1. Cladrastis lutea (Michx. f.) Koch. Yellow-wood. Map 1205. A 

 single colony of this species was found in 1933 in a deep, wooded ravine 

 in the Brown County Game Preserve. It was reported to be present 

 also in a nearby ravine. I was informed that the former owner of the 

 land had cut one tree and had it sawed into boards. The nearest known 

 location of this species is 40 miles south of Evansville. The species may 

 be exceptionally rare or may have been overlooked.

 dry, sandy prairies and low, open, black oak woods throughout the north-
