Cyperus setigerus is a species of sedge that is native to central and southern parts of the United States, recorded from Kansas, Oklahoma, Texas, Missouri, and New Mexico.

Taxonomy
The original spelling of the name combination is Cyperus setigerus, Although the orthographic variant Cyperus setiger has been used in some later literature (e.g. McKenzie & Newbold 2020 ) as the classical spelling of the epithet in the nominative masculine is setiger. However, Articles 23 and 60 of the International Code of Nomenclature for algae, fungi, and plants do not allow for subsequent emendation in such cases, as does not meet any of the stated exceptions.
