Carex gravida, also known as heavy-fruited sedge, [1] heavy sedge [2] or long-awned bracted sedge, [3] is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to southern parts of Canada and parts of the United States. [4]
The sedge can form a densely packed turf like arrangement with plants having no obvious rhizomes. It has 20 to 100 cm (7.9 to 39.4 in) long culms that are 2.5 to 8 mm (0.098 to 0.315 in) wide at the base and 0.7 to 1.6 mm (0.028 to 0.063 in) wide at the terminus. The leaves are surrounded by loose sheaths. The 4 to 8 mm (0.16 to 0.31 in) wide leaves have green and white striping at the terminal end with transverse veins on the back. The front side is covered in 2 to 7 mm (0.079 to 0.276 in) long projections. It forms inflorescences that have five to fifteen spikes that are 1 to 5 cm (0.39 to 1.97 in) in length and 8 to 15 mm (0.31 to 0.59 in) wide. [5]
The species was first described by the botanist Liberty Hyde Bailey in 1889 as published in Memoirs of the Torrey Botanical Club. [2] It has four synonyms;
It is mostly found growing in temperate biomes in south eastern Canada in the province of Saskatchewan in the west through Manitoba to Ontario in the east. [4] [1] In the United States it is found as far west as Montana in the north down to Texas and New Mexico in the south west. The range extends to New York in the north east to around Virginia in the south east. It has been introduced into Delaware, Maryland and North Carolina. [4]

Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
Carex binervis, the green-ribbed sedge, is a European species of sedge with an Atlantic distribution. It is found from Fennoscandia to the Iberian Peninsula, and occurs in heaths, moorland and other damp, acidic environments. It typically grows to a height of 15–120 cm (6–50 in), and has inflorescences comprising one male and several female spikes, each up to 45 mm (1.8 in) long. The utricles have two conspicuous green veins, which give rise to both the scientific name and the common name of the species. In the vegetative state, it closely resembles C. bigelowii, a species that usually grows at higher altitude. C. binervis was first described by James Edward Smith in 1800, and is classified in Carex sect. Spirostachyae; several hybrids with other Carex species are known.

Carex pilulifera, the pill sedge, is a European species of sedge found in acid heaths, woods and grassland from Macaronesia to Scandinavia. It grows up to 30 cm (12 in) tall, with 2–4 female spikes and 1 male spike in an inflorescence. These stalks bend as the seeds ripen, and the seeds are collected and dispersed by ants of the species Myrmica ruginodis.
