--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual, cespitose, 5–50 cm, base soft; rhizomes absent. <b>Leaves</b> nearly distichous, 1/2 to equal length of culms; sheaths bristlyciliate apically, backs glabrous or hirtellous; ligule present, complete; blades narrowly linear, 1–1.5(–2) mm wide, flat to shallowly involute, margins ciliate-scabrid, adaxial and abaxial surfaces glabrous or pubescent. <b>Inflorescences</b>: anthelae simple or compound, mostly open, diffuse, ascending-branched, longer than broad; scapes slender, 1 mm thick, angular; proximalmost involucral bract longer or shorter than anthela. <b>Spikelets</b> tan to brown or redbrown, ovoid to lance-ovoid, 3–8 mm; fertile scales broadly oblong to ovate, 2 mm, acute to obtuse-angled, smooth, midrib reaching apex or excurrent as mucro. <b>Flowers</b>: stamens 1(–2); styles 2-fid, flat, fimbriate. <b>Achenes</b> white to brown, often iridescent, lenticular or obovoid to pyriform-obovoid, 1 mm, cancellate, with 5–12 longitudinal ribs per side, alternating with as many rows of horizontally rectangular pits; warts of achene more usually distributed, or achene (rarely) smooth. <b>2n</b> = 30.</span><!--

|phenology=Fruiting summer–fall, all year southward.
|habitat=Various moist to wet substrates, often on exposed, recently disturbed soils around or in shallow temporary pools in outcrops, in savannas, fields, and paddies

|discussion=<p>The extensive, yet incomplete, synonymy above partly illustrates the polymorphic nature of <i>Fimbristylis annua</i>, there being many “stabilized” morphs in specialized habitats and much exchange of achenes mixed with grass seeds (particularly rice).</p>
