Abstract

<i>Cyperus pacificus </i> (Ohwi) Ohwi var. <i>margoinflatus </i> S. Fujii, a new variety of <i>C. pacificus </i> (Cyperaceae) is described. It closely resembles <i>C. pacificus </i> var. <i>pacificus </i> in the oblong-ellipsoid achenes with winged margins, but the margins are well inflated with spongy parenchyma. It usually occurs in the dried bottoms of irrigation ponds, and often intermixed with other species of Cyperaceae such as <i>C. extremiorientalis </i> Ohwi, <i>C. nipponicus </i> Franch. et Sav. var. <i>nipponicus </i> and var. <i>spiralis </i> Ohwi, <i>Fimbristylis dipsacea </i> (Rottb.) C.B. Clarke, and <i>F. squarrosa </i> Vahl var. <i>esquarrosa </i> Makino. A key to the new variety and closely related taxa is also provided.
