|discussion=<p><i>Dichanthelium ravenelii</i> grows in dry, sandy wood¬lands of the southeastern United States. The primary panicles develop from early May through June, and are at least partly open-pollinated. The secondary panicles, which are produced from July through September, are cleistogamous. Putative hybrids with other species are very rare.</p>
