FOUR NEW YORKSHIRE MOSSES; 
WITH FURTHER LOCALITIES AND NEW RECORDS 
FOR THE MOSS-FLORA OF UPPER SWALEDALE AND 
NORTH YORKSHIRE GENERALLY. 
RICHARD BARNES, 
The Gardens, Saltburn-by-the-Sea. 
THE discovery in an entirely new locality of four rare and elegant 
species of Bryum, viz., Bryum Warneum Bland, Br. lacustre Brid., 
Br. Marratii Wils., and Br. calophyllum R. Br., will be, doubtless, of 
some interest to working bryologists, since, so far as their distribu- 
tion in Britain is concerned, they are confined to few stations 
indeed, and to which, apparently, no recent additions have been 
made; and, moreover, their occurrence in the marshes wager 
the estuary of the Tees furnishes respectively, to the bes 
knowledge, new records for the Moss-flora of Yorkshire sichiy, 
while Br. Warneum and Br. Marratii are new to the East Coast 
of England. Tod Point is situated somewhat west of Coatham, 
and from this portion of the coast the estuary of the Tees is bounded 
for a considerable distance by a broad tract of sandy, marshy ground 
usually | known as Coatham Marshes. ‘The physical character 
Southport and the two Scottish stations, viz. ., Tents Muir and the 
Sands of Barrie. A careful investigation, however, was not made 
until the latter part of 1891, when the pleasure was afforded me of 
meeting with the rare species mentioned herein. 
In the ‘ Phytologist,’ for December 1858, p. 638-643, and 
April 1859, p. 104-107, there are excellent accounts by the late 
Dr. J. B. Wood, regarding, among other rarities, the occurrence of 
Br. Warneum, Br. Marratii, and Br. calophyllum on the sands 
at Southport, in which locality, I believe, they were first discovered 
as new to the Moss-flora of Britain. Many interesting incidents are 
given as to the earlier gatherings of the above-named plants, which 
render the two papers well worth perusing. 
My sincere thanks are hereby tendered to Dr. Braithwaite, F.L.S., 
for his kind assistance in examining and verifying the species 
enumerated in this list. 
The sub-genus Cladodium, to which Schimper refers the present 
four species, depends on the more or less imperfect structure of the 
inner peristome as its chief distinguishing characteristic. 
May 1892.
