Trees, or some exotic species shrubs, with opposite or rarely verticillate simple petioled 

 leaves, and large showy white or mottled flowers in terminal panicles or corymbs. Calyx 

 closed in the bud, splitting irregularly or into 2 lips in opening. Corolla-tube campanulate 

 or obconic, oblique, expanded above, 2-lipped, 5-lobed, the lobes all spreading, their margins 

 crisped. Anther-bearing stamens 2, ascending under the upper lip of the corolla; anther-sacs 

 glabrous, linear or oblong, divergent; sterile stamens (staminodia) 3, short (or occasionally 

 4 perfect didynamous stamens and i staminodium). Disk obsolete. Ovary sessile, 2-celled; 

 ovules in 2-several rows on the sides of the partition. Capsule elongated-linear, terete, 

 loculicidally dehiscent. Seeds flat, the large lateral wings dissected into capillary processes. 

 [The American Indian name of the first species below.] 



About 5 species, the following in eastern North America, 2 in eastern Asia. Type species : 

 Bignonia Catalpa L. West Indian trees referred to this genus prove to be distinct. 



Corolla thickly spotted within, i'-ij4' long, the lobes crimped. 

 Corolla little spotted, but purple-lined, 2' long, the lobes nearly flat.
