Poa Alpina
''Poa alpina'', commonly known as alpine meadow-grass or alpine bluegrass, is a species of grass with a primarily holarctic distribution. It is noted for being pseudoviviparous: in place of seeds, it sometimes reproduces asexually, creating new plantlets in the spikelets. References alpina Alpina Burkard Bovensiepen GmbH & Co.

Fungi Described In 1863
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Poa Nemoralis
''Poa nemoralis'', the wood bluegrass, is a perennial plant in the family Poaceae. The late-growing grass is fairly nutritious for livestock, which feed on it in the autumn, and it is used as a lawn grass for shady situations. Description It forms loose tufts, and is of a more delicate, slender appearance than other meadow grasses. It is slightly creeping. The leaves are narrow, tapering to a point. The ligules are short (0.5 mm). The stem is slender, high. The panicle is slender, loose and branched. The spikelets are few and egg shaped. They have one to five flowers. This grass is in flower from June to August in the Northern Hemisphere. It can produce asexual seeds by means of apomixis and can also reproduce vegetatively. Because of the characteristic lamina, similar to a stretched out arm, it is sometimes called "Wegweisergras" (signpost grass) in Germany. Distribution and habitat Wood bluegrass is native to Europe, where its range extends from Portugal to Bulgar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poa Glauca
''Poa glauca'' is a species of grass known by the common names glaucous bluegrass, glaucous meadow-grass and white bluegrass. It has a circumboreal distribution, occurring throughout the northern regions of the Northern Hemisphere. It is also known from Patagonia. It is a common grass, occurring in Arctic and alpine climates and other areas. It can be found throughout the Canadian Arctic Archipelago in many types of habitat, including disturbed and barren areas. This is a perennial bunchgrass growing small, dense clumps of waxy leaves and stems up to about 80 centimeters in maximum height, but often remaining dwarfed, no more than 10 centimeters tall. The 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.

Phleum Pratense
Timothy (''Phleum pratense'') is an abundant perennial grass native to most of Europe except for the Mediterranean region. It is also known as timothy-grass, meadow cat's-tail or common cat's tail. It is a member of the genus '' Phleum'', consisting of about 15 species of annual and perennial grasses. It is probably named after Timothy Hanson, an American farmer and agriculturalist said to have introduced it from New England to the southern states in the early 18th century. Upon his recommendation it became a major source of hay and cattle fodder to British farmers in the mid-18th century. Timothy can be confused with meadow foxtail (''Alopecurus pratensis'') or purple-stem cat's-tail (''Phleum phleoides''). Description Timothy grows to tall, with leaves up to long and broad. The leaves are hairless, rolled rather than folded, and the lower sheaths turn dark brown. It has no stolons or rhizomes, and no auricles. The flowerhead is long and broad, with densely pac ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milium Effusum
''Milium effusum'', the American milletgrass or wood millet, is a species of flowering plant in the grass family Poaceae, native to damp forests of the Holarctic Kingdom. The Latin specific epithet ''effusum'' means "spreading loosely". Habitat ''Milium effusum'' inhabits damp, deciduous woods and shaded banks, where it grows on winter-wet, calcareous to mildly acidic clay and loam soils, and also over rocks in western Scotland. Distribution It can be found in the northern United States and Canada, and Europe, including Britain but excluding the Mediterranean, east to Siberia and the Himalayas. Cultivation The yellow-leaved cultivar 'Aureum', known as Bowles' golden grass, is cultivated as an ornamental garden plant, and in the UK has won the Royal Horticultural Society’s Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS).
