1858.] NATURALIZED PLANTS OF GREAT BRITAIN. 459 



belonging to these sections will be better reserved for the next 

 part of our subject. 



To obtain as clear a view as possible of our " suspected " 

 species^ those printed in italics have been selected from the 

 ' London Catalogue of British Plants ' (5th edition) ; from Ba- 

 bington^s ' Manual ' (4th edition) those to which a '^ or f is 

 prefixed; and from Hooker and Arnott's 'British Flora' the 

 "starred'' plants. 



On comparing together these lists the plants readily arrange 

 themselves under three classes, 



1. Species with two authors out of three in favour of their 

 being indigenous to Britain. 



2. Species with only one author in their favour. 



3. Species rejected by all three. 



We have only space to enumerate the two former^ with the 

 omission of a few extinct alpine and critical plants. 



1 . Admitted to pass as natives both in the London Catalogue 

 and in Babington's ' Manual/ but " starred " in the ' British 

 Flora :'^-—

* Though Ireland is excluded fi'om De Candolle's treatise, Sist/rinchium anceps 

 might be placed here. This plant is beheved to be a very dubious native in the 

 single Irish locahty ; and, as Woodford is 20 miles from the coast, the supposition 

 of any transport across the Atlantic becomes inadmissible. Most of the " Denizens" 

 of ' Cybele Britannica ' are printed in the same type as Natives in the Loudon 

 Catalogue.
