pinnae have frequently two auricles, not only an outer but 
an inner one. The inner one is much the smallest, and 
that only attached to the lowermost leaflets of a pinna. 
These auricles are nearly, if not quite, distinct leaves. This 
is a plant of luxuriant growth, and has its pinnules pin- 
natifld or pinnate, which does not generally happen in this 
species. The frond itself is broader and stronger, though 
the foliage is not stiff* or leathery. It seems questionable 
whether the plant would retain the same form if it were 
placed in a less favourable position for developing itself, 
and whether it would not degenerate into the ordinary 
appearance. The sub-tripinnate variety is very common 
in the neighbourhood. If we see in our hedge-banks a 
group of large, flne, handsome Angular Ferns, lying together 
in a dense mass, they are likely to belong to this form. 
8. Decomposite A. F. Decompositum, This is one of 
the most divided Angular Ferns and is tripinnate. Its 
leaflets have other tiny ones cut out of them, which are 
serrated. This is a large, handsome plant and much 
resembles the preceding, but from being so much divided is 
still the more elegant. There is a spine to each serrature, 
and the leaflets close to the mid-stem, and at some little 
distance from the base, are those which show these little 
leaves to the greatest perfection. Axminster, Colyton, and 
Hawkchurch. 
9. Plumous A. F. jPlumosum, There are three leading 
characters to distinguish this variety. 1. It has a thin 
frond. 2. The under-leaflets of the lowest pinnae are longer 
than the upper ones, while the pinnae themselves are broad. 
3. It is biserrate, i.e., the distinct teeth or serratures of 
the stalked leaflets are again serrated. All the lobes are 
directed forward and cut into sharp teeth. The frond has 
a pale shining green colour and a broad egg-shaped outline. 
The Fern gracefully curves, and when pressed^ becomes as 
thin as paper. M. Charmouth, Colyton, Combpyne, 
Hawkchurch, and Musbury. 
10. Triangular A. F. JDeltoidemi, This has a triangular 
frond. The pinnae also are triangular and overlap each 
other. The frond is about a foot high and the stalk is 
rather long. This has its leaflets decidedly stalked, and the
