This supposed species is clearly nothing more than a 
variety of the common hawthorn; from which in fact it 
differs in little, except its oval black haws and down 
“leaves. The latter are generally more or less blotched wit 
brown in the autumn; and the cymes of haws are more 
compact than those of the common Cr. oxyacantha. The late 
M. Bosc, the author of the name, was one of those species- 
makers, who do serious injury to science by the number of 
errors they crowd into it. 
It is said to bea native of Asia Minor; I have not seen 
any wild specimens. = 
Mr. Loudon has rightl reduced the plant to its. true 
type; it is not in "den fferent from the black-fruited 
hawthorn sometimes found wild in the woods of Great 
Britain. Of course it is not to be confounded with C. nigra, 
a genuine and very distinct species.
