LIST OF MOSSES OCCUREING NEAR WETHERBY, 



IN THE VICE-COUNTY OF MID-WEST TOKK, 



OBSERVED BY J. S. ^YESLEY, M.B., Lond. 



The following list includes no species but what occur within four 

 miles from Wetherby. The country about Wetherby is gently 

 undulated, well wooded, and has the two rivers Nidd and Wharfe 

 running through it. The underlying rocks are mainly magnesian 

 limestone and the sandstone known as Plumpton grit. Fine perpen- 

 dicular cliffs of limestone margin the Wharfe on its south side below 

 Wetherby. The disused quarries north and west of Wetherby have 

 hitherto produced the greatest number of good species. 



The chief value of this list, in the opinion of Mr. Lees, will 

 probably be found to depend not so much on the great rarity of any 

 of the species given, nor upon any great interest attaching to the 

 several localities, as upon the fact that the records are unusually 

 reliable — nearly, if not all, having been verified by such competent 

 authorities as Messrs. Boswell, Braithwaite, and Fergusson, through 

 specimens submitted to them for verification. 



Further, after four seasons' careful examination of a district 

 thoroughly familiar to me, the list may be regarded as almost com- 

 plete for the limited area of which it treats, with the exception that 

 some of the smaller mosses probably growing here have not yet been 

 detected. 



I may add that the claim to inclusion in the W. R. flora of the 

 following species, viz., Pottia intermedia^ Turn. ; Bidymodon cylindri- 

 cuSf Bruch. ; Fissidens viridulus, Wils. Thiddium ahietinum, L. ; and 

 Hypunm Sendtneri, Schpr., rests solely on Wetherby district localities.
