SALICACEAE 103 



little to recommend them except rapid growth. Three varieties 

 of it are known to the horticultural trade, and two wild varieties 

 have been described. The "Carolina poplar" (F. Eugcnci) is 

 believed to be a hybrid of ICuropean origin, between P. dcltoidcs 

 and the Lombardy poplar [P. nigra Italica).

Grows on the banks of the large muddy rivers where they are 

 subject to considerable fluctuation, and also along creeks, branches 

 and ditches in calcareous regions. Its distribution by regions is 

 about as follows : 



IB. Along the Tennessee River all the way across the state. Reid's 

 Gap, Blount County (perhaps not native). 



2B. Extends up the Warrior River a few miles above Tuscaloosa. 



3. Along the Coosa River near Gadsden and the Cahaba in Bibb 

 County. 



6A. Along the Warrior. Cahaba and Tallapoosa Rivers. 



6C. Common on the Alabama River, less so on the Warrior. 



7. Common on rivers and creeks and even along ditches between 

 fields. 



8. Nearly as common as in the black belt, in similar situations. 



9. On rivers and creeks. Sumter, Marengo and Wilcox Counties. 

 lOE. On Conecuh and Pea Rivers, Pike County. 



low. Common on rivers and larger creeks, and occasionally along 

 small creeks and ditches. 



11. Frequent along rivers and creeks. 

 14. Upper part of the delta. 



Populus heterophylla, L. 



A smaller tree than the preceding, not large or abimdant 

 enough in Alabama to be of any importance. 



Dr. ]\Iohr reported this from ^Montgomery and Clarke Coun- 

 ties, and Prof. Cocks reported two or three trees in Dallas County, 

 but I have seen it in Alabama only in the lower part of the Mobile 

 delta, where it is common but not abundant. (It also grows in 

 similar situations along the Apalachicola River in Florida.) 



Populus alba, L. (European) White Popl.\r. 



A small to medium-sized tree, with whitish bark covered with 

 something that rubs off like chalk, and small coarsely toothed 

 leaves dark green above and white-downy beneath. 



A native of Europe, cultivated for ornament and shade, but 

 not very desirable because it sends up suckers from the roots. Runs 

 wild in the northern parts of the state, and near Tuscaloosa, 

 Mobile, and doubtless other places.
