from Jefferson, Lake, and La Porte Counties. The report from Jefferson 

 County may probably be wrong since the author did not report Coral-

4. Corallorrhiza odontorhiza Nutt. Late Coralroot. Map 721 This 

 species is found in slightly acid soil in bare places in fallow fields, or in 

 rather sandy soil in deep humus in black and white oak woods. Very local 

 in its distribution but probably found here and there throughout the state. 

 It has been reported from other counties but wrong determinations are so 

 frequent that to enumerate them might lead to confusion.
