--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>yellowish-green. <b>Culms</b> compressed, densely cespitose. <b>Sheaths</b> strongly keeled, 3-6 mm wide from the keel to the margins, truncate or broadly auriculate, occasionally ciliate distally; ligules minute, membranous; blades 0.7-1.5 mm wide from the blunt keel to the margins, to 2.5 mm wide overall, thick, curved or flexuous, rigid, glabrous or scabridulous on both surfaces and along the margins, bases much narrower than the subtending sheaths, margins often sparsely ciliate, with long, slender hairs near the base. <b>Panicles</b> slender, purplish, long-exserted; branches few, appressed or ascending, with relatively few spikelets. <b>Spikelets</b> 2.4-2.8(3) mm, purplish, glabrous, obliquely set on the pedicels, mostly abortive. <b>Lower</b> glumes 1.6-2 mm, often divergent; upper glumes and lower lemmas subequal, often spreading apart.</span><!--

|discussion=<p><i>Panicum rigidulum </i>subsp.<i> abscissum</i> is endemic to central Florida. It usually grows in marshy, sandy ground, but is occasionally found in dry, sandy sites (e.g., the type specimen, collected near Lake Sebring).</p><!--
--><p><i>Panicum rigidulum </i>subsp.<i> abscissum</i> is very similar vegetatively and reproductively to <i></i>subsp.<i> pubescens</i> and <i></i>subsp.<i> combsii</i>. In addition, its spikelets also suggest those of <i>P. virgatum</i>.</p>
