The monotypic Iranian Zhumeria (Labiatae) was investigated anatomically. The results, taken together with extra taxonomic information available as a result of recent collections, were used to assess its'affinities. The conclusion reached was that although Zhumeria is a most distinct and isolated genus, it has some links with the genera of the tribe Meriandreae of the subfamily Stachyoideae. Drawings illustrate its characteristic anatomical and morpholo­ gical features.
