|discussion=<p><i>Senecio mohavensis</i> is similar to S. flavus (Decaisne) Schultz-Bipontinus of the Mediterranean region and southwest Asia, which raises phytogeographic questions (cf. A. Liston et al. 1989; Liston and J. W. Kadereit 1995; M. Coleman et al. 2001). The last cited study showed that a previously recognized variety of S. flavus is more closely related to <i>S. mohavensis</i> than to S. flavus and a new combination was made: <i>S. mohavensis</i> <i></i>subsp.<i> brevifolius</i> (Kadereit) M. Coleman.</p>
