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.
Key words:
Leguminosae, Sardinia,
Corsica, taxonomy, endemism.
