the fall the dull red apple-like fruits make the tree very at- 

 tractive. These miniature apples are about y 2 inch in 

 diameter and contain usually only 2 stones, imbedded in the 

 greenish flesh. 



The tree is of little economic importance except for deco- 

 rative planting. It is found wild from Lake Champlain to 

 Georgia and westward. It is common in the lower and 

 central Hudson Valley. 



The English Hawthorn (Crataegus Oxyacantha) is botan- 

 ically related to the cock-spur thorn and may be distinguished 

 by its jagged leaves, and its usually single stone imbedded in 

 the yellow flesh. It is known in the Hudson Valley only as 

 an escape from cultivation. 



Large-fruited Thorn Crataegus punctata 



The shallower double-toothing of the leaf-margins of this 

 thorn is very distinct from the toothing of the leaves of the 

 cock-spur thorn. The fruits are brick-red and almost always 

 contain 3 or 4 stones, imbedded in the greenish-yellow flesh. 

 The tree attains a height of 25 feet or more. 



It grows from Quebec southward to Georgia and is fairly 

 common along the Hudson Valley. 



The waxy thorn (Crataegus pruinosa) is not a very large 

 tree and is found growing from the Thousand Islands to the 

 southern Appalachians. From the preceding sorts it can be 

 distinguished by its leaf-blades which are broadest towards 

 the base. The fruit is waxy and purple-green in color. It 

 is common in the area covered by this list. 



Round-leaved Thorn Crataegus rotundifolia 



This is credited with a distribution further north than any 

 other North American thorn. It is also widespread, grow- 

 ing as far south as Virginia and westward to Wisconsin. 



It frequently attains a height of 20 feet and forms a beau- 

 tiful round-topped tree. The dark red-brown bark is scaly 

 on the trunk but smooth on the twigs. The prickles are 

 from 1 to 3 inches long and usually curved. The leaf-blades
