10 DIANDRIA. MONOGYNIA. 



genus Lindernia extends from the mountains of New 

 Hampsliire to the West India islands. 



16. CATALPA. Jussicu, Bigno^ia Catalpa, Lin, 

 (Catalpa-tree.) 



Calix S-parted. Corolla campanulate, tube 

 ventricose, border 4-lobed, unequal. Stamina 2, 

 fertile, filaments 3, sterile. Stigma bilamellate. 

 Capsule siliquaeform, lon.i^, cylindrir, 2-valved; 

 Dissepiment opposite to the valves. Seed mem- 

 branaceously margined and tufted at the extre- 

 mities. 



Trees with simple leaves, verticUlate in threes; flowers 

 paniculate. 



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

 pan.) liarely to be met with decidedly indig-enous in the 

 United States, and appears to have been introduced by 

 the aborigines-, hence its name of " Catatvba,^* derived 

 from a tribe of Indians residing on the Cataw ba river. In 

 most of the habitats of this tree given by the younger 

 IMichaux in his *' ^rbres Forestiers," which I have vi- 

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

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

 the indubitable existence of this tree in very considera- 

 ble quantities in the forests of the Wabasli, 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 

 eitiier on the banks of the Ohio, the Missisippi, or the Mis- 

 souri, rivers which 1 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 Bignonia longissima, a tree producing 

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

 worms or insects. Perhaps the same properties may be 

 common alsj to the C.-cordifoUa.

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

 Two of the filaments without anthers. Stigmata 

 ligulate. Capsule oblong^ 2 -celled, G-valved^
