end. The word catalpa is of Indian origin, and the meaning of 

 the word, doubtful. The genus is composed of seven species of 

 trees and shrubs, native to North America and Asia. 



Bark of old trees separating in thin flat scales; flowers 



numerous in dense panicles; flowers about 3 cm, (13^ 



inches) wide; calyx glabrous; lower lobe of corolla 



entire 1 Catalpa Catalpa. 



Bark of old trees deeply fissured, not scaly; flowers in 



loose panicles; flowers about 5 cm. (2 inches) wide; 



calyx usually pubescent; lower lobe of corolla notched 



at the apex 2 Catalpa speciosa. 



1. Catalpa Catalpa (Linnaeus) Karsten. Catalpa. {Catalpahignoni- 

 oides Walter). Plate 128. Bark of old trees grayish-brown, flaky, sepa- 

 rating in thin scales, 6-8 mm. (3^ inch) thick; leaves broadly ovate 

 or narrower, cordate at the base, taper-pointed, entire, or with 1 or 

 2 lateral lobes, blades 15 cm. (6 inches) long and 12 cm. (5 inches) 

 wide, at maturity light green and smooth above, paler and hairy 

 beneath, fetid when bruised; flowering period May or June; flowers 

 white, marked on the lower inner surface by 2 rows of yellow 

 blotches, the lower lobes marked with purple spots, the lower lobe 

 entire or nearly so, the upper lobe about half enclosing the other 

 lobes when expanding; tube of flower bell-shaped, wide as long; 

 fruit chestnut brown, grooves of pod shallow or usually wanting, 

 1.5-3.5 dm. (6-14 inches) long, usually about 8 mm. (1/3 inch) 

 thick, walls of pod thin, becoming flat after opening, each panicle 

 of flowers usually maturing 4-10 pods; seeds 1.5-2.5 cm. (^-134 

 inches) long and about 5 or 6 mm. (3^ inch) wide, silvery gray, 

 with the tuft of hairs on the end of the seed coming to a point, 

 and longer than the body of the seed. 



Distribution. Supposed to be native to parts of Florida, Georgia, 

 Alabama, and Mississippi. It has been introduced and naturalized 

 throughout the whole of the eastern United States. In Indiana it 

 has been used for years as an ornamental and shade tree, although 

 in fact, it has few qualities to recommend it. In some of the parks 

 where it has been planted it is being removed because the mature 

 pods make such a litter when they fall.

 TALFA. Plate 129. Bark of old trees grayish-brown, furrowed, at 

 last slightly flaky; leaves broadly to oblong-ovate, 1-3 dm. (4-12 

 inches) long, heart-shaped at the base, long taper-pointed, entire 

 or with 1 or 2 lateral lobes, at maturity dark green and smooth 

 above, lighter and hairy beneath, not ill-scented when bruised, 

 with clusters of dark glands in the axils of the veins beneath; flow-
