Taxonomic Comments
Considered native in North America by Kartesz (1999); Godfrey & Wooten consider this native in the plains and prairies of the Midwest, and introduced eastward. Three varieties recognized by Kartesz (1999), with var. annua and var. caudata widespread, and the questionably distinct var. macrocarpa only in Missouri, Arkansas, and Kentucky. Varieties not recognized by FNA (Vol. 21, 2006) or in the 2010 draft of Kartesz.
