462 NATURALIZED PLANTS OP GREAT BRITAIN. [June, 



Hibes Grossularia. " Denizen," Cyb. Doubtful (possibly nativej : 



Doronicum plantagineum. Hesperis matronalis. 



Orobanche ramosa. Doronicum plantagineum. 



Urtica pUuJifera. ^ Naturalized .- 



Arabia turrita. 



Cheiranthus Cheiri. 



Urtica pilulifera. 



Thus, out of the whole number of our disputed natives, but 

 10 obtain De CandoUe's verdict in their favour; there are how- 

 ever a few more which he is inclined to think may be natives 

 of Great Britain, though the English writers do not. These 

 plants are — 



Carum Carui. Tilia grandifolia. 



Peucedanum Ostruthium. Xanthium Strumarium. 



Maianthum bifolium. 7v»Ci*-C. Castanea vesca. 



Anemone ranvmculoides. Ornithogalum umbellatum. 



Doronicum Pardalianches. Leonurus Cardiaca. 

 Tilia europsea. 



The three first have the stronger proofs in their favour. As 

 with all others that have been discussed, their claim to be con- 

 sidered indigenous depends chiefly upon geographical reasons ; 

 they are found upon the neighbouring continent in analogous 

 situations, and sufficiently near to England to admit of their 

 range extending across the Channel. If more scarce with us, 

 this rarity may be owing to their being at the extreme limit of 

 their range ; and it is this very circumstance that presents the 

 greatest obstacle to forming a safe opinion upon the scarcest and 

 most local species of the south of England. 



In such a matter the well-known experience of M. De Candolle 

 entitles his opinion to great respect, and the details given are 

 well worthy of careful study. But it should not be forgotten that 

 \ any one who reasons upon geographical grounds will always be 

 liable to lay greater stress upon the general facts of Continental 

 distribution, than upon the nature of the special localities in 

 which the plants are gathered by the collecting botanist. 



We must now conclude, in the hope that our brief summary 

 may prove of some little service to those of our English botanists 

 who have not access to the original ; but to appreciate the various 

 arguments and the judicious and impartial remarks of M. De 

 Candolle our readers will necessarily refer to the work itself.
