aspect proper to the species in its normal state are quite destroyed. 
In all other respects this variety resembles the normal plant. It has 
been found—near Tunbridge Wells, Kent, G. B. Wollaston. Car- 
narvonshire: Llanberis, Rev. J. M. Chanter. [Plate XXXI.] 
2. caudata (M.). This has a good deal of the normal character, 
but it differs conspicuously from the common states of the plant, in 
having the apex of its fronds and of the pinne narrowed and drawn 
out to a considerable length, so that the fronds become elongately 
lanceolate, and the pinnæ caudate. It was found at Windermere 
by Mr. Clowes, and has been cultivated by him without changing 
its character for several years. The apex of the frond is fre- 
quently, but not constantly, divided in a trifid manner. 
3. abrupta (M.). This form, the constancy of which has not 
been sufficiently tested, has narrow fronds; the pinn® are short, 
bluntish, often bifidly and very obtusely dilated at the end, the 
pinnules interrupted and irregular in size. It was found by Mr. 
C. Jackson, near Barnstaple. 
4. crispa (M.). This form has the pinnules undulated or wavy, 
so that the frond acquires a crispy appearance; it is otherwise 
normal. It was found by Dr. Balfour, on the Clova mountains. 
5. cristata (M.). This is a beautiful variety, analogous to the 
 eristate forms of Filie-mas and Filiw-feemina, and most nearly 
resembling Athyrium Filiz-femina, var. corymbiferum in. its confor- 
mation. The fronds are rather small, and corymbosely branched 
towards their apex, the branches being dilated into broad cristate 
tassels ; the apices of the pinn® also are multifid-erisped, though 
in a less degree than the apex of the frond itself. It was found in 
Monmouthshire, by Mr. T. H. Thomas.
