 rare in the northern part.

5a. Viola missouriensis X sororia Brainerd. I have this hybrid from 

 Knox, Sullivan, Tippecanoe, and Vanderburgh Counties. 



5b. Viola missouriensis X triloba. I have this hybrid from Daviess, 

 Greene, Knox, and Lawrence Counties. Brainerd named my specimens but 

 did not describe the hybrid. 



6. Viola papilionacea Pursh. Butterfly Violet. Map 1438. One of 

 our most common blue violets. Frequent in all parts of the state except 

 the area about Lake Michigan for which there are no records. In moist 

 woodland and clearings and along roadsides. This species is probably best 

 considered as a glabrate form of Viola sororia.
