THP: blackthorn (Prunus spinosa). 



There are many \'arieties of the Sloe, such as the Bullace tree 

 and the Wild Plum. The chief distinction between these and the 

 Sloe lies in the simultaneous appearance of their leaves and Hovvers. 

 The leaves also differ in being downy, the twigs are devoid of spikes, 

 and the flower and truit larger.
