Other info. - This species is rare in Missouri, currently reported from only two counties in the extreme northwest corner of the state. In fact, Missouri's populations occur at the very edge of the plant's natural range, which is mainly found within the upper Plains states. The plant is identified by its opposite, broadly elliptic leaves and axial flowers.
