Abstract

Seed micromorphology of 14 species of the Astragalus sect. Caprini from Khorasan Razavi Province (NE Iran) was studied using Scanning Electron Microscopy. Three main seed shapes, ovoid, mitiform and reniform, and four types of seed coat ornamentation, rugulate, reticulate–rugulate, velate and velate–foveolate were found. Seed micromorphology of the studied specimens was found to be variable between species. An identification key is presented based on seed coat characters.
