Yellow Flag Iris
''Iris pseudacorus'', the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet ''pseudacorus'' means "false acorus", referring to the similarity of its leaves to those of ''Acorus calamus'' (sweet flag), as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. Description This herbaceous flowering perennial plant grows to , or a rare tall, with erect leaves up to long and broad. The flowers are bright yellow, across, with the typical iris form. The fruit is a dry capsule long, containing numerous pale brown seeds. ''I. pseudacorus'' grows best in very wet conditions, and is common in wetlands, where it tolerates submersion, low pH, and anoxic soils. The plant spreads quickly, by both rhizome and water-dispersed seed. It fills a similar niche to that of ''Typha'' and often grows with it, thou ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris Foetidissima
''Iris foetidissima'', the stinking iris,Richard Fitter, Alastair Fitter and Marjorie Blamey gladdon, Gladwin iris, roast-beef plant, or stinking gladwin, is a species of flowering plant in the family Iridaceae, found in open woodland, hedgebanks and on sea-cliffs. Its natural range is Western Europe, including England (south of Durham) and also Ireland, and from France south and east to N. Africa, Italy and Greece. It is one of two iris species native to Britain, the other being the yellow iris (''Iris pseudacorus''). It has tufts of dark green leaves. Its flowers are usually of a dull, leaden-blue colour, or dull buff-yellow tinged with blue. The petals have delicate veining. It blooms between June and July, but the flowers only last a day or so. The green seed capsules, which remain attached to the plant throughout the winter, are long; and the seeds are scarlet. It is known as "stinking" because some people find the smell of its leaves unpleasant when crushed or bruise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware
Delaware ( ) is a U.S. state, state in the Mid-Atlantic (United States), Mid-Atlantic and South Atlantic states, South Atlantic regions of the United States. It borders Maryland to its south and west, Pennsylvania to its north, New Jersey to its northeast, and the Atlantic Ocean to its east. The state's name derives from the adjacent Delaware Bay, which in turn was named after Thomas West, 3rd Baron De La Warr, an English nobleman and the Colony of Virginia's first colonial-era governor. Delaware occupies the northeastern portion of the Delmarva Peninsula, and some islands and territory within the Delaware River. It is the List of U.S. states and territories by area, second-smallest and List of U.S. states and territories by population, sixth-least populous state, but also the List of U.S. states and territories by population density, sixth-most densely populated. Delaware's List of municipalities in Delaware, most populous city is Wilmington, Delaware, Wilmington, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aquatic Plant
Aquatic plants, also referred to as hydrophytes, are vascular plants and Non-vascular plant, non-vascular plants that have adapted to live in aquatic ecosystem, aquatic environments (marine ecosystem, saltwater or freshwater ecosystem, freshwater). In lakes, rivers and wetlands, aquatic vegetations provide cover for aquatic animals such as fish, amphibians and aquatic insects, create substrate (marine biology), substrate for benthic invertebrates, produce oxygen via photosynthesis, and serve as food for some herbivorous wildlife. Familiar examples of aquatic plants include Nymphaeaceae, waterlily, Nelumbo, lotus, duckweeds, mosquito fern, floating heart, water milfoils, Hippuris, mare's tail, water lettuce, water hyacinth, and algae. Aquatic plants require special adaptation (biology), adaptations for prolonged inundation in water, and for buoyancy, floating at the water surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasive Species
An invasive species is an introduced species that harms its new environment. Invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food web. Since the 20th century, invasive species have become serious economic, social, and environmental threats worldwide. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of invasion. For millennia, humans have served as both accidental and deliberate dispersal agents, beginning with their earliest migrations, accelerating in the Age of Discovery, and accelerating again with the spread of international trade. Notable invasive plant species include the kudzu vine, giant hogweed (''Heracleum mantegazzianum''), Japanese knotw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
