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]
