Keyed to V. primulifolia via MI Flora (need to verify w a broader ranging key); completely glabrous and capsules filled; seriously? lol; must be an introduction although it is "hesitantly" documented (potential hybrids) in Michigan counties to the south / southwest of this location; conifer swamp edge; rare, collected for botanist overseeing regional herbarium (S. Meades) to ID and will be preserved for future genetic research (much required!)
