Mr. Winch finds this species on the sands of the sea-shore in 

 Northumberland, mixed with R. spinosissima : it is also said to 

 have been brought from Scotland. The ripe fruit I have never 

 seen. 



The resemblance of R. rubella to R. spinosissima may perhaps 

 have occasioned it to have been so long overlooked ; though the 

 stems and branches covered with setae, intermixed with a very few 

 slender aculei, sufficiently distinguish it. The simple serratures 

 of the leaflets will not suffer it to be confounded with R. involuta 

 or R. Doniatia. 



The specimen of R. pimpinellifolia in the Linnaean Herbarium 

 considerably resembles this species ; but it is not sufficiently 

 perfect to enable me to pronounce with confidence : I have there- 

 fore preserved the name given to it in English Botany. Perhaps 

 some other authors may also have intended this plant by R.pim- 

 pinelUfolia ; but I have not been able to unravel their synonyms 

 from those of R. spinosissima.
