Limonium britannicum subsp. transcanalis
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.
This is another taxon which was not recognised at the time of the 1962 Atlas, and hard to separate in the field from other L. britannicum subspecies in S. W. England (subsp. britannicum and subsp. coombense). The distribution is stable, with no evidence of any populations having been lost since it was first described in 1986.
