Using a computer-aided imaging system, the seed morphometric and colorimetric features of Astragalus terraccianoi, A. tegulensis and A. thermensis - all belonging to Astragalus sect. Melanocercis - were measured and analysed. The results confirmed differences between A. terraccianoi and A. tegulensis, as well as the validity of A. tegulensis. Differences between the Corsican and Sardinian populations of A. terraccianoi were also found.

Abstract
Using a computer-aided imaging system, the seed morphometric and colorimetric features of Astragalus terraccianoi, A. tegulensis and A. thermensis - all belonging to Astragalus sect. Melanocercis - were measured and analysed. The results confirmed differences between A. terraccianoi and A. tegulensis, as well as the validity of A. tegulensis. Differences between the Corsican and Sardinian populations of A. terraccianoi were also found.
