A fine handsome vigorous American thorn, forming a 

 tree with a spreading head, and having firm dark green 

 leaves, amongst which are intermixed stout curved spines 

 of unusual length. I have seen them as much as four inches 

 and a half long. It flowers in May, and produces an abun- 

 dance of its deep vermilion-red haws in the autumn. 



No writer upon the wild trees of North America notices 

 this remarkable plant; it is therefore in all probability of 

 garden origin ; indeed I entertain no doubt of its being a 

 mere variety of C. glandulosa, possibly of hybrid extraction, 

 between that species and C. crus-galli.
