A Boraginaceae species, Solenanthus minimus Brand, described from the territory of Iran is neotypified due to lack of any available original material. In the present paper, it is assigned to the genus Rindera based on newly collected material and original description. Thus, Cynoglossum minimum (Brand) Greuter & Stier is treated here as a synonym for R. bungei (Boiss.) Gürke.
