A TAXONOMIC REVISION OF THE GENUS SISYMBRIUM (BRASSICACEAE) IN IRAN

In a revision of the genus Sisymbrium L. in Iran the specimens of several herbaria were studied, moreover, the studies were completed in the field. Based on the studies an identification key to the Iranian species was constructed. Moreover, full description of the genus and species was prepared for the Flora of Iran. A short list of studied specimens is provided. The results also showed that S. integrimum and S. brassiciforme are synonymous, S. runcinatum var. hirsutum is a true member of the flora of Iran and S. gaubae is a distinct species. Based on these studies S. kermanicum collected from Jebal Barez in Kerman province was formerly described as a new species. Neotorularia aculeolata is transferred again to the genus Sisymbrium as S. aculeolatum. Presence of S. damascenum sometimes recorded from Iran is not proved.
