Ranunculus glacialis, the glacier buttercup or glacier crowfoot, is a plant of the family Ranunculaceae. It is a 5-10(-20) cm high perennial herb. Often with a single relatively large flower, with 5 petals first white later pink or reddish. The underside of the 5 sepals are densely brown-hairy.

Carex chordorrhiza, commonly called creeping sedge or string sedge, is a species of perennial plant in the family Cyperaceae with Holarctic distribution growing in acidic bogs.
Carex canescens L. is a perennial species of plants in the family Cyperaceae growing in damp forests and wetlands. It is widespread across much of Europe, Asia, Australia, New Guinea, North America, Greenland and southern South America.
Carex buxbaumii is a species of sedge known as Buxbaum's sedge or club sedge. It is native to much of the northern Northern Hemisphere, from Alaska to Greenland to Eurasia, and including most of Canada and the United States. It grows in wet habitat, such as marshes and fens. This sedge grows in clumps from long rhizomes. The stems are 75–100 cm (30–39 in) in maximum height. The leaves are narrow and small. The inflorescence has a bract which is sometimes longer than the spikes. The fruits have dark-colored bracts and a sac called a perigynium or utricle which is gray-green and rough in texture.
Carex capitata is a species of sedge known by the common name capitate sedge. It has a circumboreal distribution including Norway, Russia, Siberia, Alaska, Canada and Greenland. Growing in wet places in boreal forests and mountain meadows in alpine climates.
Carex lyngbyei is a species of sedge known by the common name Lyngbye's sedge. It is native to the west coast of North America from Alaska to California, where it "is the common sedge of the Pacific coastal salt marshes." It is also known from Greenland and Iceland. It prefers to grow in silty sediment rather than sand and in habitat with brackish water, such as salt marshes. This sedge produces stems 25 centimeters to well over one meter tall from a network of long rhizomes. The leaves have reddish brown sheaths which do not have spots. The inflorescence produces stiff, nodding spikes on peduncles. The fruit is coated in a leathery yellowish brown sac called a perigynium. This is a pioneer species, one of the first plants to colonize the mud of tidal flats in its range.
Carex pensylvanica is a species of flowering plant in the sedge family commonly called Pennsylvania sedge. Other common names include early sedge, common oak sedge, and yellow sedge.
Carex bigelowii is a species of sedge known by the common names Bigelow's sedge, Gwanmo sedge, and stiff sedge. It has an Arctic–alpine distribution in Eurasia and North America, and grows up to 50 centimetres (20 in) tall in a variety of habitats.
Carex bromoides, known as brome-like sedge, brome-sedge, and dropseed of the woods, is a species of sedge in the genus Carex. It is native to North America.
Carex bebbii, Bebb's sedge, is a species of sedge native to the northern United States and Canada. Carex bebbii grows in a variety of wetland habitats such as lakeshores, streambanks, ditches, meadows, swamps, and seeps. It forms dense tufts with culms up to 90 centimeters tall.

Carex bicolor, the bicoloured sedge, is a species of sedge native to North America, Northern Europe and Northern Asia. The International Union for Conservation of Nature has assessed the plant's conservation status as being of least concern because it has a widespread distribution and faces no particular threats.
Carex atrata, called black alpine sedge, is a widespread species of flowering plant in the genus Carex, native to Greenland, Iceland, and most of Europe, plus scattered locations across temperate Asia, including Anatolia, Siberia and the Himalaya, as far as Taiwan and Japan. Its chromosome number is 2n=52, with some variants reported, e.g. n2=54 for Greenland material.
