Rhizoma quasi-tufted, but increasing laterally ; stipes

 pinnae ascending; pinnules distinct. 



A small, elegant, and fragile fern, common in Wales, the 

 North of England, Scotland, and parts of Ireland.

 Cystopteris dentata, Bah. 412, ad partem, i. e., excl. den- 

 tata, Sm. 



Rhizoma tufted ; stipes much shorter than the frond ; 

 frond ovate -lanceolate; pinnae crowded, overlapping, twist- 

 ed as in Polystichum Lonchitis, scarcely pinnatifid, never 

 pinnate, very broad and obtuse, their divisions slightly 

 notched ; clusters of capsules small, round, remaining dis- 

 tinct, submarginal ; involucre generally wanting. 



Rare ; found by Dr. Dickie in a cave by the sea near 

 Aberdeen. 



Obs. — Tliis little fern is better known to cultivators than to field- 

 botanists. It has exactly the habit of a Woodsia : I only know it as 

 cultivated, and then it appeal's perfectly distinct. It is reproduced rea- 

 dily from seed, and loses none of its distinguishing characters.
