Carex haematosaccus is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to central and eastern parts of Madagascar. [1]
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large: botanists have described some 5,500 known species in about 90 genera, the largest being the "true sedges" with over 2,000 species.
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons.
Carex is a vast genus of nearly 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Carex flacca, with common names blue sedge, gray carex, glaucous sedge, or carnation-grass,, is a species of sedge native to parts of Europe and North Africa. It is frequent in a range of habitats, including grasslands, moorlands, exposed and disturbed soil, and the upper edges of salt marshes. It has naturalized in eastern North America.
Yanal Bog is a 1.6 hectare biological Site of Special Scientific Interest on the southern edge of the North Somerset Levels, just north of the village of Sandford, North Somerset. It was notified as an SSSI in 1988.
Lambert's Castle is an Iron Age hillfort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology. The hillfort is designated a scheduled monument together with a bowl barrow, the sites of a post-medieval fair and a telegraph station. The site was on the Heritage at Risk Register but was removed in 2022 as a result of the Hillforts and Habitats Project.
Carex vesicaria is an essentially Holarctic species of sedge known as bladder sedge, inflated sedge, and blister sedge. It has been used to insulate footwear in Norway and among the Sami people, and for basketry in North America.
Carex riparia, the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest Carex, growing up to 130 cm tall, with glaucous leaves up to 160 cm long. It hybridises with a number of other Carex species, including the closely related Carex acutiformis – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass.
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 spicata is a species of sedge in the genus Carex.
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.
Carex panicea, commonly known as carnation sedge, is a plant species in the sedge family, Cyperaceae. It is known as grass-like sedge and can be found in Northern and Western Europe, and also in north-eastern North America. The plant produces fruits which are 3–4 millimetres (0.12–0.16 in) long, are egg shaped and spiked. Both male and female species leaves are pale blue on both sides.
Carex sect. Ovales is a section of the genus Carex, containing around 85 species of sedge. It is the most diverse section of the genus in North America, containing 72 species:
Carex subg. Carex is a subgenus of the sedge genus Carex. It is the largest of the four traditionally recognised subgenera, containing around 1400 of the 2000 species in the genus. Its members are characterised by the presence of one or more exclusively male (staminate) terminal spikes, quite dissimilar in appearance from the lateral female (pistillate) spikes below. In most species, the female flowers have three stigmas, but a few species, including Carex nigra, have female flowers with only two stigmas.
Carex subg. Vignea is a subgenus of the sedge genus Carex, containing around 300 of the 2000 species in the genus. Its members are characterised by having bisexual, sessile spikes, where the female flowers have two stigmas each.
Carex pulicaris, the flea sedge, is a species of sedge in the genus Carex native to Europe.
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.
