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] |
Phalaris Aquatica
''Phalaris aquatica'', known by the common names bulbous canary-grass and Harding grass, is a species of grass in the genus ''Phalaris'' of the family Poaceae. Description It is an erect, waist-high, stout perennial bunch grass, with grayish to bluish green leaves. Flowering heads are dense, spike-like, and usually long. It is slow to develop from seed, but can form large bunches after several years. ''Phalaris arundinacea'' (reed canary grass) differs from Harding grass in having more distinct rhizomes, and an inflorescence that is compact at first but becomes more open as the branches spread. Hybrids of Harding grass and reed canary grass have been produced. Varieties include 'AQ1', 'Uneta', and 'Australis'. ''P. aquatica'' is a quick-growing grass which incorporates and utilises soil nitrogen rapidly. Geography ''Phalaris aquatica'' originated from Southern Europe and the Caucasus. It is naturalized in South Africa, Australia, New Zealand and the USA. Although very recent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalaris Platensis
Phalaris ( el, Φάλαρις) was the tyrant of Akragas (now Agrigento) in Sicily, from approximately 570 to 554 BC. History Phalaris was renowned for his excessive cruelty. Among his alleged atrocities is cannibalism: he was said to have eaten suckling babies. Phalaris was entrusted with the building of the temple of Zeus Atabyrius in the citadel and took advantage of his position to make himself despot. Under his rule, Agrigentum seemed to have attained considerable prosperity. He supplied the city with water, adorned it with fine buildings, and strengthened it with walls. On the northern coast of the island, the people of Himera elected him general with absolute power, in spite of the warnings of the poet Stesichorus. According to the ''Suda'' he succeeded in making himself master of the whole of the island. He was at last overthrown in a general uprising headed by Telemachus, the ancestor of Theron of Acragas (tyrant c. 488–472 BC), and burned in his own brazen bull. ...

Eastern Agricultural Complex
The Eastern Agricultural Complex in the woodlands of eastern North America was one of about 10 independent centers of plant domestication in the pre-historic world. Incipient agriculture dates back to about 5300 BCE. By about 1800 BCE the Native Americans of the woodlands were cultivating several species of food plants, thus beginning a transition from a hunter-gatherer economy to agriculture. After 200 BCE when maize from Mexico was introduced to the Eastern Woodlands, the Native Americans of the eastern United States and adjacent Canada slowly changed from growing local indigenous plants to a maize-based agricultural economy. The cultivation of local indigenous plants other than squash and sunflower declined and was eventually abandoned. The formerly domesticated plants returned to their wild forms. The first four plants known to have been domesticated at the Riverton Site in Illinois in 1800 BCE were goosefoot (''Chenopodium berlandieri''), sunflower ('' Helianthus annuus v ...

Phalaris Canariensis
Canary grass is a plant, ''Phalaris canariensis'', belonging to the family Poaceae. Originally a native of the Mediterranean region, it is now grown commercially in several parts of the world for birdseed. Description ''Phalaris canariensis'' resembles ''Phalaris arundinacea'' (reed canary grass), a perennial forage crop and a wild grass. Although heads of both crops are panicles, ''Phalaris canariensis'' heads resemble club wheat. This large, coarse grass has erect, hairless stems, usually from tall. The ligule is prominent and membranous, long and rounded at the apex. The gradually tapering leaf blades are long, wide, flat, and often harsh on both surfaces. The compact panicles are erect or sometimes slightly spreading and range from long with branches long. Single flowers occur in dense clusters in May to mid-June or August. Inflorescences are green or slightly purple at first, then become tan. Seeds The seeds are shiny brown. The seed is used as bird food and is ...
