25.1 Woodsia ilvensis (L.) R.Br.<br />
A northern-montane species which has become very rare<br />
through over-collecting and is now protected by the<br />
Conservation of Wild Creatures and Wild Plants Act, 1975. <strong>The</strong><br />
history and distribution of this species is discussed in detail by<br />
M.H.Rickard in Br. Fern Gaz., 10: 269-275; 1972. Small plants<br />
of W.ilvensis can look very similar to young plants of<br />
Cystopteris fragilis grown in exposed situations.<br />
All squares from which the species has at some time been<br />
verified are indicated by solid dots.<br />
