98 THE BRITISH FERNS, 
auricled at the truncate anterior base, the lower ones deflexed, 
trapeziform, the rest often imbricated, and usually crenately 
toothed. It has been found in— Yorkshire: Cloughton Bay, Scar- 
borough, A. Clapham. Devonshire: Saleombe, near Kingsbridge, 
T. G. Carter ; Hance's Cove, Torquay, C. Smith. Cornwall: St. 
Just, G. Maw. Down: Newcastle, Macreight. 
2. pulchrum (M.). This is a small form approaching ramosum (5) 
in appearance, but is a less marked variety, though a neat and 
pretty plant. The fronds are small, varying from about four to six 
or eight inches high; the pinne short, oblong obtuse, truncate and 
slightly auricled in front, cuneate behind, the margin doubly crenate, 
and in the best examples sub-lobate from the depth of the primary 
erenatures. It is its dwarfishness, together with the lobate character 
it assumes, which gives its distinctive features to the variety. It was 
found on the rocky banks of the Dart, near Totnes, by Mr. C. Scott.

3. cuneatum (M.). This form is peculiar from the absence of the 
truncate aurieuliform projection usual at the anterior base of the 
pinne, the base being acutely but obliquely wedge-shaped. The 
pinne are oblong, obtuse, about an inch long, less coriaceous than 
usual, and cut along the margins with deep sharp uneven serratures, 
so as to become unequally biserrate. It was found by Dr. Allchin at 
Black Head, Clare, Ireland; but we are not aware that its constancy 
has been tested by cultivation. 
4. crenatum (M.). This form is remarkable for its short, obtuse, 
oblique, trapeziform pinns, and for the small even deep roundish 
crenatures, by which it is notched around the margin. In the general 
outline of its pinne, it resembles ramosum, but the toothing of the 
margin is altogether different. The plant was originally found in 
Hulme stone quarry, Winwick, near Warrington, Lancashire, and 
specimens have been communicated by Mr. T. G. Rylands. [Plate 
LXXIII bis, A.] 
5. ramosum (Woll.). This is a very marked variety. One of its 
chief peculiarities is that the fronds are branched, which branching 
takes place sometimes in the rachis, but more frequently at the base 
of the stipes, so that the fronds become united in pairs, the junction 
often taking place before they separate from the caudex, so that
