ORNAMENTAL VARIETIES. 
COMMON ENGLISH SLOE, OR BLACKTHORN. 
Prunus spinosa.—This being an ornamental tree in shrubby 
plantations, we find that the branches are more thorny than the 
common damson, and the fruit is nearly round, quite black, but 
covered with a thick blue bloom. In spring the tree is a perfect 
cloud of white bloom.
