In the first part of this monograph mentioned as dubious under Eudryopteris. 
Having now examined the original specimens of D. Wolfii I find no differences

and densely scaly throughout by rigid, 
castaneous, lanceolate, entire scales; the 
coste beneath with numerous similar 
smaller scales. Lamina up to 50 em long, 
ovate, bipinnate below, deeply bipinnati- 
fid upwards. Basal pinnz with the lower 
side somewhat produced ; the basal basiscop
