Scirpus Atrovirens
''Scirpus atrovirens'', known as dark-green bulrush, is a perennial sedge native to wetlands of eastern Canada and the United States. It is sometimes called dark green bulsedge, black bulrush, or green bulrush. It was first formally named by Carl Ludwig Willdenow in 1809. ''Scirpus atrovirens'' grows in a wide variety of wetland habitats, typically in sunny areas rather than shady. It can be found in wet meadows and shrubby thickets, openings in swamps, marshes, shorelines, as well as roadside ditches. The plant can grow up to five feet tall, and thrives in hardiness zones A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most wide ... 3–9. It is closely related to '' Scirpus hattorianus'' and '' Scirpus georgianus'', with mature fruits necessary for accurate identification. References ...

Nahant Marsh
Nahant is a town in Essex County, Massachusetts, United States. The population was 3,334 at the 2020 census, which makes it the smallest municipality by population in Essex County. With just of land area, it is the smallest municipality by area in the state. It is primarily a residential community. The town is situated on peninsula consisting of two near-islands (known as "Little Nahant" and "Big Nahant" respectively) connected to the mainland by a narrow sandy isthmus traversed by a single causeway known as "Nahant Road". Numerous tourist beaches line the shores, with the most popular being the so-called "Long Beach" and "Short Beach" along the eastern side of the causeway. History The area around Nahant was inhabited for thousands of years prior to European colonization of the Americas, but little is known of this period until European records began to document the area in the early 1600s. At that time, the seat of "Sagamore James" of the Naumkeag, known in his own tongue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scott County, Iowa
Scott County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 174,669, making it the third-most populous county in Iowa. The county seat is Davenport. Scott County is included in the Davenport– Moline- Rock Island, IA– IL Metropolitan Statistical Area. History The first American settlement in the area now known as Scott County was Clark's Ferry or Clark's Landing (now Buffalo) in 1833. Other early towns included Davenport (now the county seat and largest city) and the town of Rockingham (which ceased to exist in 1847). The area was fully surveyed in 1837, and the county was established by the Wisconsin territorial legislature in that same year. Scott County is named for General Winfield Scott, who was the presiding officer at the signing of the peace treaty ending the Black Hawk War. By 1900 the population of the county was 51,500, and by 1950 it was over 100,000. Scott County now comprises part of the Quad City region, which ...

Carl Ludwig Willdenow
Carl Ludwig Willdenow (22 August 1765 – 10 July 1812) was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology. Biography Willdenow was born in Berlin and studied medicine and botany at the University of Halle. After studying pharmaceutics at Wieglieb College, Langensalza and in medicine at Halle, he returned to Berlin to work at his father's pharmacy located in the Unter den Linden. His early interest in botany was kindled by his uncle J. G. Gleditsch and he started a herbarium collection in his teenage years. In 1794 he became a member of the Berlin Academy of Sciences. He was a director of the Botanical garden of Berlin from 1801 until his death ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus '' Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Scirpus Hattorianus
''Scirpus'' is a genus of grass-like species in the sedge family Cyperaceae many with the common names club-rush, wood club-rush or bulrush (see also bulrush for other plant genera so-named). They mostly inhabit wetlands and damp locations. Taxonomy The taxonomy of the genus is complex, and under review by botanists. Recent studies by taxonomists of the Cyperaceae have resulted in the creation of several new genera, including the genera ''Schoenoplectus'' and ''Bolboschoenus''; others (including ''Blysmus'', '' Isolepis'', '' Nomochloa'', and ''Scirpoides'') have also been used. At one point this genus held almost 300 species, but many of the species once assigned to it have now been reassigned, and it now holds an estimated 120 species. Description ''Scirpus'' are rhizomatous perennial herbs, with 3-angled stems and flat grass-like leaves. The flowers are in clusters of small spikelets, often brown or greenish brown. Some species (e.g. ''S. lacustris'') can reach a height of 3 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scirpus Georgianus
''Scirpus georgianus'', or Georgia bulrush, is a flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms.
