Astragalus maritimus Moris and A. verrucosus Moris are two endemic threatened species exclusive of South West Sardinia. In this study the populations of both species were characterized and their seed germination investigated. The in situ results allowed reviewing their conservation status in compliance with the IUCN criteria, confirming the CR category by new subcriteria for both species. The germination study allowed identifying as well their dormancy breaking requirements.

Abstract
Astragalus maritimus Moris and A. verrucosus Moris are two endemic threatened species exclusive of South West Sardinia. In this study the populations of both species were characterized and their seed germination investigated. The in situ results allowed reviewing their conservation status in compliance with the IUCN criteria, confirming the CR category by new subcriteria for both species. The germination study allowed identifying as well their dormancy breaking requirements.
