LONGSPiNE HAW. Crataegus macmcantha Loud., C coccinea macracaniha 



Dudley. 



This hawthorn is common in the 

 Champlain valley and occurs in the Con- 

 necticut valley. It may therefore be 

 expected along with the scarlet haw 

 , in most parts of the state. It closely re- 

 y/ sembles the scarlet haw in general appear- 

 ance, but has spines somewhat longer, 

 flower larger and borne in broader, stouter 

 clusters. The fruit is rather smaller, round 

 or compressed longitudinally. It is diffi- 

 cult to distinguish the species by these char- 

 acters alone, however, and it will usually be necessary to appeal to the 

 leaves in its identification. These are shining, thicker and more leathery 

 in texture than those of the scarlet haw and have a wedge-shape base 

 merging into a rather short stout petiole. A comparison of the figures will 

 help make these distinctions clearer.

DOTTED HAW (SPREADING THORN, DOTTED FRUITED THORN ). Crataegus punctata 



Jacq. 



The dotted haw is a curious looking tree 

 with stout branches spreading nearly at right 

 angles to the trunk and forming a broad flat or 

 terraced head. This character is more clearly 

 seen in the older trees and when viewed from 

 a short distance. Its identification may be 

 made more certain by comparing the form of 

 the leaves with the accompanying figure and 

 also by noting the fruit characters. The fruits 

 are larger than those of the scarlet haw, some- 

 times nearly an inch in diameter, turning 

 dull red or yellow in autumn and marked 

 with whitish spots. This last character has 

 given name to the species. The dotted haw 

 thrives best on rocky upland pastures and is not uncommon throughout 

 the state.
