Campsis radicans (L.) Seemann 



strings and hell vine. It grows so rapidly that in one or two years it is 

 difficult to cultivate ground in which it becomes established. It prefers 

 alluvial bottoms and wherever this vine is noted in such a habitat it should 

 be destroyed or the capsules gathered and burned before the seed escape. 

 It is ornamental and has been widely planted which accounts for its 

 distribution. I doubt that it was a native of more than the Ohio River 

 Counties and the Lower Wabash Valley. It is still being planted and 

 recommended for ornamental planting but only by persons who are 

 ignorant of its potential weedy nature. My advice is to exterminate it 

 wherever found and never permit the vine to mature seed.

7727. CATALPA Scop. Catalpa 



Bark of old trees thin and scaly; odor of bruised leaves fetid; lower lobe of corolla 

 entire 1- C- bignonioides. 



Bark of old trees fissured and ridgy; odor of bruised leaves not fetid; lower lobe of 

 corolla notched at the apex 2. C. speciosa. 



1. Catalpa bignonioides Walt. (Catalpa Catalpa (L.) Karst.) Com- 

 mon Catalpa. Map 1876. This species has been freely planted as an 

 ornamental and, no doubt, does escape. I have seen it freely escaping along 

 a roadside in Johnson County and abundantly so in a few sandy, fallow 

 fields in northwestern Elkhart County. It is not recommended for 

 ornamental planting. If a species of catalpa is desired it is best to use 

 the next species.

2. Catalpa speciosa Warder. Hardy Catalpa. Map 1877. This is a 

 forest tree and was a native of the Lower Wabash Valley. I think I was 

 reliably informed by a pioneer of Perry County who told me that it was 

 a native in the lower valley of Deer Creek. The tree is not readily dis- 

 tinguished from the preceding species and reports for this species from 

 counties not indicated on the map should be regarded with suspicion.
