Festuca Pratensis
''Festuca pratensis'', the meadow fescue, is a perennial species of grass, which is often used as an ornamental grass in gardens, and is also an important forage crop. It grows in meadows, roadsides, old pastures, and riversides on moist, rich soils, especially on loamy and heavy soils. It is a tall, tufted grass similar to the tall fescue, ''Festuca arundinacea''. Tall fescue differs by having minute hairs on the auricles. It can hybridise with ''Lolium perenne'' and ''Lolium multiflorum''. Description It is a perennial bunchgrass, (i.e. grows in tufts), which grows , flowering from June until August. The panicles are green to purplish. The spikelets have 5 to 14 flowers. It has a short, blunt ligule A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ... compared to other gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Hudson (botanist)
William Hudson FRS (1730 in Kendal – 23 May 1793) was a British botanist and apothecary based in London. His main work was ''Flora Anglica'', published in 1762. He was elected a fellow of the Royal Society in 1761. Life and work Hudson was born between 1730 and 1732 at the White Lion Inn, Kendal, which was kept by his father. He was educated at Kendal grammar school, Hudson was subsequently apprenticed to an apothecary in London. He obtained the prize for botany given by the Apothecaries' Company which was a copy of Ray's ''Synopsis''. However, he also paid attention to mollusca and insects and in Pennant's '' British Zoology'' he is mentioned as the discoverer of '' Trochus terrestris''. From 1757 to 1768 Hudson was resident sub-librarian of the British Museum, and his studies in the Sloane herbarium enabled him to adapt the Linnean nomenclature to the plants described by Ray far more accurately than did John Hill in his ''Flora Britannica'' of 1760. In 1761 Hudson w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Grass
Ornamental grasses are grasses grown as ornamental plants. Ornamental grasses are popular in many colder hardiness zones for their resilience to cold temperatures and aesthetic value throughout fall and winter seasons. Classifications Along with true grasses (Poaceae), several other families of grass-like plants are typically marketed as ornamental grasses. These include the sedges (Cyperaceae), rushes (Juncaceae), restios (Restionaceae), and cat-tails (Typhaceae). All are monocotyledons, typically with narrow leaves and parallel veins. Most are herbaceous perennials, though many are evergreen and some develop woody tissues. They bring striking linear form, texture, color, motion, and sound to the garden, throughout the year. Habits Almost all ornamental grasses are perennials, coming up in spring, from their roots, which have stored large quantities of energy, and in fall or winter go dormant. Some, notably bamboos, are evergreen, and a few are annuals. Many are bunch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ligule
A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm (Johnson grass, ''Sorghum halepense''), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (''Echinochloa crus-galli''). A ligule can also be defined as a membrane-like tissue or row of delicate hairs typically found in grasses at the junction of the leaf sheath and blade. The ...

Spikelet
A spikelet, in botany, describes the typical arrangement of the flowers of grasses, sedges and some other Monocots. Each spikelet has one or more florets. The spikelets are further grouped into panicles or spikes. The part of the spikelet that bears the florets is called the rachilla. In grasses In Poaceae, the grass family, a spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. Lemma Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panicle
A panicle is a much-branched inflorescence. (softcover ). Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth. This type of inflorescence is largely characteristic of grasses such as oat and crabgrass, as well as other plants such as pistachio and mamoncillo. Botanists use the term paniculate in two ways: "having a true panicle inflorescence" as well as "having an inflorescence with the form but not necessarily the structure of a panicle". Corymb A corymb may have a paniculate branching structure, with the lower flowers having longer pedicels than the upper, thus giving a flattish top superficially resembling an umbel. Many species in the subfamily Amygdaloideae, such as hawthorns and rowans, produce their flowers in corymbs. up'' Sorbus glabrescens'' corymb with fruit See ...

Bunchgrass
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens. Many species have long roots that may reach or more into the soil, which can aid slope stabilization, erosion control, and soil porosity for precipitation absorption. Also, their roots can reach moisture more deeply than other grasses and annual plants during seasonal or climatic droughts. The plants provide habitat and food for insects (including Lepidoptera), birds, small animals and larger herbivores, and support beneficial soil mycorrhiza. The leaves supply material, such as for basket weaving, for indigenous peoples and contemporary artists. Tussock and bunch grasses occur in almost any habitat ...

Lolium Multiflorum
''Lolium multiflorum'' (Italian rye-grass, annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. It is also grown as an ornamental grass. It readily naturalizes in temperate climates, and can become a noxious weed in arable areas and an invasive species in native habitats. It is a host plant to wheat yellow leaf virus in its native Europe. It is sometimes considered a subspecies of perennial ryegrass (''Lolium perenne''). It differs from ''L. perenne'' in its spikelet, which has a long bristle at the top, and its stem, which is round rather than folded. It can be mistaken for couch (''Elymus repens''), which has spikelets along the broad side of the stem rather than the edge. Other common names in English include Australian ryegrass, short rotation ryegrass, and Westerwolds ryegrass. It is also one of several species called d ...

Lolium Perenne
''Lolium perenne'', common name perennial ryegrass, English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world. Description The plant is a low-growing, tufted, hairless grass, with a bunching (or tillering) growth habit. The leaves are dark green, smooth and glossy on the lower surface, with untoothed parallel sides and prominent parallel veins on the upper surface. The leaves are folded lengthwise in bud (unlike the rolled leaves of Italian ryegrass, ''Lolium multiflorum'') with a strong central keel, giving a flattened appearance. The ligule is very short and truncated and often difficult to see. The small white auricles grip the stem at the base of the leaf blade. Leaf sheaths at the base are usually tinged pink and hairless. Stems grow up to 90 cm. The inflorescence is unbranched, with spikelets on alternating sides edgeways-on to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Festuca Arundinacea
''Festuca arundinacea'' ( syn., ''Schedonorus arundinaceus'' and ''Lolium arundinaceum'') is a species of grass commonly known as tall fescue. It is a cool-season perennial C3 species of bunchgrass native to Europe. It is an important forage grass throughout Europe, and many cultivars have been used in agriculture. It is also an ornamental grass in gardens, and a phytoremediation plant. The predominant cultivar found in British pastures is S170, an endophyte-free variety. In its native European environment, tall fescue is found in damp grasslands, river banks, and in coastal seashore locations. Its distribution is a factor of climatic, edaphic, or other environmental attributes. In New Zealand, where it is introduced, the species is particularly prolific in salt marshes, where it is often a major part of the plant biota. History Festuca arundinacea was originally developed in Kew Gardens in the United Kingdom.Cougnon et al. (2013). Performance and quality of tall fescue (Fest ...

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, ...
