Imperata is a small but widespread genus of tropical and subtropical grasses, commonly known as satintails.[1][2]

Satintail grass species are perennial rhizomatous herbs with solid, erect stems and silky inflorescences. The best known species is Imperata cylindrica, which is recognized as a devastating noxious weed in many places and cultivated as an ornamental plant in others.[3][4][5][6]

The genus is named after Ferrante Imperato, a Renaissance apothecary who lived in Naples in the late 16th and early 17th Centuries. His collection included a herbarium.[7][8][9]
