Cenchrus Agrimonioides
''Cenchrus agrimonioides'' is a rare species of grass in the family Poaceae that is endemic to the Hawaiian Islands. Its common names include KÄmanomano and agrimony sandbur. It was formerly distributed throughout the major islands but today it is nearly limited to Oahu. KÄmanomano inhabits dry to moist forests and lava plains. It is threatened by competition with non-native plants, predation by ungulates, and wildfire. When this plant became a federally listed endangered species of the United States in 1996 there were fewer than 100 individuals remaining.USFWS''Cenchrus agrimonioides'' Five Year Review.July 21, 2009. More recent counts revealed 181 wild individuals on Oahu and over 300 more which have been planted to augment the populations. This plant is nearly restricted to the island of Oahu, but there are a few individuals known on Maui. A few patches of the grass have been planted on Kahoolawe, as well.

Carl Bernhard Von Trinius
Carl Bernhard von Trinius (6 March 1778, Eisleben – 12 March 1844, St. Petersburg) was a German-born botanist and physician. He studied medicine at several universities, earning his medical doctorate at the University of Göttingen in 1802. In 1808, after time spent as a physician in Hasenpoth, he served as a personal physician to Antoinette, Duchess of Württemberg (née Princess of Saxe-Coburg-Saalfeld) for the next 16 years. During this time period, he traveled extensively throughout Germany and Russia. In St. Petersburg, he became good friends to author Ernst Moritz Arndt. After the death of the duchess in 1824, he remained in St. Petersburg as an imperial physician, and along with a medical practice, he dealt with botanical concerns at the Academy of Sciences.biography @ |
Maui
The island of Maui (; Hawaiian: ) is the second-largest of the islands of the state of Hawaii at 727.2 square miles (1,883 km2) and is the 17th largest island in the United States. Maui is the largest of Maui County's four islands, which also includes Molokai, LÄnai, and unpopulated Kahoolawe. In 2020, Maui had a population of 168,307, the third-highest of the Hawaiian Islands, behind that of Oahu and Hawaii Island. Kahului is the largest census-designated place (CDP) on the island with a population of 26,337 , and is the commercial and financial hub of the island. Wailuku is the seat of Maui County and is the third-largest CDP . Other significant places include KÄ«hei (including Wailea and Makena in the Kihei Town CDP, the island's second-most-populated CDP), LÄhainÄ (including KÄanapali and Kapalua in the LÄhainÄ Town CDP), Makawao, Pukalani, PÄia, Kula, HaikÅ«, and HÄna.

Endangered Flora Of The United States
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1826
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 los ...

Cenchrus
''Cenchrus'' is a widespread genus of plants in the Poaceae, grass family. Its species are native to many countries in Asia, Africa, Australia, the Americas, and various oceanic islands. Common names include buffelgrasses, sandburs, and sand spur “sticky burâ€. Such names allude to the sharp, spine-covered bur, burrs characterizing the inflorescences of the members of the genus.

Seed Dispersal
In Spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. These modes are typically inferred based on adaptations, such as wings or fleshy fruit. However, this simplified view may ign ...

Northwestern Hawaiian Islands
The Northwestern Hawaiian Islands or Leeward Hawaiian Islands are a series of islands and atolls in the Hawaiian island chain located northwest (in some cases, far to the northwest) of the islands of Kauai and Niihau. Politically, they are all part of Honolulu County in the U.S. state of Hawaii, except Midway Atoll, which is a territory distinct from the State of Hawaii, and grouped as one of the United States Minor Outlying Islands. The United States Census Bureau defines this area, except Midway, as Census Tract 114.98 of Honolulu County. Its total land area is . All the islands except Nihoa are north of the Tropic of Cancer, making them the only islands in Hawaii that lie outside the tropics. The Northwestern or Leeward Hawaiian Islands include: *Nihoa (Moku Manu) at * Necker (Mokumanamana) at * French Frigate Shoals (KÄnemilohai) at *Gardner Pinnacles (PÅ«hÄhonu) at * Maro Reef (NalukÄkala) at * Laysan (KauÅ) at * Lisianski (PapaÄpoho) at * Pearl and Hermes Ato ...

Kahoolawe
Kahoolawe (Hawaiian: ), anglicized as Kahoolawe (), is the smallest of the eight main volcanic islands in the Hawaiian Islands. Kahoolawe is located about southwest of Maui and also southeast of LÄnaÊ»i, and it is long by wide, with a total land area of . The highest point on Kahoolawe is the crater of Lua Makika at the summit of Puu Moaulanui, which is about above sea level. Kahoolawe is relatively dry (average annual rainfall is less than ) because the island's low elevation fails to generate much orographic precipitation from the northeastern trade winds, and KahoÊ»olawe is located in the rain shadow of eastern Maui's volcano, HaleakalÄ. More than one quarter of Kahoolawe has been eroded down to saprolitic hardpan soil, largely on exposed surfaces near the summit. Kahoolawe has always been sparsely populated, due to its lack of fresh water. During World War II and the following decades, Kahoolawe was used as a training ground and bombing range by the Armed Forces of ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...
