Isatis takhtajanii Avestisian is reported as a new record from western Iran. It is close to I. tinctoria L.; a list of diagnostic differences is provided. A more complete description of I. takhtajanii and a distribution map are given. Isatis koeiei Rech.f. is reduced to a synonym of I. raphanifolia Boiss. Iranian records of I. spectabilis Davis and I. tinctoria subsp. tomentella (Boiss.) Davis are considered to be misidentifications of I. kotschyana Boiss. & Hohen.
