Carex festucacea or fescue sedge is a species of sedge that lives in eastern North America. It has been described as "a soft, gray green, wisp, to 2', with narrow leaves and somewhat taller stems, topped by an interrupted spike, with lower spikelets, shaped a bit like an overflowing ice cream cone. The spike axis is often arched at the summit, but the alternating spikelets around the axis create a zig zag appearance. The seed sacs have a humped shoulder."

Carex klamathensis is a rare species of sedge known by the common name Klamath sedge. It is known from 15 or fewer populations in southern Oregon and three populations in the Klamath Region of northern California. It was described to science only in 2007. Its habitat includes fens and other wet habitat, on serpentine soils.This sedge grows from a long rhizome bearing clumps of stems. The leaves are glaucous, 2-6 mm wide, with papillae between and sometimes over the veins. The inflorescence consists of 2-3(-5) spikelets. The terminal spikelet is usually staminate, occasionally androgynous, gynecandrous, or pistillate. Staminate terminal spikes are 1.3-2.7 cm long, 2-5 mm wide, with 40-190 flowers. Lateral spikelets are pistillate, (0.6-)1.5-2.5 cm long, 4-7 mm wide, the uppermost usually 1.5-6 cm or more below the terminal spike, but sometimes attached as close as 0.3 cm below the terminal spike. Pistillate flower bracts are reddish brown, dark brown, or rarely gold, the midrib and surrounding area green, white, or light brown, the edges sometimes pale, 1.9-2.8 mm long excluding awn.Perigynia (utricles) are obovate to elliptic, 2.1-3.6 mm long, (0.8-)1.2-1.6(-1.8) mm wide, light green, tan, or whitish, sometimes marked with dark brown distally, papillose particularly toward the beak or rarely smooth, the base succulent when fresh and drying withered, the beak usually curved, the distance from beak tip to top of achene (0.1-)0.4-0.7(-1) mm. Stigmas 3 (occasionally 2 on 0-5%(-15%) of perigynia that have viable achenes). Achenes trigonous (lenticular if stigmas 2).Inconspicuous Carex klamathensis is easily confused with Carex hassei, which typically has 2 stigmas per flower and lenticular achenes. Unfortunately, populations of Carex hassei sympatric with Carex klamathensis in the Klamath Region often have a mix two- and three-styled flowers that produce viable lenticular and trigonous achenes, respectively. Up to 2/3 of the flowers may produce trigonous achenes.Carex klamathensis was discovered independently by botanists Peter Zika and Lawrence Janeway. Carex klamathensis is threatened by mining. In fact, most of one population has been obliterated by mining activities. Other threats include road building, recreational activities, and changes in drainage patterns.

Carex inops is a species of sedge known by the common name long-stolon sedge. It is native to northern North America, where it occurs throughout the southern half of Canada and the western and central United States. There are two subspecies; ssp. inops is limited to the west coast from British Columbia to California, while ssp. heliophila (sun sedge), is more widespread and is more common east of the Rocky Mountains.This sedge produces a loose clump of stems up to 50 centimeters tall. The stiff, narrow leaves persist, with dead ones remaining around the base of the plant. The inflorescence usually has pistillate spikes below staminate spikes. The plant grows from rhizomes and fibrous roots; despite its common name, it does not usually form stolons.This plant, particularly sun sedge (ssp. heliophila), is a dominant species in a number of ecosystems, such as many grasslands. On the prairies of the northern Great Plains it is codominant with grasses such as western wheatgrass (Pascopyrum smithii) and other wheatgrasses, big bluestem (Andropogon gerardi) and other bluestems, needle-and-thread grass (Hesperostipa comata) and other needlegrasses, and/or blue grama (Bouteloua gracilis) and other gramas. It is common on the tallgrass prairies of Kansas alongside bluestems and prairie sandreed (Calamovilfa longifolia). It can be a dominant species in Rocky Mountain meadows, woodlands in Nebraska, the Black Hills of South Dakota and Wyoming, and the plains of Saskatchewan. It can be found in each stage of ecological succession on grasslands. It can colonize blowouts, anthills, and prairie dog towns.Many types of animals consume this plant, particularly ssp. heliophila. It is considered a good forage for livestock because it is one of the first green plants to appear in the spring and animals such as cattle find it palatable.

Carex cespitosa is a species of perennial sedge of the genus Carex which can be found growing in tufts (caespitose), as the Latin specific epithet cespitosa suggests. The name is synonymous with Carex cespitosa f. retorta.The species is able to hybridise with the common sedge (Carex nigra) to produce a plant 20–50 centimetres (8–20 in) tall, flowering from May to June. The species can be found in all of Scandinavia, ranging from common to rare, and central parts of Europe, becoming rare to the west and towards the Mediterranean, and including isolated locations in Great Britain and the Iberian Peninsula.The species is often found in a mosaic with other Carex, but can become almost entirely dominant. It grows in very moist soil.
