 vcntricose, border 4 lobed, unequal. Stamina 2, 

 fertile, filaments 3, sterile. Stigma bilainellate. 

 Capsule siliqu?ef jrm, loiii^, cylindrir, 2-valvcd;

Species. 1. C. cordifoUa^ (said also to be anative of Ja- 

 paii.) Rarely to be met With decidedly indig-enotis in the 

 United States, and appears to have been introduced by 

 the aborigines; hence its name of *' Catcnvba," dtrived 

 from a tribe of Indians residing on the Catawba river, lii 

 most of the habitats -f ihis tree given by the younger 

 Michaux in his " Arbres Forestiers," which I have vi- 

 sited, if existing at all, it had evidently been introduc- 

 ed. 1 am informed, however, by Govenvor Harrison, of 

 the indubitable existence of this tree in very considera- 

 ble quantities in the forests of the Wabash, Illinois Terri- 

 tory, where its wood is even split for rails; still even here 

 it is extremely local, and 1 have never once met with it 

 either on the banks of the Ohio, the Missisippi, or the .Mis- 

 souri, rivers which I have ascended or descended thou- 

 sands of miles. In the warmer states it does not appear 

 to grow with any degree of vigour. 



There is another species of this genus in the West In- 

 dia islands, viz. the Bignoiiia longissima, a tree produ( ing 

 very hard wood, wliich is not liable to be destroyed by 

 worms or insects. I^erhaps the same properties may be 

 common also to the C. cordifolia.

 sion cleft. Corolla 5 -cleft; lamina nearly equal.
