|discussion=<p>The most distinct species of the genus, Baileya pauciradiata has the most limited distribution and is, perhaps, the least abundant.</p><!--
--><p>Baileya pauciradiata also possesses cytotoxic sesquiterpene lactones, namely odoratin and paucin (J. J. Hoffmann et al. 1978).</p><!--
--><p>Baileya pauciradiata is connected to the moth Schinia pallicincta Smith, which is closely related to the species of noctuid moth that inhabits B. multiradiata. Schinia pallicincta occupies mostly sand dunes of southern California and uses B. pauciradiata as a primary feeding source (T. G. Myles and B. F. Binder 1990).</p><!--
--><p>Baileya pauciradiata has occasionally been found growing with or near B. pleniradiata; natural hybrids between them have not been recorded, nor have synthetic crosses been successful (R. C. Brown 1974). Brown supported the genetic isolation of the species from the other taxa by demonstrating complete barriers to gene exchange.</p>
