--><p><i>Gundlachia</i> grows in arid habitats in rocky to sandy soils.</p><!--
--><p>Phylogenetic analyses (L. E. Urbatsch et al. 2003) demonstrated the polyphyly of genus Xylothamia G. L. Nesom, Y. Suh, D. R. Morgan & B. B. Simpson and showed that some species assigned there are more closely related to <i>Gundlachia</i>.</p>
