 dm. in diameter, covered with dull gray bark separating near their 

 base into small scales, or rarely arborescent with spreading branches, 

 and slender only slightly zigzag branchlets, dark orange-green and 

 marked by many large pale lenticels when they first appear, light 

 orange-brown and lustrous at the end of their first season, and pale 

 gray-brown the following year, and armed with many slender nearly

This species is closely related to Crataegus Peoriensis, Sargent, 

 of central and northern Illinois, with leaves of the same form and the 

 peculiar orange colored branchlets of the first year. It differs from it 

 chiefly in its fewer-flowered corymbs, coarsely and constantly serrate 

 calyx-lobes much more villose on the inner surface, in its usually more 

 numerous stamens, in its fewer styles, small fruits and larger nutlets.
