--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>cespitose, pale bluish- or grayish-green. <b>Culms</b> erect to ascending, densely puberulent, longer hairs often present also, at least on the lower portion of the culms; nodes puberulent; fall phase with spreading or decumbent culms, branching early from most nodes, secondary blades not as greatly reduced or as densely crowded as in subspp. acuminatum, fasciculatum, implicatum, and leucothrix. <b>Cauline</b> sheaths pubescent, their pubescence similar to that of the culms but some¬what less dense; midculm sheaths about 1/2 as long as the internodes; ligules 1-1.5 mm; blades 3-7 cm long, 3-7 mm wide, relatively firm, often ascending, abaxial sur¬faces densely puberulent to nearly glabrous, adaxial sur¬faces glabrous or sparsely pilose near the base, margins whitish-scabridulous. <b>Spikelets</b> 1.5-1.9 mm, broadly ellipsoid or obovoid, puberulent.</span><!--

|discussion=<p><i>Dichanthelium acuminatum </i>subsp.<i> columbianum</i> grows in sandy woods or clearings in the northeastern portion of the species range. It is much less common than the other eastern subspecies of <i>D. acuminatum</i>. Occasionally, it resembles the more widespread <i></i></i>subsp.<i><i> fasciculatum</i>, <i></i></i>subsp.<i><i> implicatum</i>, and <i></i></i>subsp.<i><i> lindheimeri</i>.</p><!--
--><p>The culms and sheaths of <i>Dichanthelium acuminatum </i>subsp.<i> columbianum</i> are always puberulent with very short hairs. This puberulence should not be confused with the slightly longer hairs that develop on the secondary branches of other taxa.</p>
