Taxonomic Comments

At one time, USFWS assigned G. semicalva var percalva a '3B' status. Kartesz (1999) lumps G. semicalva var percalva into G. parviflora. Kartesz (1999) believes this species to be exotic throughout North America, but USDA-ARS (2005) notes that its "probable native range [extends] from s.w. United States to South America ". Flora of North America Editorial Committee (2006) distinguishes Galinsoga parviflora var. semicalva and considers it native in Arizona, New Mexico, and Texas while Galinsoga parviflora var. parviflora is considered to be introduced in North America.
