It is native to the United States from Florida north as far as Ohio, Illinois, and Pennsylvania, west to Texas, Oklahoma, and Kansas.[4]Elephantopus carolinianus is a perennial herb sometimes as much as 120 cm (4 feet) tall. Leaves are elliptic or ovate to lanceolate, up to 12 cm (5 inches) long, darker on the upper side than they are on the lower side. The plant produces numerous small flower heads in a tight cluster, each head generally containing only 4-5 florets.[5] References1. ^The Plant List Elephantopus carolinianus Raeuschel 2. ^{{PLANTS|id=ELCA3|taxon=Elephantopus carolinianus|accessdate=21 June 2015}} 3. ^{{cite book|last1=Weakley|first1=Alan S.|title=Flora of the Southern and Mid-Atlantic States|date=May 2015|publisher=The University of North Carolina Herbarium|location=Chapel Hill, NC, USA|page=1115|url=http://www.herbarium.unc.edu/FloraArchives/WeakleyFlora_2015-05-29.pdf|accessdate=8 July 2015}} 4. ^Biota of North America Program 2014 county distribution map 5. ^Flora of North America, Elephantopus carolinianus Raeuschel, Nomencl.
