COMPARING THE LEAVES OF DIFFERENT SPECIES OF CATALPA 
The leaves at the top are those-of C. bignonioides} characterized by their ovate shape, with 
entire margin and pubescence only on the lower surfaces. Those in the center 10w are of C. 
Kaempferi which are generally three-lobed with velvety pubescence only on their upper sur- 
faces. The leaves of the hybrid are shown at the Fottom. Characters of both parents are ex- 
pressed in these leaves which are generally three-loted and pubescent on toth surfaces. In 
color markings they more nearly represent the Japancse species. (Fig. 4.)
