|discussion=<p><i>Serenoa</i>, with a single polymorphic species, is endemic to the southeastern United States. It grows in a variety of habitats and communities including pine flatwoods, sand-pine scrub, and coastal sand dunes. It sometimes occurs in vast stands nearly excluding all other understory shrubs.</p><!--
--><p>The relationships of <i>Serenoa</i> are with <i>Acoelorraphe</i>, of the Caribbean Basin (N. W. Uhl et al. 1995), and perhaps Brahea, of Mexico and Central America (N. W. Uhl and J. Dransfield 1987).</p><!--
