366 THE FERN WORLD 
It has also been found in Cashmere and Siberia. In the 
British Islands, as we have seen, its recorded habitats are 
few in number. In Eng'land it has been found at Matlock, 
in Derbyshire ; in the Swanage Cave in the Isle of Purbeck, 
in Dorsetshire ; in the neighbourhood of Petersfield, in 
Hampshire ; also in Whamcliffe Wood, Yorkshire. Some 
specimens were also found on an old garden wall at Tooting, 
in Surrey, but the wall appears to have been cleaned, and the 
Ferns all destroyed. It is also stated to have been found 
near Alnwick Castle, Northumberland, and by its first dis- 
coverer in Britain— Mr. Hudson — at Wybourn, in Westmore- 
land. In Wales it has been found between Tan-y-Bwlch 
and Tremadoc, in Caernarvonshire ; and in Scotland upon 
some shady rocks near Stonehaven, in Kincardineshire. One 
habitat, Cavehill, near Belfast, has also been named in 
Ireland. 
Culture. — The same soil under cultivation should be pro- 
vided for this little Fern as for Aspleninm lanceolatum, 
namely, leaf-mould and sandy loam, with pieces of sandstone 
or soft broken brick interspersed through the compost. It 
will grow readily under the protection of glass, and in pots, 
if the latter be kept in a greenhouse. Under the influence 
of heat and moisture it will attain its maximum length 
o 
of a foot, but especial care must be taken to keep it well 
drained.
