27.9 Dryopteris austriaca (Jacq.) Woynar<br />

(D.ddatata (Ho ffm .) A.Gray)<br />

A sub-Atlantic taxon widespread throughout Britain and<br />

Ireland. A variable species occasionally confused with<br />

D.carthusiana because one common form produces stolons,<br />

from the bases of the stipes, which are mistaken for the creeping<br />

rhizome of the latter species. Leaves on such stoloniferous<br />

shoots have pale almost concolorous scales which add to the<br />

confusion; they eventually form a shuttlecock and the stem<br />

continues growth as an erect rhizome.<br />
