Range & Status
A rather small species that prefers vertical, sunny, often south-facing serpentine rockfaces near the sea. Very occasionally fertile. In Britain this species is confined to a few sites on the Lizard Peninsula, in the Kynance Cove area on the west coast and at Eastern Cliff and Black Head on the east coast. Elsewhere it is known from the Mediterranean countries of Portugal, Spain, Italy, the former Yugoslavia and Morocco. The Lizard sites lie within a NNR. There are no immediate threats to this species.
