Abstract
An emended description of Iranian endemic Astragalus durandianus is provided with illustrations and extra information on several morphological characters not indicated in the protologue, including corolla characteristics, the habit size, peduncle length, bigger fruit size, black hairs on the fruits and several other differences. Based on field observations, a brief description of the habitat and data on ecology and biogeography of the species are provided. The conservation status of all species of Astragalus section Trachycercis in the Iranian plateau is evaluated.
