ROSACE.E. 231 



"Mr. T?al<ov thinks tlic British plant is probably llic H. systyla 

 of Bastard, which has been doubted both by ^Ir. Borrcr and Mr. 

 AVoods. I am strongly inclined to agi-ee with ]\Ir. Bcntham in 

 considering this a form of 11. canina, to which opinion Mr. II. C. 

 AVatson likewise inclines. It appears to have no connection with 

 K. arveusis, except in the purely artificial character of the united 

 styles. 



Columnar-styled Dog-rose. 



French, Hosier d, Cotonne en massue. 



Tlie specific name of this Rose comes from the words <tii>' {syn), toj^ether, and oruXoc 

 (stylos), a column, in reference to the styles being connected. All the Roses, known 

 in our gardens as Banksian Roses, belong to the same division. They are named after 

 Lady Banks, and are natives of China. Generally they grow well in the open air 

 against a sheltered wall, and succeed better in a dry situation than in a moist one. 

 The seeds are not perfected in this country, but are in Spain and Italy. The common 

 British species difl'ers very little to the ordinary observer from the ordinary Wild 

 Rose.
