A taxonomic revision of the family Tamaricaceae in Egypt is presented. Twelve species belonging to two genera are reported among which Tamarix chinensis Lour. is a cultivated species. Key to the genera, sections and species based on macroscopical and microscopical characters is given. Representative specimens as well as geographical distribution and habitat for each species are also provided. Tamarix nilotica var. arabica (Bunge) H. Hosni is a new combination while Tamarix arborea (Sieb. ex Ehrenb.) Bunge and T. mannifera (Ehrenb.) Bunge are treated as distinct species.
