THE MOUNTAIN PARSLEY FERN. 
The segments or leaflets into which they are cut are 
more or less wedge-shaped and notched or cleft at 
their ends. The fertile fronds have the leaflets of an 
oval or oblong or linear form. The venation of the 
barren fronds consists of a slender vein extending 
along each pinnnle, casting off* another into each of 
its lobes, this again alternately branching, one branch 
being directed towards every marginal point. In the 
fertile fronds a midvein enters each ultimate division 
and passes sinnonsly to its point, throwing ont nearly 
to the margin alternate veins, usually simple but 
sometimes forked, bearing a sorus near their ends. 
The fructification usually occupies the whole system. 
The sori small, roundish, at first distinct though con- 
tiguous* ultimately becoming laterally confluent and 
forming a continuous line. Spore-cases small, elliptic 
obovate, stalked. Spores smooth, roundish, oblong 
or bluntly triangular. 
The Mountain Parsley Fern is peculiarly a mountain 
plant, delighting in the shades and corners of boulders, 
and to be among loose slate-stones, and at the feet of 
the unmortared walls that wind about the fells and 
mountains. It is well-fitted therefore for garden 
rockeries ; but it is apt to die off in winter if allowed 
to be too damp.
