 marked above with purple, hairy veins, colored beneath a lighter 

 purple, all entire, without petioles. Late May to September.

 scapes naked or bearing one or two small leaves, i to 2 

 feet high. In open woods and sandy, shady places from 

 Maine to Georgia and westward.

A much-branched, somewhat hairy plant rather taller than 

 the last. Flowers smaller. Thin, open woods, dry pastures 

 and fields from Nova Scotia to Georgia and Alabama and 

 westward.
