Panicum Flexile
''Panicum flexile'', commonly called wiry panicgrass, is a species of flowering plant in the grass family ( Poaceae). It is primarily native to eastern to North America, where it has a scattered and localized distribution. It is typically found in mafic or calcareous open areas, both wet and dry, particularly associated with limestone Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms whe .... ''Panicum flexile'' is a rather delicate annual grass. It can be distinguished from similar-looking ''Panicum'' by its long-acuminate spikelets arranged in a slender, elongated panicle.

Frank Lamson-Scribner
Frank Lamson-Scribner (April 19, 1851 – February 22, 1938) was an American botanist and pioneering plant pathologist. He was the first United States Department of Agriculture scientist hired to study plant disease in economic plants and first USDA agrostologist. Early life Franklin Pierce Lamson was born April 19, 1851, in Cambridgeport, Massachusetts. His parents Joseph Sanborn and Eunice Ellen (Winslow) Lamson died when he was 3 years old and he was adopted by the Virgil Scribner family near Manchester, Maine. He received preparatory education at Hebron Academy, Kents Hill School, and Coburn Classical Institute and graduated from University of Maine, Maine State College of Agriculture and Mechanic Arts in 1873. Career Lamson-Scribner taught botany in Maine high schools, before becoming an officer with Girard College in 1877. He was the botanist for the Northern Transcontinental Survey and completed an inventory of grasses and forages in Montana in the summer of 1883. In May 1885 ...

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] |
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, ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Research Institute Of Texas
The Botanical Research Institute of Texas (BRIT) is a botanical research institute located in Fort Worth, Texas, United States. It was established in 1987 for the herbarium and botanical library collections of Lloyd H. Shinners from Southern Methodist University but has subsequently expanded substantially. BRIT focuses on plant taxonomy, conservation and knowledge sharing for both scientists and the general public History The Botanical Research Institute of Texas was founded in 1987 around the herbarium and library from the Southern Methodist University that been substantially expanded by their final curator, Lloyd Herbert Shinners. It was located in a re-purposed warehouse in the main business and commercial area of Fort Worth. In spring 2011, BRIT moved into new buildings adjacent to the Fort Worth Botanic Garden that dates from 1934. The buildings were designed by Hugh Hardy of H3 Hardy Collaboration Architecture and have a LEED-NC platinum rating from the U.S. Green Building ...

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).
