21.7a Asplenium trichomanes L. subsp. trichomanes<br />
Apart from isolated localities in Northumberland, v.c. 68,<br />
subsp. trichomanes is confined to north and central Wales, the<br />
Lake District and Scotland, although in montane levels rather<br />
than at high altitudes. <strong>The</strong> taxon avoids calcareous rocks of any<br />
kind. No specimens have so far been confirmed for Ireland<br />
although the number of specimens seen from there has been<br />
comparatively smaller. <strong>The</strong> subspecies could turn up in v.c. 4<br />
where a hybrid (A. x alternifolium) involving this subspecies<br />
has been found and this parent may yet be found extant.<br />
