E. quercifolius is in Section Quercifolium of the Genus Erigeron, which means that it is more closely related to Erigeron species in the Western US and Central America like the Rio Grande Erigeron (Erigeron tenellus) and Darrel's Fleabane (Erigeron darrelianus) in Bermuda than it is to the other native species of Erigeron in Florida (E. annuus, E. pulchellus, E. strigosus, E. tenuis, and E. vernus)1,2.
