Fig. 212. — Middle pinna. 



Oreopteroides, Lowe. (Fig. 212.) — An elegant variety 

 found in the Cumberland Lake district by Miss Beever, This 

 form has fronds that more nearly resemble Lastrea oreopteris 

 than those of any other variety, and as it is slightly scented, 

 I have named it after that Fern. Pinnse subopposite, distant 

 except near the apex, narrow and acuminate except the basal 

 pair, which are elongate-triangular owing to the great size, 

 comparatively, of the lower pinnules. The basal pinnules 

 alone serrate. Sori copious on the upper portion of the 

 frond, becoming confluent. Stipes and rachis slightly scaly.

PixNATiFiDA, Loice. (Fig. 213.)— This singular Fern was 

 found in Westmoreland by Miss Beever. Length of frond 

 twenty-four to thirty inches; colour a leaden blue. Finns
