An upright square-stem, horizontally held opposite 3-lobed leaves and compact clusters of flowers in the upper leaf axils characterize this 2 to 4 foot tall herb. The small flowers (about inch long) are pink to pale purple and 2-lipped with the upper lip arching and having a fuzzy upper surface. Lower leaves long-stalked and cut deeply to form 3 to 5 lobes.
