Iran with possessing more than 850 species is one of the most important centers of origin of the genus Astragalus, with high amount of endemism. One of the complicated sections among this genus is section Hymenostegis. Astragalus vernaculus Podlech belonging to this section is considered as an endemic species of Isfahan province and is distributed only in western parts of this province. Based on the IUCN guidelines and using three criteria including extent of occurrence, area of occupancy and number of mature individuals, the conservation status of this endemic species was determined and classified as “Critically Endangered”. In addition, some notes regarding the taxonomy of this species are provided. Due to the growing of this species in unprotected areas, in order to prevent extinction and degradation of its habitats, announcement of protected areas is necessary in these habitats.
