocene/Pliocene (Bissinger & al. 2014).
