|discussion=<p><i>Opizia</i> is a North America genus of two species. Both species are probably native to Mexico, but one of them now grows, possibly from introductions, in Florida and the West Indies.</p><!--
--><p>Columbus (1999) argued that <i>Opizia</i> should be included in <i>Bouteloua</i>. The traditional treatment is maintained here, pending corroboration of his results from a wider range of data.</p>
