Juncaceae is a family of flowering plants, commonly known as the rush family. It consists of 8 genera and about 464 known species of slow-growing, rhizomatous, herbaceous monocotyledonous plants that may superficially resemble grasses and sedges. They often grow on infertile soils in a wide range of moisture conditions. The best-known and largest genus is Juncus. Most of the Juncus species grow exclusively in wetland habitats. A few rushes, such as Juncus bufonius are annuals, but most are perennials. Despite the apparent similarity, Juncaceae are not counted among the plants with the vernacular name bulrush.
Juncus is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species.
There are over 190 vascular plant species on the Norwegian Arctic archipelago of Svalbard. This figure does not include algae, mosses, and lichens, which are non-vascular plants. For an island so far north, this number of species constitutes an astonishing variety of plant life. Because of the harsh climate and the short growing season, all the plants are slow growing. They seldom grow higher than 10 cm (4 in)
Juncus effusus is a perennial herbaceous flowering plant species in the rush family Juncaceae, with the common names common rush or soft rush. In North America, the common name soft rush also refers to Juncus interior.
Calcifugous grasslands and montane communities are botanical groupings in the British National Vegetation Classification system.
NVC community U6 is one of the calcifugous grassland communities in the British National Vegetation Classification system.
Juncus articulatus is a flowering plant species in the rush family Juncaceae. It is known by the common name jointleaf rush or jointed rush, which can also refer to J. kraussii from Australia. It is native to Eurasia, Canada, Greenland and much of the United States. It grows in moist areas, such as wet sand, and thrives in calcareous soils. J. articulatus was found to be more sensitive to drought and salt stress than its congeners J. acutus and J. maritimus. It is a perennial herb producing mainly erect stems from a short rhizome. The stem may root at nodes, and it generally has one or more flattened hollow cylindrical leaves up to 10 centimeters long. Transverse internal partitions or joints may be seen or felt in the leaf of the plant.
Rhytidiadelphus squarrosus is a species of moss known as springy turf-moss in the United Kingdom, and square goose neck moss in the United States. It is widespread in Eurasia and North America, and has been introduced to the Southern Hemisphere. It has broad ecological tolerances, and is usually found in man-made habitats such as lawns and golf courses. It is most closely related to R. subpinnatus, with which it is often confused.
Oreojuncus trifidus is a species of rush known by the common names highland rush and three-leaved rush. It is native to the Northern Hemisphere, where it is an arctic/montane species with an amphi-atlantic distribution.
Juncus filiformis, called the thread rush, is a species of flowering plant in the genus Juncus, with a circumboreal distribution. It has been introduced to South Georgia Island. It is typically found in wetlands, on the borders of lakes and streams.
Juncus bulbosus, the bulbous rush, is a species of flowering plant in the family Juncaceae, native to Iceland, the Faroes, Europe, Macaronesia, and northwest Africa. It has been introduced to Australia, New Zealand, and some locations in northern North America. It is capable of nuisance growth in lakes and streams.
Juncus inflexus, the hard rush, is a species of flowering plant in the family Juncaceae, native to Europe, Asia and Africa, and introduced in Sri Lanka, Java, Île Amsterdam and Île Saint-Paul, Victoria in Australia, New Zealand, Uruguay, and eastern North America. It is a glycophyte (non-halophyte).
Juncus alpinoarticulatus, called the northern green rush and the alpine rush, is a species of flowering plant in the genus Juncus, with a circumboreal distribution. It prefers wet sandy soils, peat bogs, acidic fens, and ditches.
Juncus dudleyi is a widespread species of rush native to North America, and introduced to northern South America, Japan, Great Britain and central Europe. Its diploid chromosome number is 2n=80.
Juncus stygius, called the bog rush and moor rush, is a species of flowering plant in the genus Juncus, with a high circumboreal distribution, never reaching further south than Switzerland, Korea and Upstate New York.
Juncus biglumis, called the two-flowered rush, is a species of flowering plant in the family Juncaceae, native to the subarctic and subalpine Northern Hemisphere. It has three divergent genetic lineages that may represent cryptic species.
Juncus triglumis, called the three-flowered rush, is a species of flowering plant in the genus Juncus, native to the subarctic and subalpine Northern Hemisphere. It is typically found in calcareous tundra habitats and arcto-alpine fens. It is often found in association with Carex atrofusca and Carex bicolor in the so-called Caricion bicolori-atrofuscae alliance.
Juncus canadensis, called the Canadian rush, is a species of flowering plant in the genus Juncus, native to central and eastern Canada and the central and eastern United States, and introduced to Oregon, New Zealand, and the Low Countries in Europe. It is an obligate wetland species.
Juncus subulatus, called the Somerset rush, is a species of flowering plant in the genus Juncus, with a Mediterranean, Middle Eastern and Central Asian distribution, and introduced to Great Britain. It typically grows in salt marshes.
