 from all the other British species b}' its trailing habit. Some of the vars. 

 so closely resemble tiie true Ayrshire Rose, (7i, capreolata,NeillBud Bon,) 

 that I know not where to draw the line of separation. Mr Sabine, how- 

 ever, regards that plant as a deciduous var. of M. sempervirens, and 

 points out the shining leaves, paler, but without glaucescencc, on the 

 under-side, and the hairy stigmas, with some other minute diti'erences, as 

 distinguishing it from R. arvensis.
