TUNBRIDGE FILMY FERN, [natural size). 
Hymenophyllum tunbridgense, Smith. 
The little moss-like ferns which constitute the genus Hyme- 
nophyllum are found growing on the surface of rocks and stones, 
in moist and shady situations. Unfortunately in my endeavours 
to draw up a summary of habitats, I can derive but little assis- 
tance from the ‘ Botanist’s Guide,’ since its learned authors do 
not distinguish between the species, but treat them both as one ; 
and, therefore, a doubt must attach to the species found in the 
localities which I have quoted from that work. The other Eng- 
lish and Welch habitats of H. tunhridgense have been supplied 
by correspondents on whom I can confidently rely. 
Cornwall. — Mr. Babington and Mr. Borrer inform me they 
have found this species at Rough tor, near Camelford ; Miss 
Warren in two places in a wood near Penryn ; and Mr. Peirson 
at College wood, near Penryn. 
Cheshire. — On mossy rocks near Croyden brook, the east- 
ern extremity of Cheshire, and on the hills from Macclesfield 
to Buxton in similar situations : Mr. Bradbury.” — Botanisfs
