BRITISH FERNS 

Fig. 280, 5, v. crispum fimo. cristatum. 
С. к. CRISTATUM (Fig. 280), of Stansfield and Cropper, and 
С. DRUMMONDA, found Бу Miss Drummond at Falmouth, аге 
both fringed and tasselled, the latter ranking as one of the most 
remarkable, having two sorts of fronds, one very long, narrow, and 
frilled, with plain edges and very broad, branched crests, and the 
other on like lines, but beautifully fringed, the tips of the fringes, 
if layered, yielding plants Бу apospory (see page 17). 
С. D. suPERBUM.—Has по plain-edged fronds, all are fringed. 
С. D. GRANDICEPS.—Raised by Mr. H. Bolton, of Carnforth; has 
extra heavy tassels. 
С. FERTILE.—Varieties of the frilled type have been found which 
are partly fertile ; as seedlings they are fully equal to the barren 
forms, but when they begin to bear spores, the frill is defective, the 
frond apparently being incapable of bearing spores and completing 
the frill. By virtue of this fertility, crosses have been effected 
with good results,
