Differs from the preceding variety in having broader and shorter leaves, a 



more compact and fastigiate habit of growth, and rather more thorns on the

 5. Fruit black. (Dec. Prod.) A low tree. Hungary. Height 15ft. to 

 20ft., throwing up numerous suckers from its widely spreading roots, which 

 soon cover the ground with a forest of bushes. In England, where it is 

 generally propagated by grafting on the common thorn, it forms a very 

 handsome, upright, somewhat fastigiate tree, from 20 ft. to 30 ft. high, put- 

 ting forth its leaves, in mild seasons, in February or March. Introduced in 

 1819. Flowers white; April and May. Fruit black; ripe in July and 

 August.
