124 THE BRITISH FERNS. 
3. cuneatum (M.). This form is often scarcely more than pinnate, 
with long narrow pinn which are cuneate below, and truncate or 
more or less abrupt and sublobate above, with numerous fine some- 
times longish teeth. When very vigorously grown, the basal pinne 
divide into three pinnules, of which the lowest is often distinct, 
the others more or less combined, but they retain their peculiar 
elongate cuneate form. This variety in its less divided state has 
sometimes been mistaken for Asplenium germanicum, but the texture 
is stouter than in that plant, the parts are broader, and the apical 
teeth are smaller or narrower and comparatively equal. The plant 
has been obtained from Stenton Rock, near Dunkeld, Perthshire, 
by several botanists. [Plate LXXIX A.] 
4. spathulatum (M.). This is a large and vigorous form, remark- 
able for having the base of its pinnules narrowed downwards, so 
that, the apex being bluntish, they become spathulate. The apex is 
sometimes rounded off, but it is more usually bluntly angular, the 
pinnule thus acquiring something of an elongated rhomboidal 
outline. It is probably a not uncommon form: we have seen it 
from—Kent: Town Malling, Dr. Allchin. Devonshire : Marwood, 
Rev. F. Mules. Yorkshire: Settle, 4. Clapham. Perthshire: Dun- 
keld, Rev. R. Taylor. Fife, C. Howie. 
5. elatum (Lang). This is a tall but slender form, bipinnate or 
sometimes almost tripinnate, but chiefly remarkable for the small 
size, and narrowly wedge-shaped form of the pinnules, which are. 
usually bluntish and toothed at the apex, but sometimes truncate, 
and occasionally subtrilobate. We have seen this form from— 
Ireland : Ennis, Dr. Alichin ; Mitchelstown Castle, near Cork, P. F. 
Keir; near Athenry, Galway, R. Barrington; Keswick, Cumberland, 
Miss Wright. The same appears to have been found by Mr. Wilson 
in Dovedale. [Plate LXXIX D.] 
6. dissectum (Woll.). This very elegant form has the pinnules 
elongated and deeply incised. It is an unusual state of the species, 
and has been found by Mr. Wollaston in Devonshire, and by Dr. 
Kinahan in the county of Louth, Ireland. 
7. unilaterale (M.). This curious variety is remarkable for its 
one-sided growth, developing a normal pinna on one side of the 
frond, while the rest is confused, with the rachis often excurrent and
