|discussion=<p>Populations with at least the distal leaves entire have been called <i>Isocoma</i> pedicellata, and these apparently segregate geographically, at least to some extent (G. L. Nesom 1991c). Some plants have both entire and pinnatifid leaves; the distinction does not appear to warrant formal recognition.</p>
