---><p><i>Cyperus lupulinus</i> was studied in detail (B. G. Marcks 1974). Ranges of the two subspecies overlap somewhat. <i>Cyperus lupulinus</i> subsp. lupulinus is found chiefly in the Great Plains, and subsp. macilentus is centered in the Northeast. It is seldom difficult to assign specimens to subspecies.</p><!--
+|elevation=0–1700 m
---><p>The hybrid of <i>Cyperus lupulinus</i> with <i>C. schweinitzii</i> is C. ×mesochorus Geise. It is occasionally encountered with the two parent species in the north-central states (Illinois, Indiana, Michigan, Minnesota, and Wisconsin) and has been recorded once from Quebec. The hybrid is similar in size to <i>C. schweinitzii</i>; it has fewer rays, inflorescence bracts 30–45º above horizontal, and floral scales with mucros 0.4–0.5 mm.</p>
