5478. CUPHEA P. Br. 



1. Cuphea petiolata (L.) Koehne. (Parsonia petiolata (L.) Rusby.) 

 Cuphea. Map 1467. Prefers sandy soil in dry situations but adapts itself 

 to moist conditions. Rather frequent in the southern half of the state in 

 open woodland, pastures, and fallow fields and along roadsides. Our 

 Steuben County specimen was collected in 1928 by Anna May Weatherwax 

 on the border of a cornfield along Little Crooked Lake northwest of Angola. 

 No doubt this specimen was adventive. The species has a weedy nature. 

 I had it under cultivation several years ago and it reproduced so abundant- 

 ly that I feared it might become a weed so I exterminated it.
