Juncus Roemerianus
''Juncus roemerianus'' is a species of flowering plant in the rush family known by the common names black rush, needlerush, and black needlerush. It is native to North America, where its main distribution lies along the coastline of the southeastern United States, including the Gulf Coast. It occurs from New Jersey to Texas, with outlying populations in Connecticut, New York, Mexico, and certain Caribbean islands.Uchytil, Ronald J. (1992)''Juncus roemerianus''.In: Fire Effects Information System, nline U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. Retrieved 1-2-2012. Description This rush is a perennial plant forming tufts of rough, rigid stems and leaves. It is gray-green in color. The plant may appear to be leafless at first glance, but what look like sharp-pointed stems are actually stiff leaves rolled tightly to form pointed cylinders. The true stems are tipped with inflorescences. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Juncaceae
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. Description The leaves are evergreen and well-developed in a basal aggregation on an erect stem. They are alternate and tristichous (i.e., with three rows of leaves up the stem, each row of leaves arising one-third of the way around the stem from the previous leaf). Only in the genus '' Distichia'' are the leaves distichous. The rushes of the genus ''Juncus'' have flat, hairless leaves or cylindrical leaves. The leaves of the wood-rushes of the genus ''Luzula' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetative Reproduction
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. While m ...

Brackish Marsh
Brackish marshes develop from salt marshes where a significant freshwater influx dilutes the seawater to brackish levels of salinity. This commonly happens upstream from salt marshes by estuaries of coastal rivers or near the mouths of coastal rivers with heavy freshwater discharges in the conditions of low tidal ranges. Characteristics The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. Marshes are also characterised by low-growing vegetation and bare mud or sand flats. Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. The salinity levels also change with the tides, decreasing at low tide and increasing at high tide as ocean water feeds farther upriver. Biodiversity In terms of biodiversity, a brackish marsh serves a unique ecological niche. Its vegetation is a byproduct of its salinity levels. High salinity serves as an evolutionary barrier for m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scirpus Robustus
''Bolboschoenus robustus'' is a species of flowering plant in the sedge family.

The plant reproduces sexually by seed and colonie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salicornia
''Salicornia'' is a genus of succulent, halophytic (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. ''Salicornia'' species are native to North America, Europe, Central Asia, and southern Africa. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in ''Salicornia''. To French speakers in Atlantic Canada, they are known colloquially as ''titines de souris'' ('mouse tits'). The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus as sea beans, samphire greens or sea asparagus. Description The ''Salicornia'' species are small annual herbs. They grow prostrate to erect, their simple or branched stems are succulent, hairless, and appear to be jointed. The opposite leaves are strongly reduced to sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distichlis Spicata
''Distichlis spicata'' is a species of grass known by several common names, including seashore saltgrass, inland saltgrass, and desert saltgrass. This grass is native to the Americas, where it is widespread. It can be found on other continents as well, where it is naturalized. It is extremely salt tolerant.Mojave Desert Wildflowers, Pam MacKay, 2nd ed. 2013, p 284 Distribution and habitat ''Distichlis spicata'' thrives along coastlines and on salt flats and disturbed soils, as well as forest, woodland, montane, and desert scrub habitats. It can form dense monotypic stands, and it often grows in clonal colonies. Non-clonal populations tend to be skewed toward a majority of one sex or the other. The grass forms sod with its hearty root system. Its rhizomes have sharp points which allow it to penetrate hard soils and aerenchymous tissues, which allow it to grow underwater and in mud. This plant grows easily in salty and alkaline soils, excreting salts from its tissues via salt g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spartina Patens
''Sporobolus pumilus'', the saltmeadow cordgrass, also known as salt hay, is a species of cordgrass native to the Atlantic coast of the Americas, from Newfoundland south along the eastern United States to the Caribbean and north-eastern Mexico. It was reclassified after a taxonomic revision in 2014, but the older name, ''Spartina patens'', may still be found in use. It can be found in marshlands in other areas of the world as an introduced species and often a harmful noxious weed or invasive species. It is a hay-like grass found in the upper areas of brackish coastal salt marshes. It is a slender and wiry plant that grows in thick mats 30–60 cm high, green in spring and summer, and turns light brown in late fall and winter. The stems are wispy and hollow, and the leaves roll inward and appear round. Because its stems are weak, the wind and water action can bend the grass, creating the appearance of a field of tufts and cowlicks. Like its relative smooth cordgrass, saltmead ...

Mississippi
Mississippi () is a state in the Southeastern region of the United States, bordered to the north by Tennessee; to the east by Alabama; to the south by the Gulf of Mexico; to the southwest by Louisiana; and to the northwest by Arkansas. Mississippi's western boundary is largely defined by the Mississippi River. Mississippi is the 32nd largest and 35th-most populous of the 50 U.S. states and has the lowest per-capita income in the United States. Jackson is both the state's capital and largest city. Greater Jackson is the state's most populous metropolitan area, with a population of 591,978 in 2020. On December 10, 1817, Mississippi became the 20th state admitted to the Union. By 1860, Mississippi was the nation's top cotton-producing state and slaves accounted for 55% of the state population. Mississippi declared its secession from the Union on January 9, 1861, and was one of the seven original Confederate States, which constituted the largest slaveholding states in t ...

Spartina Alterniflora
''Sporobolus alterniflorus'', or synonymously known as ''Spartina alterniflora'', the smooth cordgrass, saltmarsh cordgrass, or salt-water cordgrass, is a perennial deciduous grass which is found in intertidal wetlands, especially estuarine salt marshes. It has been reclassified as ''Sporobolus alterniflorus'' after a taxonomic revision in 2014, but it is still common to see ''Spartina alterniflora'' and in 2019 an interdisciplinary team of experts coauthored a report published in the journal ''Ecology'' supporting ''Spartina'' as a genus. It grows tall and has smooth, hollow stems that bear leaves up to long and wide at their base, which are sharply tapered and bend down at their tips. Like its relative saltmeadow cordgrass ''S. patens'', it produces flowers and seeds on only one side of the stalk. The flowers are a yellowish-green, turning brown by the winter. It has rhizoidal roots, which, when broken off, can result in vegetative asexual growth. The roots are an important f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
