Discussion

Subspecies nemoralis is found in the open, disturbed soils of fields, roadsides, and gravelly embankments in the eastern deciduous forest area. Plants of the southeastern United States with a few elongated proximal branches in the arrays have been treated as var. haleana; that trait occurs farther north on occasion and not all shoots of the same plant have it. It is treated here as a synonym of the typical subspecies. Diploids occur throughout the range; tetraploids are scattered.
