--><p>The circumscription of Ecliptinae adopted by H. Robinson (1981) and followed here differs from the treatment by P. O. Karis and O. Ryding (1994), who placed <i>Eclipta</i> as unassigned to a subtribe and placed <i>Echinacea</i> in Rudbeckiinae, <i>Acmella</i>, <i>Heliopsis</i>, <i>Sanvitalia</i>, and <i>Zinnia</i> in Zinniinae, <i>Berlandiera</i>, <i>Chrysogonum</i>, <i>Engelmannia</i>, <i>Lindheimera</i>, and <i>Silphium</i> in Engelmanniinae, and <i>Balsamorhiza</i> (including <i>Agnorhiza</i>), <i>Borrichia</i>, <i>Calyptocarpus</i>, <i>Encelia</i>, <i>Enceliopsis</i>, <i>Flourensia</i>, <i>Geraea</i>, <i>Helianthella</i>, <i>Jefea</i>, <i>Lasianthaea</i>, <i>Melanthera</i>, <i>Pascalia</i>, <i>Phoebanthus</i>, <i>Sphagneticola</i>, <i>Synedrella</i>, <i>Verbesina</i>, <i>Wedelia</i>, and <i>Wyethia</i> (including <i>Scabrethia</i>) in Verbesininae. Based on studies of chloroplast DNA sequences, J. L. Panero (2005) placed <i>Encelia</i>, <i>Enceliopsis</i>, <i>Flourensia</i>, <i>Geraea</i>, and <i>Helianthella</i> together in Enceliinae and <i>Acmella</i> in Spilanthinae, indicating a sister relationship between Spilanthinae and traditionally circumscribed Zinniinae.</p>
