Abstract
The synonymy of several Cyperus taxa is proposed in here, as well as a new combination and also a new status for C. impolitus Kunth. This paper presents C. aggregatus var. gigas (Lindm.) Guagl. as a synonym of C. aggregatus (Willd.) Endl., as well as C. rigens var. capitatus J. Presl & C. Presl, C. rigens ssp. serrae (Boeck.) T.M. Ped., C. rigens ssp. rigens var. maximus (Kük.) T.M. Ped., and C. rigens ssp. rigens var. selmirae T.M. Ped. as synonyms of C. rigens J. Presl & C. Presl var. rigens. A new combination, C. rigens var. impolitus (Kunth) Hefler & Longhi-Wagner, became a new status for C. impolitus Kunth.
