The Hardy Catalpa, in the fertile bottom- 

 lands of the lower Ohio basin, has been known 

 to attain the height of 120 ft., when growing 

 in the forest, witii straight coliiiunar trunk 3 

 or 4 ft. in diameter, but it is usually a con- 

 siderably snuiller tree, and when isolated from 

 others develops a broad top of spreading 

 branches. 



It is quite as handsome a tree as the Common 

 Catalpa when in flower, and, though the 

 pyramids of flowers are smaller and of fewer 

 flowers, the individual flowers are distinctly 

 larger. Like the other species, too, its long 

 capsular pods swing from its leafless branches 

 long after the leaves have fallen, and, when 

 they open and liberate their light buoyant 

 seeds, the wind has opportunity to carrj' them 

 far from the parent tree before striking the 

 ground. 



Its light wood, of which a cubic foot, when 

 absolutely dry, weighs 25.96 lbs., is exceed- 

 ingly durable in contact with the soil, and is 

 proving to be one of the most profitable trees 

 to grow, at least in the middle west, for fence- 

 posts, railway ties, telegraph poles, etc. Large 

 plantations of the trees are being planted espe- 

 cially for these uses. 



Leaves broad-ovate, 8-14 in. long, cordate at 

 base, long-pointed, entire or with 1 or 2 lateral 

 lobes, not unpleasantly scented, at maturity 

 glabrous dark green above, pubescent and with 

 dark glands in the axils of the veins beneath. 

 Flowers in few-flowered panicles, 5-8 in. long and 

 broad; corolla campanulate, about 2% in. wide, 

 sparingly spotted with yellow and purple within, 

 lower lobe emarginate. Fruit: capsule 8-2(( in. 

 long. %-% in. thick, thick-walled; seeds about % 

 in. wide with light brown rounded wings terminat- 

 ing in a mostly wide fringe of hairs.
