Phalaris Lemmonii
''Phalaris lemmonii'' is an uncommon species of grass known by the common name Lemmon's canarygrass. It is endemic to California, where it can be found in coastal and inland mountain ranges and the Central Valley. Description It grows mainly in moist areas. It is an annual grass reaching maximum heights between 1.3 and 1.5 meters. The cylindrical inflorescence An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches.

George Vasey (botanist)
George Vasey (February 28, 1822 – March 3, 1893) was an English-born American botanist who collected a lot in Illinois before integrating the United States Department of Agriculture (USDA), where he became Chief Botanist and curator of the greatly expanded National Herbarium. Biography George Vasey was born in 1822 near Scarborough, England, the fourth of ten children. His family emigrated to the United States the next year, and they established in Oriskany, New York. He left school at 12 to take a job as a store clerk. He took interest in botany after borrowing and, since he could not afford the volume, manually copying a book on the subject. This interest was later encouraged after a chance encounter with Peter D. Knieskern, another naturalist who allowed Vasey to begin writing to various other botanists. Until 1870 he would maintain an extensive correspondence and collect a great many specimens both in Oneida County and later McHenry County, but did not publish material 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, ...

Endemism
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] |

Central Valley (California)
The Central Valley is a broad, elongated, flat valley that dominates the interior of California. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast of the state. It covers approximately , about 11% of California's land area. The valley is bounded by the Coast Ranges The Pacific Coast Ranges (officially gazetted as the Pacific Mountain System in the United States) are the series of mountain ranges that stretch along the West Coast of North America from Alaska south to Northern and Central Mexico.

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Phalaris (plant)
''Phalaris'' is a genus of grasses. Various species of ''Phalaris'' grow on every continent except Antarctica. They can be found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry places. ''P. arundinacea'' and ''P. aquatica'' are sometimes invasive species in wetlands. Alkaloids Some ''Phalaris'' species contain gramine, which, in sheep and to a lesser extent in cattle, is toxic and can cause brain damage, other organ damage, central nervous system damage, and death. ''Phalaris arundinacea'', ''Phalaris aquatica'', and '' Phalaris brachystachys'' are known to contain the alkaloids DMT, 5-MeO-DMT, and 5-OH-DMT (bufotenin). Some research has been done into the variability of alkaloids in the ''Phalaris'' grasses. Strains with high levels of alkaloids are best avoided in locations with grazing cattle and sheep, due to potential toxicity. Such high-alkaloid strains include ''Phalaris aquatica AQ-1'' and the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
