2. Pyrola elliptica Nutt. Shinleaf. Map 1568. An infrequent to rare 

 plant in some of the counties of the lake region. It is usually found in cool, 

 shady places in sandy soil at the base or on the lower part of black and 

 white oak slopes where these border a lake, swamp, or pond. Where it is 

 found it is usually frequent to common. This is by far our most common 

 species of the genus.

3. Pyrola chlorantha Swartz. Map 1569. A specimen of this species 

 was collected by Hill, May 25, 1878, in sandy woods near Whiting, Lake 

 County. It is in the herbarium of DePauw University. It has more recently 

 been collected by Nieuwland & Just in a tamarack swamp on the north side 

 of Bass Lake, St. Joseph County, June 18, 1930. The specimens are very 

 young but seem to be sufficiently distinct. Both specimens belong to the 

 typical form.
