66 5. R. PLICATUS. 



that our present plant is the typical R. fruticosus (Linn.), 

 although he certainly, as stated by Mr Bon-er, included 

 several other species under that name, especially in his 

 later works. "VYahlberg {Fl. Goth. 56) points out that the 

 R. maritimus of the Skanska Resa (272) is our R. plicatus ; 

 and Linnaeus quotes that plant as his R. fruticosus in the 

 Flora Suecica. Wahlberg found it in the place mentioned 

 by Linnaeus. It was in the 2nd edition of the Flora Sue- 

 cica that the confusion commenced, from Linnaeus there 

 adding some remarks which do not apply to R. plicatus^ but 

 to his R. 7naximus fructu nigra which is the R. corylifolius 

 (Sm.). It seems to me that those authors act wisely who 

 drop the name R. fruticosus as being only a cause of am- 

 biguity. Specimens received from Sweden under the name 

 of R. fruticosus are exactly our and the German R. plicatus. 



If we are to judge from French specimens named R. 

 fruticosus V. intermedins by Holandre the R. Godronii (Lee. 

 et Lam.) is a state of R. plicatus: but if Godron's descrip- 

 tion is our guide we must place R. Godronii close to R. 

 corylifolius. 



The late Mr Bicheno, who paid much attention to the 

 brambles, was satisfied that R. plicatus is distinct, for he 

 said of his R. ericetorum from Snelsmore that it is " deci- 

 dedly a good species." He never published his denomination 

 of the plant, but specimens named by him are unques- 

 tionably R. plicatus.
