? Cystopteris dentata, Bab. 412, ad partem, i. e., excl. Dic- 
kieanum, Sim. 
Bhizoma quasi-tufted, hut 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, Bab. 412, ad partem, i. c., excl. den- 
tata, Sm. 
Bhizoma tufted ; stipes much shorter than the frond ; 
frond ovate-lanceolate; pinnae crowded, overlapping, twist- 
ed as in Polysticlium Lonchitis, scarcely pinnatificl, never 
pinnate, very broad and obtuse, their divisions slightly 
notched ; clusters of capsules small, round, remaining dis- 
tinct, submarginal ; involucre generally wanting. 
Bare ; found by Dr. Dickie in a cave by the sea near 
Aberdeen. 
Obs. — This 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 appears perfectly distinct. It is reproduced rea- 
dily from seed, and loses none of its distinguishing characters.
