24. ROSACEA. 331 



Native. Septal, &c. Primus spinosa is a fi-equent 

 shrub in old hedge-rows and on the common wastes of 

 England ; and is probably to be found in every county ex- 

 cept the North Isles. It is omitted, however, from Mr. 

 Gutch's list of Swansea plants ; though a shrub wliich is 

 so frequent in the Peninsula and North Wales cannot be 

 supposed absent from South Wales. P. insititia is much 

 less common, though still pretty frequent. But P. domes- 

 tica seems only to occur as a descendant of the varieties in 

 cultivation. The truly wild forms appear to pass into each 

 other so gradually and completely, that distinctive charac- 

 ters cannot be appUed to them. Dr. Bromfield writes of 

 P. domestica — " By this name I call the largest of a series 

 of inseparably linked forms, ascending from the common 

 sloe."
