A southern sub-Atlantic species whose distribution is mainly<br />

coastal in Britain and Ireland. It reaches its most northern<br />

location in v.c. 108. Outliers in the Weald are authentic and<br />

reflect the oceanic climate of the area; the species is now extinct<br />

there. <strong>The</strong> Agden Reservoir, v.c. 63, record is also verified by a<br />

specimen in BM but the Goat land, v.c. 62, record of Druce<br />

(Comital Fl.: 381; 1932) is not mapped. We can trace no<br />

specimen and as it was growing on a mortared bridge we suspect<br />
