2l6 THE FLORA OF HALIFAX. 



Very little work in this branch has been done during the 

 last two decades. Mr. J. Needham and the writer have 

 collected a few incidentally from time to time. These have 

 been submitted for identification to Mr. Thos. Hebden, of 

 Cullingworth, a most painstaking and reliable authority. We 

 here tender him our thanks for his great kindness. 



The classification is that of the Rev. W. A. Leighton's 

 Lichen Flora of Great Britain and the Channel Islands, 3rd 

 Ed., 1879. Only such synonyms are given as are necessary to 

 identify the present terminology with that employed in Bolton's 

 Catalogue and Leyland's Herbarium. C. C.
