A perennial herb of coastal rocks and sea-cliffs, especially favouring S.-facing cliffs of Quaternary head deposits of unconsolidated sand and rock fragments. Lowland.
A perennial herb of coastal rocks and sea-cliffs, pebble beaches and the drier parts of saltmarshes. Some of the largest populations are on S.-facing cliffs of Carboniferous limestone in Pembrokeshire. Lowland.
A perennial herb found mainly on chalk sea-cliffs, but with a few small outlying populations on stabilised shingle (Chesil Beach), on limestone at Lulworth and on Purbeck, and on breakwaters in Portland Harbour (all in Dorset). Lowland.
A perennial herb of ungrazed or lightly grazed muddy estuarine saltmarshes, often growing in close proximity to its commoner relative, L. vulgare, but replacing it in some areas. It rarely occurs on rocky cliffs. Lowland.
A deciduous perennial herb found as a well-naturalised garden escape on and around chalk cliffs at Rottingdean and Seaford (E. Sussex) and on the sea front at West Bay (Dorset). It grows with alien populations of Frankenia laevis at both localities, and is apparently spread by gulls. Lowland.
A deciduous perennial herb found as a naturalised garden escape and relic of cultivation in fields, rough grassland, railways and on sea cliffs. Lowland.
A perennial herb of granitic sea-cliffs, coastal rocks and screes. Lowland.
A perennial apomictic herb of stabilised sand dunes (St Ouen`s Bay, Jersey) and coastal rocks (St Esquère Bay, Alderney), in the latter site growing with L. binervosum subsp. sarniense. Lowland.
A perennial herb restricted to a single site where it occurs on basic igneous rock outcrops, along the seaward edge of cliff-tops and on inaccessible cliff ledges. Lowland.
