fringed with stalked glands. Rachis clothed with long pointed scales, 

 with a dark centre, and diaphanous margin. Height 2 to 4 feet. The 

 largest scales of the full-grown plant should be examined. One of 

 the most common and most generally distributed of British ferns.

 in Wilts. Fronds curved elongate-triangular, subtripinnate. Pin-

1. P. aculeatum, (Roth.) prickly Shield-Fern. Newm. 169. 

 Aspidium, lobatum, Kunze. A. aculeatum and A. lobatum, Sm. 



Locality. On hedge-banks and on the borders of woods and 

 thickets. P. Fl. July, August. Area, 1, 2, 3, 4, 5. Distributed 

 throughout all the Districts. Fronds rigid, lanceolate, or linear- 

 lanceolate, bipinnate. Pinnules confluent, obliquely decurrent, or 

 attached by the point of their wedge-shaped base ; the upper basal 

 ones largest ; all spinose-serrate, more or less auricled at the base. 

 Height 1 to 2 feet. The general outline varies greatly in different 

 specimens, and even in fronds belonging to the same plant, being in 

 some instances almost linear, in others even broadly lanceolate. The 

 rachis is leafy to within a few inches of its base, and is clothed 

 throughout with reddish-brown or rust-coloured scales. A. lobatum 

 (Sm.) has the fronds more rigid, simply pinnate. Pinnae lobed_or 

 pinnatifid.
