than the stamens. Ovules many. Fruit a long, cylindrical capsule 

 separating into 2 valves. Seeds numerous, with long tufted hairs at 

 each end. 



About 10 species; 2 in America. 3 in the West Indies, and about 5 

 in China. Except the W. Indian species all have been introduced into 

 cultivation in Europe. The Catalpas are rapid growing ornamental 

 trees characterized by large, bell-shaped flowers in panicles and long, 

 slender pod-like capsules. They are suitable for street and lawn, 

 and wood-lot planting. The wood is coarse and straight grained, soft 

 but durable in contact with the soil, used for posts and railroad ties. 

 The bark has a bitter property used in. medicine as a tonic, diuretic 

 and vermifuge. Propagated by seeds and cuttings. Comparatively free 

 from insect and fungous attacks.
