An annual which has been long-naturalised on shingle in Sussex and has recently been found at a similar site in S. Hampshire. Elsewhere it occurs as a casual on waste ground and rubbish tips, where it possibly arises as a wool alien. Lowland.
T. stellatum was recorded from the wild in Britain in 1804 at Shoreham (W. Sussex), where it has been known ever since. It appears to have declined as a casual; most records of such occurrences were made before 1930.
Native of the Mediterranean region and S.W. Asia; naturalised in Australia.
