Abstract
An updated checklist of the 29 species of Gagea sensu lato in Iran is presented here, with G. dubia as a new record for the Flora of Iran. Gagea kunawurensis and G. fragifera are accepted names for G. stipitata and G. fistulosa, respectively. Gagea calcicola and G. robusta are recently described as new species for the Flora of Iran. Species are placed in four sections. A diagnostic key is provided for both sections and species within the genus. Distribution maps in Iran and Afghanistan are provided for each species.
