were serrated and more decidedly formed, then this would 
be the variety decompositum of Moore. If the lowest 
upper leaflet of a pinna be much larger and longer than the 
rest, and be subdivided into several little leaves, then it is 
his tripinnate Angular Fern. The sub-tripinnate variety is 
very common in the neighbourhood, and the decomposite 
form is also frequently met with. If we see in our hedge- 
banks a group of large, fine, handsome Angular Ferns lying 
together in a dense mass, they are likely to belong to one 
of these forms. 
2. Doubly-serrated Angular Prickly Fern. Biserratum, 
The leaflets are large, broad, and doubly serrated, distinctly 
stalked, and have bristles very conspicuous to the sight. 
The auricle is more deeply separated than the other lobes. 
The frond itself is rather broader than the generality of the 
Prickly Ferns. The stalk is long, and the clusters on the 
back of the frond not so crowded as in some other cases. 
This is a large, handsome Fern, and appears light and 
elegant, though the leaflets exceed the usual size of the 
species . This is not uncommon in most parts of the district. 
3. Tiled or Imbricated Angular Prickly Fern. Imhrica- 
turn. The great characteristic of this variety is, that the 
leaflets are closely tiled and lap over one another. The 
fronds are narrow lance-shaped. The pinnae are short and 
blunt. The leaflets have nearly four equal sides, with an 
auricle sticking out on the side opposite the rachis, and 
have a short bristle at the summit, and the tip of the auricle. 
Only the lowest leaflet of a pinna is stalked, the others are 
decurrent. It is said that this variety has bulbs on the 
stalks, by which new plants may be reared. If we mistake 
not, this grows between Hawkchurch and New Park in the 
parish of Axminster. 
4. Proliferous Angular Prickly Fern. Broliferum. The 
old name given to this by Moore was angustatum, (nar- 
rowed) because its leaflets are narrow and acute. A very 
beautiful specimen of this has been taken from a lane near 
Greenway head, IJplyme. The auricle and the stalks are 
very conspicuous. The pinnae are short and distant from 
one another. The whole frond presents a very light 
appearance. The leaflets are bright green and shining, and 
their narrow lance-shaped form, with the little projection at
