|discussion=<p>Species 4 (4 in the flora).</p><!--
--><p>Molecular phylogenetic data have indicated that <i>Lagophylla</i> is sister to <i>Layia</i> (S. Carlquist et al. 2003). Members of <i>Lagophylla</i> are easily overlooked in the field; leaves usually wither before flowering and heads often close at midday. Ray laminae often shrivel greatly in pressed specimens (making lengths difficult to assess). The species are moderately interfertile (W. C. Thompson 1983); most do not co-occur and no natural hybrids have been documented.</p>
