as a weed everywhere. It was originally introduced from

D. BLECHNOIDES (Blechnum-like), Fig. 22. An Australian 



Fern, very similar to the last species, but may be distinguished

A small genus of Ferns, separated from Pteris by Mr.

 One of the species has fronds in that form. The genus may 

 be known by the spore-masses being narrow, placed on the
