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 downy 

 leaves. The latter are generally more or less blotched with 

 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 be a native of Asia Minor ; I have not seen 

 any wild specimens. 



Mr. Loudon has rightly reduced the plant to its true 

 type ; it is not in fact very different from the black-fruited 

 hawthorn sometimes found wild in the woods of Great 

 Britain. Of course it is not to be confounded witli C. nigra, 

 a genuine and very distinct species.
