tapering : but in the pinnae of a large plant in the 
plate referring to the P. angulare, the pinnules are 
broader, rounder, blunter at top, the auricles at 
their anterior bases larger, and they are all attached 
by short stalks. Though these descriptive differences 
seem to be trifling, nothing can be more dissimilar 
than the image which each one makes upon the eye. 
In all the noses which we see in human faces, how 
different they are, and yet they are all noses. And 
though no two of them may be exactly alike, how 
difficult it would be to describe by words the slight 
variations between them. 
W here pound. — Where not found ? It is abundant 
everywhere. 
Variety — Subtripinnatum. — The little leaves 
or pinnules are themselves cut into little leaves, 
especially the lower ones, which are always the 
most highly developed. This multiplies the sub- 
divisions of the whole frond once more ; so that 
instead of being twice divided, it becomes three 
times divided, or tri-pinnate. The variety decom- 
positum is very similar, if it is not still more divided. 
In other respects the subtripinnatum resembles the 
normal form, though its more lex nature causes it to 
droop with some grace. 
Uses. — 
Where pound. — It is met with in localities 
favourable to vigorous developement. In Boomer 
Lane — the upper part of the lane which diverges 
opposite the Marino, and runs along the east flank 
of Peak Hill. The left-hand side going up Bulver- 
ton Hill Lane. 
Cultivation. — When the common fern of this 
species is removed from the sterile hedgerow into 
garden ground, a more vigorous growth is induced, 
and thus it will frequently develope itself into the 
variety. This remark applies to most ferns. Cultiva- 
tion turns many of them into their varieties.
