The genus Iphiona Cass. emend. A. Anderb. (Compositae‐Inuleae‐Inulinae) is revised and considerably amended. The former genera Grantia Boiss. (= Perralde‐riopsis Rauschert) and Hirschia Baker are included as well as the major part of Iphiona Cass. s.str. and the species Inula grantioides Boiss., and Pulicaria phillipsiae S. Moore. Five new combinations are made: I. anthemidifolia (Baker) A. Anderb., I. arachnoidea (Boiss.) A. Anderb., I. grantioides (Boiss.) A. Anderb., I. phillipsiae (S. Moore) A. Anderb., and I. senecionoides (Baker) A. Anderb. The new species I. teretifolia A. Anderb. is described. A discussion of the phylogeny of the group and a cladogram, involving reticulation, of the Iphiona species are presented. The 11 species are distributed in Egypt, Israel, Jordan, Sudan, Ethiopia, Somalia, Saudi Arabia, Peoples Democratic Republic Yemen, Oman, Iran and Pakistan.
