Crataegus palliata Sarg. This small tree also belongs to the Crus-galli 

 group, and type was collected at Fulton. It grows in fertile open woods 

 and on rich hillsides. 



Crataegus triumphalis Sarg. A small tree of the Crus-galli group, 

 growing in open upland woods. The type locality is Fulton. 



Crategus sordida Sarg. This is a small tree of the Punctatae group origin- 

 ally described from southern Missouri. Two trees have been found near 

 Fulton, growing in a thicket on the edge of the upland woods, which 

 perhaps belong to this species. 



Crataegus fastosa Sarg. A small tree of the Punctatae group growing in 

 low woods. The type locality is Fulton. 



Crataegus amicalis Sarg. A species originally described from Fulton, 

 belonging to the Virides group. It is a small tree growing in open upland 

 woods. 



Crataegus micrantha Sarg. A small slender tree of the Virides group, 

 growing in low woods near Fulton, from which locality it was originally 

 described. 



Crataegus blanda Sarg. A small round-topped tree of the Virides group 

 rather abundant in upland woods and on gravelly ridges in the Fulton 

 region. It differs from most of the other species of this group in its rather 

 thick dark bark. This species has also been found in Alabama, Louisiana 

 and Texas. 



Crataegus velutina Sarg. This species closely resembles C. viridis L. 

 except in its more or less densely pubescent leaves, branchlets and in- 

 florescence. It is rather common about Fulton which is the type locality 

 and it has also been found in eastern Texas. 



Crataegus enucleata Sarg. A small tree of upland woods. Type ma- 

 terial of this species was collected at Fulton. It belongs to the Virides 

 group. 



Crataegus lacera Sarg. A slender tree growing in rich soil in open situ- 

 ations. It is one of the most interesting species described from the 

 Fulton region, being very distinct in characters and of dubious affinities. 

 It was doubtfully referred to the Tenuifoliae group by Professor Sargent, 

 but it differs markedly from other members of that section, which has no 

 other representative known west of the Mississippi River. It may re- 

 present a distinct group of this large genus. 



Crataegus viridis L. A very common species growing both in low woods 

 and in the flat uplands. It is one of the largest of all the Haws, sometimes 

 becoming a tree 10 meters or more in height. 



Crataegus induta Sarg. This is a small tree of the Molles group growing 

 in upland woods near Fulton, which is the type locality. 



Crataegus invisa Sarg. This species, also belonging to the Molles groupj 

 is rather abundant in rich low woods throughout the Fulton region, where 

 it was first found. It has also been collected at San Augustine, in eastern 

 Texas.
