1. Pyrola secunda L. Map 1567. This species has been reported from 

 Lake, Porter, and Steuben Counties. There are specimens from Lake and 

 Porter Counties, collected by Nieuwland, now deposited in the herbarium 

 of the University of Notre Dame. The Lake County specimen was collected

 lanceolate-acuminate. 



This species reaches the southern limit of its range in northern Indiana.
