An annual found in the middle and lower parts of saltmarshes, often with Salicornia species. It is an early colonist of intertidal mud- and sand-flats, sometimes also occurring higher up in salt-pans and drift-lines, on shell and shingle banks, and in thinly vegetated brackish areas behind sea-walls. Lowland.
