Panicum
''Panicum'' (panicgrass) is a large genus of about 450 species of grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to tall. The flowers are produced in a well-developed panicle often up to in length with numerous seeds, which are long and broad. The fruits are developed from a two-flowered spikelet. Only the upper floret of each spikelet is fertile; the lower floret is sterile or staminate. Both glumes are present and well developed. Australia has 29 native and 9 introduced species of ''Panicum''. Well-known ''Panicum'' species include ''Panicum miliaceum'' (proso millet) and ''Panicum virgatum'' (switchgrass).

Panicum Dichotomiflorum
''Panicum dichotomiflorum'', known by the common names fall panicgrass, autumn millet (Britain and Ireland), and fall panicum is a species of Poaceae "true grass". It is native to much of the eastern United States and parts of Canada, and it can be found in the Western United States through California. It may be an introduced species in some western climates. It grows in many types of habitat, including disturbed areas and chaparral habitats.

Panicum Virgatum
''Panicum virgatum'', commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55th parallel north, 55°N latitude in Canada southwards into the United States and Mexico. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation projects, fiber, electricity, heat production, for biosequestration of atmospheric carbon dioxide, and more recently as a biomass crop for ethanol and butanol. Other common names for switchgrass include tall panic grass, Wobsqua grass, blackbent, tall prairiegrass, wild Agrostis, redtop, thatchgrass, and Virginia switchgrass.

Panicum Decompositum
''Panicum decompositum'', known by the common names native millet, native panic, Australian millet, papa grass, and umbrella grass, is a species of perennial grass native to the inland of Australia. It occurs in every mainland state. The seeds can be cultivated to produce flour typically used in Aboriginal bushfood. The species is also considered to have relatively high palatability by livestock, making it suitable for grazing pastures. Description Native millet is specifically a C4 tussock forming perennial with glabrous blue-green blade-like leaves with a pale line running down the middle on the front of the leaves and a protruding spine, known as the keel, at the back of the leaves. The grass can grow up to 145cm tall with seed heads that can grow up to approximately 40cm in length. Native millet is hermaphroditic, which means it contains both the male and female reproductive organs in the same flower. The seed head has an open panicle structure which consists of multipl ...

Panicum Hillmanii
''Panicum hillmanii'', commonly known as Hillmann's panicgrass, is a grass from genus ''Panicum'' native to Southwestern United States. It has been introduced to many other areas, notably including southern Australia where it became widespread, and several parts of Europe. Description ''Panicum hillmannii'' is a perennial grass that resembles the related '' P. capillare'' (hairy panic) in habitat and appearance. It is distinguished by slightly stiffer panicles, firmer foliage, the rachilla shortly developed between the upper and lower glumes, the sterile floret which has the palea developed; and larger darker fertile lemma (up to 2mm long) with a prominent crescent-shaped scar at its base. Distribution and habitat ''Panicum hillmannii'' is native to Southwest United States. It was introduced to Australia in the early 1900s, and has spread across South Australia, Victoria, New South Wales and Tasmania, sharing the habitat with related native witchgrass ('' P. effusum'').

Panicum Miliaceum
''Panicum miliaceum'' is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. The crop is extensively cultivated in China, India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the United States, where about half a million acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet ( sh-Latn-Cyrl, separator=/, proso, просо, cs, proso, pl, proso, russian: просо). Proso millet is a relative of foxtail millet, pearl millet, maize, and sorghum within the gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panicum Lycopodioides
''Panicum lycopodioides,'' common name false club-moss panic grass or (in French) panic faux-lycopode, is endemic to the French island of Réunion in the Indian Ocean. It is found at high altitudes on the island, at elevations over 2000 m (6700 feet). The highest point on the island is Piton des Neiges, 3069 m (10,230 feet). The plant requires full sun-light and a cold climate. The specific epithet "''lycopodioides''" means "similar to ''Lycopodium''" in reference to the plant's general habitus superficially resembling certain species of club-moss. Stems grow horizontally, branching frequently, thus forming mats pressed against the ground. Leaves are small, pressed against the stem like the scales of ''Lycopodium ''Lycopodium'' (from Greek ''lykos'', wolf and ''podion'', diminutive of ''pous'', foot) is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae.
