The genus Limeum was traditionally recognized as belonging to the familyMolluginaceae, but is now treated as the sole genus in the monotypic family Limeaceae. The family is newly recognized through research by the Angiosperm Phylogeny Group III system to deal with long-standing phylogenetic difficulties in placing various genera within the Caryophyllales.[3][4]Limeum comprises subshrub and herbaceous species native to tropical, eastern and southern Africa, and South Asia.[1] Previously, the genus Macarthuria from Australia was also placed here, but it now is found to belong to Macarthuriaceae.[5]
