|discussion=<p>In addition to <i>Cyperus manimae </i>var.<i> asperrimus</i>, G. C. Tucker (1994) recognized var. manimae and <i></i>var.<i> divergens</i> from northern Mexico, which might be found in Arizona, New Mexico, or west Texas. All three varieties occur nearly throughout the range of the species; intermediates are scarce, and assigning specimens to a particular variety is seldom difficult. <i>Cyperus manimae</i> var. manimae differs from <i></i>var.<i> asperrimus</i> in having glabrous culms and bracts, and <i></i>var.<i> divergens</i> differs in having cuspidate floral scales.</p>
