This handsome tree is most conveniently placed in the F/ade//atae group 
with Crataegus Holmesiana Ashe. From that species it differs in its larger 
darker green and more scabrous mature leaves, in its more lax villose 
corymbs, larger flowers on longer pedicels, with coarsely glandular-serrate 
calyx-lobes, more numerous stamens and styles, and in its larger and later- 
ripening fruit.

or rarely oval, acute or acuminate, gradually narrowed and full and 
rounded or broadly cuneate at the base, deeply divided above the 
middle into three or four pairs of broad acute or acuminate lobes,
