1. Corallorrhiza trifida Chatelain. Early Coralroot. This species is 

 admitted to our flora upon the authority of Pepoon, who says : "Frequent 

 in the dune swale woods northeast of Dune Park" (Porter County), and 

 upon the basis of a specimen collected by Umbach in 1892 at Miller 

 (Lake County), now in the herbarium of the University of Wisconsin. It 

 was also reported from Floyd County but that record should, no doubt, be 

 referred to some other species.

2. Corallorrhiza Wisteriana Conrad. Wister Coralroot. Map 719. 

 Infrequent and rather local in the southern third of the state, rarely in 

 small colonies, but, where found, the specimens are usually a rod or more 

 apart. It grows in humus, generally on wooded, beech slopes, sometimes in 

 black or black and white oak woods, and rarely in white oak woods. This 

 is by far our most common coralroot.
