|discussion=<p><i>Dichanthelium wilcoxianum</i> grows in dry prairies, especially in sandy or gravelly openings. It is restricted to the Flora region. The primary panicles, which are produced from mid-May to early June, are partially open-pollinated; the secondary panicles, which are produced in June, and occasionally also in September, are cleistogamous.</p><!--
--><p>Some specimens of <i>Dichanthelium oligosanthes </i>subsp.<i> scribnerianum</i> from the southern Great Plains that have prematurely elongating upper internodes resemble <i>D. wilcoxianum</i>, but they have greenish spikelets that are 1.7-2.4 mm wide, an orange spot at the base of the glumes, and larger basal rosettes.</p>
