ULMACEAE 145 



as commonly as U. Americana is in the North. The wood has 

 about the same properties. 



Grows in bottom-lands and flatwoods, and on banks of rivers 

 and creeks, especially in clayey and calcareous soils. Occasionally 

 comes up spontaneously in vacant lots and along city streets, near 

 where it has been planted. 



lA. Lauderdale, Colbert and Limestone Counties. 



IB. Common, especially in flatwoods, making about 2% of the forest. 



IC. Morgan County. 



2B. Fayette, Walker, Jefferson and Tuscaloosa Counties. 



3. Frequent; about 1% of the forest. 



5. Cliffs on Coosa River, Elmore County. (Doubtless occurs in most 

 of the other counties, but I never happened to make note of it.) 



6A. Franklin, Tuscaloosa and Bibb Counties. 



6C. Perry, Dallas, Autauga and Elmore Counties. 



7, 8. Frequent: about 1%. 



9. Wilcox County. 



low. Frequent; about 1%. 



11. Choctaw and Monroe Counties. 



13. Rather rare. Conecuh River swamp, Escambia County. Stock- 

 ton (Mohr). 



Ulmus fulva, Mx. {U. piibesccns, Walt.?) Slippery elm. 



A small or medium-sized tree, with very rough leaves, and 

 flowers in small dense clusters in early spring, ripening seeds 

 about the time the leaves come out, as in the two preceding species. 

 This species would make a good shade tree, and its wood is much 

 like that of other elms, but it is chiefly noted for its mucilaginous 

 inner bark, which is a well-known drug. In some localities it is 

 hard to find a tree from which some of the bark has not been 

 peeled at some time or other ; and for that reason it is not often 

 planted in streets and parks. It is said (in Autauga County) to 

 make good fence-posts, but it is too rare to be used much for that 

 purpose. 



Chiefly confined to very rich woods, especially in calcareous 

 soils, much like the black walnut, with which it sometimes asso- 

 ciates. Nowhere common in this state. 



lA. On limestone near Elkmont, Limestone Co. 

 IB. Jackson, Madison, Morgan, Franklin and Blount Counties. 

 2A. Cullman County (Mohr). 

 2B. Fayette and Walker Counties. 

 3. Etowah, Talladega and Shelby Counties. 

 6C(?). Autauga and Montgomery Counties (Mohr). 

 7. Greene County. Near House Bluff, Autauga Countv. Chalk bluffs 

 near Demopolis. Dallas County (Cocks).
