Scientific NameCommon NameSummary
Bolboschoenus maritimusBayonet-grassNo collections of this species in ARCTOS from the region. Hullten shows a single record from Juneau area and suggests the species is probably not native to the region.
Carex albonigraBlack-and-white SedgeCollections in ARCTOS from nunataks on the Candian side but near the border.
Carex anthoxantheaYellow-flowered SedgeFairly Common sedge of wet meadows and grassy areas. Collections in ARCTOS from across the region.
Carex aquatilisSitka SedgeCommon rhizomatous sedge of wet areas. Collections in ARCTOS from across the region.
Carex arctaNorthern Clustered SedgeA single collection of an immature specimen from Ward Lake near Ketchikan is the only one mapped from the region in ARCTOS. FNA treatment does not include Alaska in the range of this species (though ARCTOS has several records from elsewhere in the state)
Carex atherodesWheat SedgeNot currently known from the region, but a collection from Flannigan Slough on the Taku River (shown on the e-Flora BC map) is close to the border.
Carex athrostachyaSlenderbeak sedgeTuft formed sedge with head-like aggregate of spikes A single 1917 unmapped collection from Juneau in ARCTOS. Hulten shows a second dot at Skagway. Possibly introduced at those locations and not currently established?

Carex aureaGolden SedgeNo collections in ARCTOS from the region. Hulten's map shows records from Glacier Bay and near Haines.
Carex bebbiiBebb's sedgeTufted sedge with multiple spikes crowded into an oval head No collections in ARCTOS from the region. Hulten indicates a record from near the border east of Juneau (it's not clear which side of the border)
