Polygala curtissii /Milkwort Family
Milkworts have very pretty little individual flowers in the flowerhead (raceme). They remind me a bit of butterflies. I found these blooming at the East Overlook at Big South Fork National River and Recreation Area in Scott County in mid-August. It is in the Milkwort Family.
