Flora Iranica is a very important reference treatment for the vascular flora of Iran. Two genera, Goldbachia DC. and Tetracme Bunge (Cruciferae), are mentioned in Flora Iranica with only one species each for Iran. Additional species of these genera recorded from Iran since the publication of Flora Iranica are listed and discussed here. For Goldbachia, up to now, the only species recorded for Iran in Flora Iranica is Goldbachia laevigata (M. Bieb.) DC.; but here two other Goldbachia species are recorded for the country for the first time: G. pendula Botsch. and G. verrucosa Komarov. For Tetracme the only species recoded for Iran in Flora Iranica is Tetracme recurvata Bunge. T. quadricornis (Steph.) Bunge was recorded later with only one specimen from Semnan province; and T. contorta Boiss. was recorded from Isfahan province. Here more specimens of T. contorta are recorded for the first time from Khorassan province. Identification keys are given for both genera in Iran below.
