This genus, as Mr. Nuttall justly observes, is nearly allied 

 to MicRANTHEMUM of Mi c /lau X, but is sufficiently distin- 

 guisliecl by the very irregular corolla, bifid style, smooth seeds, 

 See. It differs from Lindernia in the same characters, and 

 jn having a 1 -celled capsule.

A large tree, 30 or more feet high, with few, large, irrcgulai 

 branches. Leaves round-cordate, 8 or 10 inches in diameter, 

 verticillatc in threes, smooth on the upper surface, pubescent 

 beneath, particularly on the nerves ; petioles long, swelled at 

 the base. Flowers in large pyramidal terminal panicles j 

 branches trichotomous. Segments of the calyoc obovate, mu- 

 cronatc. Corolla divided into 5 unequal crenate lobes, ele- 

 gantly variegated with yellow and purple; outside of the 

 Hower white. Fertile Jilanients incurved, aS long as the lube 

 of the corolla ; sterile filaments generally wanting in this vici- 

 nity ; an^Z/ers 2-lobed. 5^i//e as long as the stamens. Cafisule 

 a foot long, at first green, but becoming brown and a little 

 curved, remaining on the tree during the winter. Seeds fiat, 

 , winged, and tufted with hair at the summit. 

 IIab. Borders of fields and about farms; seldom found south or 

 the city of New-York. July. Catalfia. 



The Catalpa has evidently been introduced into this vici- 

 nity, as well as into most parts of the United States where it 

 is now found. Mr. Nuttall, who has travelled extensively in 

 our country, remarks, that it appears to have been introduced 

 by the aborigines in most of the habitats which he visited. He, 

 however, states, on the authority of Gov. Harrison, that it exists 

 in considerable quantities in the forests of the Wabash, Illinois 

 Territory.
