Var. lobatum. Harrow lance-shaped: the first 
pair of pinnules distinct, considerably larger than 
the others, and auricled; the others not auricled 
and decurrent; very rigid and spiny, generally 
smaller than aculeatum. 
Yar. lonchitidioides. —Frond once divided, lax; 
p inn ae crescent-shaped, occasionally deeply cleft. 
P. aculeatum grows sparingly, as far as we have 
observed, in the north of Devon ; we found it near 
Oakhampton and Tiverton, and at Marwood. 
P. lobatum occurs on the elevated parts of Ex¬ 
moor, and near Barnstaple. P. lonchitidioides we 
found near Ilfracombe.

Frond broad lance-shaped, wide at the base ; 
each pinnule with a marked projection on the side 
nearest the midrib, distinctly stalked , serrated; each

There are many named varieties of P. angulare. 
Among others, the following are to be found in 
Devonshire:— 
Yar. hastulatum, a very elegant, light, and feathery 
variety; the pinnules very narrow, with a strikingly 
long auricle, and spiny.
