--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>cespitose. <b>Basal</b> rosettes poorly differentiated; blades similar in shape to the lower cauline blades, narrow, ascending. <b>Culms</b> 10-45 cm, erect to spreading, lower 4-10 internodes telescoped together, less than 2 cm, upper 2 internodes elongated; nodes bearded; internodes pubescent to subglabrous; fall phase a dense mass of erect blades and foreshortened branches that arise from the basal culm nodes, about 54 of the branches sterile, others with small, narrow, secondary panicles of 3-7 spikelets that remain enclosed within the sheaths. <b>Cauline</b> leaves 2-4; sheaths longer than the internodes, glabrous or densely ascending-pilose; ligules about 0.5 mm; blades 6-15 cm long, 1-4 mm wide, green to grayish-green, sometimes involute, glabrous or densely pilose, apices long-tapering, lower blades small to vestigial, upper 2 or 3 blades longer and stiffly erect. <b>Primary</b> panicles 3-6 cm long, 1.5-3 cm wide, usually long-exserted (sometimes contracted and remaining basal), with 7-25 spikelets. <b>Spikelets</b> 3.2-4.3 mm long, 1-1.7 mm wide, ellipsoid-pointed, glabrous or finely pubescent. <b>Lower</b> glumes 1.2-1.6 mm, narrowly triangular; upper glumes and lower lemmas exceeding the upper florets by 0.2-1 mm, forming a pointed beak, upper florets 1.9-3.1 mm, obovoid, minutely umbonate. <b>2n</b> = 18.</span><!--

|discussion=<p><i>Dichanthelium depauperatum</i> grows in dry, open woodlands and open, disturbed areas, especially on sand. It is restricted to the Flora region. The primary panicles, which are rarely open-pollinated, are produced from May to early June; the secondary, cleistogamous panicles are produced from late June through July (rarely in fall). The species is linked with <i>D. perlongum</i> and <i>D. linearifolium</i> by occasional hybrids and hybrid derivatives. In the northern United States and Canada, 80-90% of the plants are glabrous and have been called <i>Panicum</i> depauperatum var. psilophyllum Fernald, P. depauperatum var. involutum (Torr.) Alph. Wood, or, if the primary panicles remain near the base, P. depauperatum forma cryptostachys Fernald; in this treatment, none of these is recognized as a distinct taxonomic entity. The frequency of pilose plants increases southward, where some populations are entirely pilose.</p>
