Native distribution of Verbesina encelioides in the flora area is uncertain. Plants of Verbesina encelioides from ca. 100°W (e.g., c Texas) and eastward usually have auriculate petiole bases and have been called var. encelioides; plants from the west usually lack auricles and have been called var. exauriculata.
