''Capparis sepiaria'' is variable and several varieties have been distinguished.
''Capparis'' has been considered to comprise approximately 250 species and to occur in all tropical and subtropical regions. However, the genus was found to be polyphyletic, and most species from tropical America have been transferred to separate genera. About 12 species are found in mainland tropical Africa. Several other ''Capparis'' spp. are used in traditional medicine in tropical Africa. Some of these are more important for their edible fruits (''[[Capparis decidua]]'' (Forssk.) Edgew., ''[[Capparis erythrocarpos]]'' Isert, ''[[Capparis hereroensis]]'' Schinz) or as spice and condiment (''[[Capparis spinosa]]'' L.).
