272 THE BRITISH FERNS. 
There is no doubt that this is a species distinct from C. fragilis. 
It is analogous in size with the smaller forms of the latter, but is 
more finely divided ; the segments of its pinnules are either narrow- 
oblong or linear ; and the teeth are either blunt or more commonly 
emarginate. The veins very frequently terminate in the notch at 
the apex of the tooth, instead of the projecting point of the tooth, as 
is the case in C. fragilis. 
The present is an easily grown plant, either in well-drained pots 
of free open soil, such as light loam and turfy peat mixed with sand, 
or in well-drained sheltered situations, in open rockeries if the soil is 
made congenial. It is more liable than the commoner species to 
suffer from damp while at rest in winter, and hence water should 
not be allowed to collect about it at that season. There is no 
other difficulty in cultivating it, and it forms an elegant small pot 
fern, increased with facility by division.
