Abstract
Based on study of herbarium specimens, Cyperus rosattii is described as a new species from Venezuela. Known from a single collection from the Orinoco lowlands, it appears to be most similar to Cyperus swartzii and C. aggregatus. Similarly, Cyperus gonzaleziae is described as a new species from eastern Mexico (coastal region of Veracruz); it appears to be most similar to C. pallidicolor and C. regiomontanus.
