Zygophyllum is the type genus of the flowering plant family Zygophyllaceae. The genus name is derived from the Ancient Greek ζυγόν ( zygón), meaning "double", and φύλλον ( phyllon), meaning "leaf". It refers to the leaves, each of which have two leaflets.
The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia, Australia, and North and South America.[
Molecular phylogenetic analysis suggested that as previously circumscribed, Zygophyllum was not Monophyly, and the genus was split among a number of other genera, including Augea, Fagonia, Roepera and Tetraena.][ , Plants of the World Online accepted only Roepera of these genera, regarding Augea, Fagonia and Tetraena as synonyms of Zygophyllum.][
