It reaches its most northern location in v.c. 108. Outliers in the Weald are authentic and reflect the oceanic climate of the area; the species is now extinct there. The Agden Reservoir, v.c. 63, record is also verified by a specimen in BM but the Goat land, v.c. 62, record of Druce (Comital Fl.: 381; 1932) is not mapped. We can trace no specimen and as it was growing on a mortared bridge we suspect A .adiantum-nigrum. 00 3 4 3 4
