|discussion=<p>Gymnopogon ambiguus grows in sandy pine woodlands of the southeastern United States, Haiti, and the Dominican Republic. It often grows with G. brevifolius, from which it differs in being more robust, having long, wider leaves, longer lemma awns, and, usually, having panicle branches that are spikelet-bearing to the base. Although spikelets of Gymnopogon ambiguus usually have only one floret, several plants from Texas have been found in which two florets per spikelet were the norm.</p><!--
--><p>There is an 1853 collection of G. ambiguus supposedly from Dona Ana County, New Mexico, but there have been no recent collections from anywhere near there; it is possible that the locality data on the label are incorrect.</p>
