Tracheophyta MagnoliopsidaCaryophyllaceaeSaginaSagina maritima


An annual of maritime rock crevices, cliff-tops, stabilised shingle, dune-slacks and disturbed areas in upper saltmarsh on sandy substrates; also on walls and tracks, in pavements and on sandy roadsides near the sea. A form of it, described as var. alpina, has been recorded at 1210 m on Ben Nevis (Westerness), though the identity of such plants requires confirmation.
