The names of the Plants indigenous to the district are printed in Roman 

 LETTERS; of naturalized species in italics; and of plants cultivated for 

 their utility in fields and plantations, the name is in the Alltic[lie letter. 

 Stragglers of uncertain permanency, and notices of extirpated species, are 

 printed in a smaller character and thrown into notes. To each of these 

 classes there is besides a distinct set of numerals. Some species which 

 have been inti'oduced into former catalogues of our Flora, from inadvert- 

 ency or error, are omitted without notice. 



To the " Habitats " in Berwickshire and in the Liberties of Berwick 

 a B. is prefixed ; a D. to those in North Durham ; an N. to those in North- 

 umberland ; and an R. to those in the county of Roxburgh. — When no 

 authority is given for the " habitat," it is to be understood that the plant 

 has been gathered there at a meeting of the Berwickshire NaturaUsts' Club. 

 In many instances the authority for the station is given, although the Club 

 may have subsequently verified the discovery. 



The scientific nomenclature of the species is derived from the " English 

 Flora" of Sir James E. Smith. When they differ, the names used in Mr. 

 Babington's Manual and in the " British Flora," as edited by Professor 

 Aruott, are also given. 



The provincial names of the Plants are printed in the <f^VO (rn^ll^l^ or 

 ^lack Utttr. Great pains have been taken to collect these, which, it 

 must be borne in mind, are often known to a few of the most obsei-vant 

 only. They are sometimes too veiy local even in our limited district. 



The notices of the vulgar customs, virtues and uses connected with the 

 plants, are also provincial, except when the contrary is stated. These 

 notices have been derived principally from the communications of Mr. 

 James Hardy, whose assistance in every jiart of this work I am anxious to 

 acknowledge.
