Native Trees of Kentucky 131 



b. Catalpa Catalpa bignonioidcs. 



This Catalpa, or Indian liean, as it is sometimes called, is 

 found common in low river bottoms of the State. 



The wood, durable in contact with water and soil, is much 

 inferior to Catalpa speciosa ; it is used locally for fence posts. 



This Catalpa is also a favorite ornamental tree, taking rank 

 with Horse Chestnut and Paulownia. 



These two Catalpas are distinguished one from another only 

 by the expert, but four points of difference are guides to identi- 

 fication. 



Catalpa bignom'oicles has : 



1. Short, thick, low-branching trunk; 



2. Later flowering period ; 



3. Smaller flowers and pods ; 



4. Seeds smaller with wings, either twisted at the ends, 



or drawn out to a point.
