Carex garberi Fern.
Habitat: Circumneutral shores and fens, in openings [Open wetland, not coastal or rivershore (non-forested wetland), non-tidal rivershore (non-forested, seasonally wet)]
Range: New Brunswick south to Maine, west to British Columbia, north to Alaska.
Aids to Identification: Members of this genus can be difficult to identify without careful examination of microscopic features and knowledge of general groups of species. Garber's Sedge is a member of the section Bicolores, a group recognized by its white and gold-orange lenticular-elliptical perigynia with a long sheath on the lowest carpellate bract. Garber’s sedge closely resembles Carex aurea. Garber’s sedge can be recognized by its blunt carpellate scales (acute in C. aurea). Carex garberi also retains its white perigynia in maturity; the perigynia turn orange at maturity for C. aurea.
