THE FERN FAMILIES OF BRITAIN. 
The characters of both the parents are distinctly conjoined, 
the result being a slightly expanded form of cornubiense, 
crested at all tips a la hifido-cristatum. The piecemeal 
reversion peculiar to the former is maintained, but the 
usually normal parts take the character of the latter, so 
that the joint parentage, it will be seen, is demonstrated 
beyond the shadow of a doubt. 
P. V. glomeratiun (clustered), Mullins. This is an oddity, 
every frond and division branching repeatedly anyhow, no 
two alike. 
P. V. grandiceps (large-crested), Fox (7). The finest 
crested form yet found. Immense, wide, curly crests at all 
terminals. Extremely handsome. 
P. V. multifido-cristatum (much-cleft, crested). Syn. 
grandiceps (Parker) (6). End of frond very much branched, 
with minute, curly crests at tips of all divisions, forming a 
huge, bunchy tassel at the expense of the pinnae, which are 
comparatively few. 
P. V. omnilacerum (wholly torn) (13). One of the finest 
and robustest forms known, when it can be got to develop 
properly; pinnae^ divided into very long, toothed divisions, 
overlapping densely. 
P. V. parvissinmm (very small) (11). Introduced into 
our plate to exemplify range of size, its neighbour there (13) 
attaining 24in., while this, which has been found several 
times, is a miniature reproduction of the common, under lin. 
when full grown. 
P. V, pulcherrimum (very beautiful) (8). A beautifully- 
divided form, resembling camhricum in general outline, but 
without its delicacy of texture, the fronds being of the 
normal leathery character, and freely fertile; the ultimate 
divisions are also not so finely saw-toothed. Wild find. 
P. V. plumosum (feathery), Hadwin. Another very fine 
plumose form, and sufficiently distinct. 
P. V. ramosum (branched), Hillman (3). A robust form, 
in which the fronds all branch from below upwards repeatedly, 
forming frequently wide, flat crests, when the forking is 
carried far enough.
