Remarks) within -which they lie, as, in the case of A. Pulsa- 

 tilla, (1) Cambridge, (2)Royston, and (5)Burwell. In record- 

 ing the localities, the author is responsible for all those which 

 are followed by a full stop. Those names of places followed 

 by a semicolon (;) were received from the correspondents 

 whose initials succeed that stop; as, "Linton; W. H. C," 

 shews that the plant was found at Linton by the Rev. W. 

 H. Coleman, but that the author has not himself observed 

 it there nor seen a specimen from thence ; had Mr Coleman 

 shewn a specimen to him, a note of admiration ( ! ) would 

 have followed the word Linton. When several localities 

 were communicated by the same correspondent they are 

 separated from each other by semicolons, and the whole 

 series followed by his initials. Those localities which rest 

 solely upon the authority of the older botanists are printed 

 in Italics, and followed by the abbreviated name of the 

 author on whose authority they rest. 



In order to shew the history of each plant as a native of 

 this county, the earliest work in which it is known to have 

 been recorded as such stands first among the synonyms; it 

 is often that of Ray, but sometimes an earlier writer; occa- 

 sionally also it is an author of later date than Relhan, such 

 as Prof. Henslow, in one of the editions of his Catalogue of 

 British Plants. 



The following marks are used in this book, and require 

 explanations. The first three of them always precede the 

 name of the plant. They refer solely to the condition of 

 the plant in Cambridgeshire. 



* Certainly introduced, but naturalized. 



t Possibly introduced, but now having the appearance of 

 being a true native.
