BOTANY 



A LIST OF THE FLOWERING PLANTS OF DURHAM 



OBSERVATIONS 



The order and nomenclature of the following list are those of 

 Sir J. D. Hooker's Student's flora of the British Islands, 3rd Edition, 

 1884. The numbers after the specific names refer to the zones of 

 altitude. The authorities made use of in this account are the admirable 

 Flora of Northumberland and Durham, by Baker and Tate, 1 and Winch's 

 Essay on the Geographical Distribution of Plants through the counties of 

 Northumberland, Cumberland and Durham (1825), together with the 

 author's own observations. The list of flowering plants and ferns is that 

 of Baker's Flora ; the species marked * are added from a list by Mr. J. 

 A. Wheldon. Mr. W. Ingham, B.A., has been kind enough to contri- 

 bute the sections on Mosses and Liverworts, and the Rev. W. Johnson 

 that on the Lichens.
