99 
leaflets are blunt. The leaflets are broadly egg-shaped 
when the auricles are cut off, and serrate or biserrate, with a 
spine sticking out at the apex. M. Wootton. 
24. Bent-leaf A. B. Mejlexmi, The bent-down leaflets, 
with the acute angle of the auricles, and papery texture 
of the fronds, are quite sufficient to determine this plant. 
M. Hawkchurch and Kilmington. 
25. Winged A. B. JBterophorum. This is simply pin- 
nate. The mid-stem of each pinna is winged or has a leafy 
appendage. There are, strictly speaking, no leaflets, but 
lobes, which seldom have an auricle, neither are the 
serratures very apparent. The stalk and mid-stem are 
slightly scaly. M. Colyton and Shute. ^ 
26. Moly’s Winged A. B. ^tero'pTiorum Molyi. At first 
sight this might be considered the lobed variety of the 
Common Prickly Bern, but the soft and not leathery 
texture of the frond and the length of the stalk show 
that this is a winged variety of the Angular Bern. M. 
Hawkchurch. 
27. Lax A. B. Laxum, This has it pinnae distant from 
each other and alternate. The frond is lance-shaped. The 
leaflets are also distant and lax, with a wedge-shaped base, 
acute, hooked, and spiny at the apex. The upper basal 
leaflet of each pinna is longer than the rest, with a distinct 
auricle. The stalk and mid-stalk is scaly or hairy. M. 
Lyme. 
28. Twice-serrated Lax A. B. Biserrato-laxum, This 
has all the characteristics of the twice-serrated Angular 
Bern with the lax habit of the preceding. M. 
29. Thin A. B. Levidense, A large variety with narrow, 
spiny leaflets, having its auricle broad and stalked, for 
which reason the frond is tripinnate. The frond is from 
two to three feet long. The pinnae are opposite or nearly 
opposite at the base : alternate upwards. M. Hawkchurch. 
30. Thick A. B. Crassum, This is a small plant having 
its leaflets and pinnae broad and short and close together. 
It has also a coarse texture. M. Axminster. 
31. High-stalked A. B. AUiaceum, This has its stalk 
longer than the frond, its leaflets and frond narrow, and the 
whole frond of a peculiarly light and hairy appearance.
