Great work, Scott! Racemed Milkwort is one of those admirable denizens of the dry country, showing up in places that are very hot and well-drained.
Polygala = much milk, a reference to the milky sap. Polygama = many marriages, a reference to the many flowers, some of which are cleistogamous and attached to the roots, or on short racemes (above ground) at the base of the plant. Several species of Polygala smell like wintergreen near the base and among the roots. The plant in the second picture was re-planted (and even watered) after the picture was made.
Photographed July 2, 2008 in a Black Oak savannah in Porter County, Indiana. The next plant quiz is yours, Scott.
