Carex amphibola, known as gray sedge, [2] is a species of flowering plant in the family Cyperaceae. [1] It was first formally named in 1855. [3] Carex amphibola is native to the eastern United States and Canada. [1]

Carex amphibola is commonly confused with Carex grisea , which has somewhat greener perigynia with more rounded tips, versus the gray-green coloring and angular tips of C. amphibola perigynia. The perigynia of C. amphibola are somewhat more clustered and spreading at maturity, while those of C. grisea are strongly ascending. [2]

Carex amphibola grows in mesic deciduous forests, often in loamy areas near streams. [4]
