Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Tropical Low Shrublands
The Hawaiian tropical low shrublands are a tropical savanna ecoregion in the Hawaiian Islands. Geography These shrublands cover an area of in the leeward lowlands of the main islands and most of the smaller islands, not including the Northwestern Hawaiian Islands which form an ecoregion of their own. Flora The ecoregion includes both grasslands and mixed shrublands. Kāwelu (''Eragrostis variabilis''), mauu akiaki (''Fimbristylis cymosa''), akiaki (''Sporobolus virginicus''), and ''Lepturus repens'' are common grassland plants. Shrublands are dominated by ilima (''Sida fallax''), aalii (''Dodonaea viscosa''), naupaka ('' Scaevola'' spp.), hinahina kū kahakai ( ''Heliotropium anomalum'' var. ''argenteum''), kīpūkai ('' Heliotropium curassavicum''), mao (''Gossypium tomentosum''), akoko (''Euphorbia'' spp.), āheahea (''Chenopodium oahuense''), naio (''Myoporum sandwicense''), kolokolo kahakai (''Vitex rotundifolia''), and pūkiawe (''Styphelia tameiameiae'').

Plants Described In 1824
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Endemic Flora Of Hawaii
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capparis
''Capparis'' is a flowering plant genus, comprising around 250 species in the family Capparaceae which is included in the Brassicaceae in the unrevised APG II system. These plants are shrubs or lianas and are collectively known as caper shrubs or caperbushes. ''Capparis'' species occur over a wide range of habitat in the subtropical and tropical zones. Plant description The leaves are simple, entire and rarely reduced. Flowers are bisexual, bracteates, axillary or supra-axillary, solitary or in rows, in racemes or umbels. Sepals and petals are 4 in number and are free. Stamens are many, ovary on a gynophore, 1-celled. Fruit is a berry, globose or ellipsoid. ''C. zeylanica'' L. ''C. zeylanica'' L. is a climbing or straggling shrub with tomentose branches. Branches are armed with recurved stipular spines. It grows naturally along the hedges. Leaves are ovate-elliptic.

United States Botanic Garden
The United States Botanic Garden (USBG) is a botanical garden on the grounds of the United States Capitol in Washington, D.C., near Garfield Circle. The Botanic Garden is supervised by the United States Congress, Congress through the Architect of the Capitol, who is responsible for maintaining the grounds of the United States Capitol. The USBG is open every day of the year, including federal holidays. It is the oldest continually-operating botanic garden in the United States. History The Columbian Institute for the Promotion of Arts and Sciences in Washington, DC first suggested the creation of the Botanic Garden in 1816. In 1820 it was given land by an act of Congress. The land was located west of the Capitol extending from First Street to Third Street between Pennsylvania and Maryland Avenues. The facility ceased to operate in 1837 when the society stopped holding meetings. However it was re-instituted in 1842 when the Wilkes expedition of the South Seas brought back a co ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Laysan
Laysan (; haw, italics=no, Kauō ), located northwest of Honolulu at , is one of the Northwestern Hawaiian Islands. It comprises one land mass of , about in size. It is an atoll of sorts, although the land completely surrounds a shallow central lake some above sea level that has a salinity approximately three times greater than the ocean. Laysan's Hawaiian name, Kauō, means ''egg''. Geology Laysan is the second largest single landmass in the Northwestern Hawaiian Islands, after Sand Island at Midway Atoll. Laysan was created by coral growth and geologic upshift. The fringing reefs surrounding the island cover about . Lake Laysan, the , brown, hypersaline lake in the island's interior, has varied in depth over the decades. In the 1860s, the lake was at most deep, but by the 1920s it averaged deep, because of the buildup of sand that had been blown away in sandstorms. The best way to find fresh water on Laysan is to observe where the finches are drinking; the fresh wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capparaceae
The Capparaceae (or Capparidaceae), commonly known as the caper family, are a family of plants in the order Brassicales. As currently circumscribed, the family contains 33 genera and about 700 species. The largest genera are '' Capparis'' (about 150 species), '' Maerua'' (about 100 species), '' Boscia'' (37 species) and ''Cadaba'' (30 species). Taxonomy The Capparaceae have long been considered closely related to and have often been included in the Brassicaceae, the mustard family (APG, 1998), in part because both groups produce glucosinolate (mustard oil) compounds. Subsequent molecular studies support Capparaceae'' sensu stricto'' as paraphyletic with respect to the Brassicaceae. However ''Cleome'' and several related genera are more closely related to members of the Brassicaceae than to the other Capparaceae. These genera are now either placed in the Brassicaceae (as subfamily Clemoideae) or segregated into the Cleomaceae. Several more genera of the traditional Capparaceae ar ...

Pearl And Hermes Atoll
The Pearl and Hermes Atoll ( haw, Holoikauaua), also known as Pearl and Hermes Reef, is part of the Northwestern Hawaiian Islands, a group of small islands and atolls that form the farthest northwest portion of the Hawaiian island chain. The atoll consists of a variable number of flat and sandy islets, typically between five and seven. More were noted in historical sources but have since been lost to erosion and rising sea levels. The atoll is named after ''Pearl'' and , a pair of English whaleships that wrecked there in 1822. It has been the site of at least eight known shipwrecks, including the Japanese ''Wiji Maru'', SS ''Quartette'', and most recently the M/V ''Casitas'', which ran aground on the reef in 2005. The atoll is an important habitat for seabirds, marine life, and invertebrate species. Twenty-two bird species nest and breed on the islands, including twenty percent of the world's population of black-footed albatrosses. The atoll has historically been included w ...

Midway Atoll
Midway Atoll (colloquial: Midway Islands; haw, Kauihelani, translation=the backbone of heaven; haw, Pihemanu, translation=the loud din of birds, label=none) is a atoll in the North Pacific Ocean. Midway Atoll is an insular area of the United States and is an unorganized and unincorporated territory. The largest island is Sand Island, which has housing and an airstrip. Immediately to the east of Sand Island across the narrow Brooks Channel is Eastern Island, which is uninhabited and no longer has any facilities. Forming a rough, incomplete circle around the two main islands and creating Midway Lagoon is Spit Island, a narrow reef. Roughly equidistant between North America and Asia, Midway is the only island in the Hawaiian Archipelago that is not part of the state of Hawaii. Unlike the other Hawaiian islands, Midway observes Samoa Time ( UTC−11:00, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the Hawaii–Aleutian Time Zone ...
