BiLOBATUM, Wollaston. (Fig. 90.) — Fronds ovate. Subtri- 

 pinnate. Pinnae lanceolate, irregular, sub-depauperate; pinnules 

 variously laciniate, sometimes double, having the large lobe 

 frequently bilobate, from whence its name. This variety was 

 found near Ottery St. Mary, Devonshire, by Mr. G. B. Wollaston, 

 of Chiselhuist, to whom I am indebted for fronds. 



FoLiosuM, Wollaston. (Fig. 91.) — According to the descrip- 

 tion of Mr. Wollaston, this will probably be the most beautiful 

 variety of the foliose or leafy group ever found; at present, 

 however, it is of immature growth. Vivid green in colour. 

 The pinn£B are all inclined to be falcate-imbricate ; opposite 

 below, alternate above, crowded, and overlapping each other. 

 The posterior pinnules are all longer than the anterior ones.
