Abstract

Within the Astragalus genargenteus complex three morphologically, ecologically and chorologically well differentiated taxa are distinguished: A. genargenteus from siliceous substrate in the Gennargentu massif (central Sardinia) and two species described as new to science, A. gennarii from limestone on Monte Albo (NE Sardinia) and A. greuteri, widespread on siliceous substrate in the Corsican mountains. The relationship of these species with the allied, spine cushion-like A. sirinicus and A. angustifolius is examined. A key to the species and illustrations are given.
