PLANER TREE. 
Planera ulmifoija. P. foliis petiolatis, oblongo-ovalibus , sensim angustcitis, 
acutis, basi obtusis, œqualiter serratis ; capsula scabrâ. 
Kentucky, Tennessee, the banks of the Mississippi and the Southern 
States, are the only parts of the American Republic where my father and 
myself have found the Planer Tree. Its wood is not used, and probably 
for this reason the tree has attracted no attention from the inhabitants, 
and has received no distinctive denomination ; to supply the deficiency, I 
have adopted the botanical name. 
I have more particularly observed the Planer Tree in the large swamps 
on the borders of the river Savannah, in Georgia. It is a tree of the 
second order, and is rarely more than 35 or 40 feet high and 12 or 15 
inches in diameter. Its bloom is early and not conspicuous. Its minute 
seeds are contained in small, oval, inflated, uneven capsules. The leaves 
are about an inch and a half long, oval-acuminate, denticulated, of a lively 
green, and a little like those of the European Elm, to which this species 
bears the greatest analogy. 
The wood of the Planer Tree is hard, strong, and seemingly proper for 
various uses ; it is probably similar in its characters to the analogous spe- 
cies in the north of Asia, the Siberian Elm ; but, as I have already re- 
marked, thé tree is rare and the wood neglected.
