HYMENOPHYH.UM WILSONI. 
139 
In Wales on Snowdon, near Llanberris Pass, and on 
the adjacent mountains, especially near Twll Du, and 
on high rocks about Nant Phrancon, and on rocks near 
the Rbydol at a plank over a gulf of the river Pont 
Bren. In Scotland at Finlarig Burn, near Killin, 
Perthshire, and in Argyleshire. In Ireland at Killaruey, 
Shannafolia Mountains, Kerry Mountains, and Con¬ 
nemara.—( Francis's British Ferns.) 
Mr. Reeve, writing to us of its culture, says, “ The 
Hymenophyllum Wilsoni is very much like the Tun 
hridgense, but of larger growth and stronger habit. 
Each of the species thrives remarkably well under the 
treatment directed for the latter; but H. Wilsoni is not 
adapted for artificial rockwork, as a glass of any kind 
continually kept upon such a structure looks very 
unnatural; and as it could not be cultivated thereon 
with any certain success without a glass covering of 
some kind, it had better be withheld from rockwork 
altogether. Each of the species thrives remarkably well 
in the stove or greenhouse, pit or close frame; but 
whichever situation may be chosen, the plants must bo 
protected from sunshine. They are readily increased 
by division, by carefully arranging the small pieces on 
the surface of the compost directed for U. Tunbridgense. 
By keeping the whole close, moist, and warm for a short 
time, the plants will very soon establish tnemselves."
