MOSSES AND HEPATICS OF SKIPWITH COMMON, 
S.E. YORKSHIRE. 
WILLIAM INGHAM, B.A., 
Organising Inspector of Schools, 47, Haxby Road, York. 
I HAVE lately eirhipleted my List of the Distribution of British 
Mosses in the five Vice- Seentes of Yorkshire, and in the 
County of Durham. 
As the list is a very extensive one, and far too large for ‘ The 
Naturalist,’ I propose to select certain well-known spots in 
Yorkshire and Durham, and give Lists of Mosses and Hepatics 
I have found there. 
The present list deals with Skipwith Common only, and 
contains the names of 67 Mosses and 14 Hepatics, which I have 
_ found and determined during several visits to the Common in 
1897 and 1 sage 
I am much indebted to Mr. H. N. Dixon, M.A., F.L.S., 
for kindly sovivias all doubtful Mosses in the List, except 
four of the Hypnacez, viz., the two varieties of Hyp. aduncum 
and the last two varieties oe HHypnum fiurtans, which have been 
sed verified by Dr. Braithwaite. 
m also much indebted to Mr. M. B. Slater, F.L.S., of 
Silt for kindly verifying the Hepatics. 
he nomenclature of the Moss List is that of the ‘ Handbook 
Catalogue of British Mosses,’ by Mr. H. N. Dixon, and the 
nomenclature of the Hepatic List is that of the ‘Moss Exchange © 
Club Catalogue of British Hepaticz,’ compiled by Rev. C. H. 
Waddell, B.D. 
It may be interesting to note that the Siliceous soil of this 
Common, and the abundance of water, are peculiarly adapted to 
_ the growth of the larger Hypna, which thrive here most 
— luxuriantly. .
