A perennial herb of S.- or S.W.-facing Carboniferous limestone sea-cliffs, in rock crevices, on cliff ledges and in open turf on heavily grazed cliff-slopes, often where there is a thin veneer of blown sand. L. procerum subsp. cambrense is a frequent associate. Lowland.
A perennial herb of cliff ledges and steep S.- to S.W.-facing rocky cliff-slopes of Carboniferous limestone, with Limonium parvum and L. britannicum subsp. transcanalis as frequent associates. Lowland.
A perennial herb of coastal rocks and sea-cliffs. Lowland.
A perennial herb of coastal rocks, sea-cliffs, stabilised shingle, in the upper parts of saltmarshes and saltmarsh-sand dune transitions, and locally on the stonework of sea defences and harbour walls. Lowland.
This is a plant of sea-cliffs and coastal screes, but is also known from a railway bank in Cumberland. Lowland.
A perennial herb of crumbling limestone cliff-slopes, quarry cliffs and rock ledges (England), and in the drier parts of saltmarshes (Ireland). Lowland.
A perennial herb of carboniferous limestone rocks and sea-cliffs. Lowland.
A perennial herb of limestone cliff-slopes, quarry cliffs and rock ledges, in similar habitats to those of subsp. portlandicum. Lowland.
This perennial herb was first described in 1924, and has therefore been recognised longer than many members of the L. binervosum aggregate. It is restricted to a single site where it occurs on steep S.-facing Carboniferous limestone cliff-slopes and in rock crevices. Lowland.
A perennial herb of ungrazed or lightly grazed muddy saltmarshes, occasionally also growing amongst nearby rocks and on the stonework of sea-walls. Its habitats are similar to those of Limonium humile, which often grows with it. Lowland.
