The Poaceae (also known as the Gramineae) is a large and nearly ubiquitous family of monocot flowering plants. Members of this family are commonly called (land) grasses, although the term (land) "grass" is also applied to plants that are not in the Poaceae lineage, including the rushes (Juncaceae) and sedges (Cyperaceae). As for the seagrasses, they all belong to the Alismatales, a different monocot order altogether. This broad and general use of the word "grass" has led to plants of the Poaceae often being called "true grasses". With over 10,025 currently accepted species, the Poaceae represent the fifth largest plant family. Only the Orchidaceae, Asteraceae, Fabaceae, and Rubiaceae have more species.^[2]

Plant communities dominated by Poaceae are called grasslands; grasslands are estimated to comprise 20% of the vegetation cover of the Earth. Grass species also occur in many other habitats not formally considered to be grasslands, including different types of wetlands (e.g., fens, marshes), forests and tundra.

Poaceae are often considered to be the most important of all plant families to human economies: it includes the staple food grains and cereal crops grown around the world, lawn and forage grasses, and bamboo, which is widely used for construction throughout east Asia and sub-Saharan Africa. Civilization was founded largely on the ability to domesticate cereal grass crops around the world.

Description[link]

Structure of a grass plant

Grasses generally have the following characteristics (the image gallery can be used for reference):

Poaceae have hollow stems called culms, which are plugged (solid) at intervals called nodes, the points along the culm at which leaves arise. Grass leaves are alternate, distichous (in one plane) or rarely spiral, and parallel-veined. Each leaf is differentiated into a lower sheath, which hugs the stem for a distance and a blade with margins usually entire. The leaf blades of many grasses are hardened with silica phytoliths, which helps discourage grazing animals. In some grasses (such as sword grass), this makes the edges of the grass blades sharp enough to cut human skin. A membranous appendage or fringe of hairs, called the ligule, lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath.

Parts of a spikelet

Flowers of Poaceae are characteristically arranged in spikelets, each spikelet having one or more florets (the spikelets are further grouped into panicles or spikes). 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 called the lemma (the external one) and the palea (the internal). The flowers are usually hermaphroditic (maize, monoecious, is an exception) and pollination is always anemophilous, that is, by wind. 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. This complex structure can be seen in the image on the right, portraying a wheat (Triticum aestivum) spike.

The fruit of Poaceae is a caryopsis, in which the seed coat is fused to the fruit wall and thus, not separable from it (as in a maize kernel).

Growth and development[link]

Grass blades grow at the base of the blade and not from elongated stem tips. This low growth point evolved in response to grazing animals and allows grasses to be grazed or mown regularly without severe damage to the plant.^[3]

Three general classifications of growth habit present in grasses: bunch-type (also called caespitose), stoloniferous, and rhizomatous.

The success of the grasses lies in part in their morphology and growth processes, and in part in their physiological diversity. Most of the grasses divide into two physiological groups, using the C3 and C4 photosynthetic pathways for carbon fixation. The C4 grasses have a photosynthetic pathway linked to specialized Kranz leaf anatomy that particularly adapts them to hot climates and an atmosphere low in carbon dioxide.

C3 grasses are referred to as "cool season" grasses, while C4 plants are considered "warm season" grasses; they may be either annual or perennial.

• Annual cool season - wheat, rye, annual bluegrass (annual meadowgrass, Poa annua), and oat
• Perennial cool season - orchardgrass (cocksfoot, Dactylis glomerata), fescue (Festuca spp), Kentucky bluegrass and perennial ryegrass (Lolium perenne)
• Annual warm season - corn, sudangrass, and pearl millet
• Perennial warm season - big bluestem, indiangrass, bermudagrass and switchgrass.^[4]

Ecology[link]

Biomes dominated by grasses are called grasslands. If only large contiguous areas of grasslands are counted, these biomes cover 31% of the planet's land.^[5] Grasslands go by various names depending on location, including pampas, plains, steppes, or prairie.

In addition to their use as forage worldwide by many grazing mammals, such as cattle and other livestock, deer, and elephants, grasses are used as food plants by many species of butterflies and moths; see List of Lepidoptera that feed on grasses.

The evolution of large grazing animals in the Cenozoic has contributed to the spread of grasses. Without large grazers, a clearcut of fire-destroyed area would soon be colonized by grasses and, if there is enough rain, tree seedlings. The tree seedlings would eventually produce shade, which kills most grasses. Large animals, however, trample the seedlings, killing the trees. Grasses persist because their lack of woody stems helps them to resist the damage of trampling.^[6]

Evolution[link]

Until recently, grasses were thought to have evolved around 55 million years ago, based on fossil records. However, recent findings of 65-million-year-old phytoliths resembling grass phytoliths (including ancestors of rice and bamboo) in Cretaceous dinosaur coprolites,^[1][7] may place the diversification of grasses to an earlier date. Indeed, revised dating of the origins of the rice tribe Oryzeae have been led to the suggestion that the date might be pushed back as early as 107 Ma to 129 Ma.^[8]

The relationships among the subfamilies Bambusoideae, Ehrhartoideae and Pooideae in the BEP clade have been resolved: Bambusoideae and Pooideae are more closely related than Ehrhartoideae.^[9] This separation occurred within a relatively short time span (~4 million years).

Distribution[link]

The grass family is one of the most widely distributed and abundant groups of plants on Earth. They are found on every continent, and are essentially only absent from central Greenland and much of Antarctica.^[2]

Taxonomy[link]

Setaria verticillata from Panicoideae

Tragus roxburghii from Chloridoideae

The most recent classification of the grass family A World-wide Phylogenetic Classification of Poaceae|date=March 2012, recognizes 12 subfamilies:

• Anomochlooideae, a small lineage of broad-leaved grasses that includes two genera (Anomochloa, Streptochaeta)
• Pharoideae, a small lineage of grasses that includes three genera, including Pharus and Leptaspis
• Puelioideae, a small lineage that includes the African genus Puelia
• Pooideae, including wheat, barley, oats, brome-grass (Bromus), reed-grasses (Calamagrostis) and many lawn and pasture grasses
• Bambusoideae, including bamboo
• Ehrhartoideae, including rice, wild rice
• Aristidoideae, including [Aristida]
• Arundinoideae, including giant reed, common reed
• Chloridoideae, including the lovegrasses (Eragrostis, about 350 species, including teff), dropseeds (Sporobolus, some 160 species), finger millet (Eleusine coracana (L.) Gaertn.), and the muhly grasses (Muhlenbergia, about 175 species)
• Panicoideae, including Centothecoideae, panic grass, maize, sorghum, sugarcane, most millets, fonio, and bluestem grasses
• Micrairoideae
• Danthonioideae, including pampas grass

Depending on the classification followed, the family includes approximately 668 genera.^[2]

Etymology[link]

The Poaceae was named by John Hendley Barnhart in 1895,^[10] based on the tribe Poeae (described in 1814 by Robert Brown), and the type genus Poa (described in 1753 by Linnaeus). The term is derived from the Ancient Greek term for "grass".

Uses[link]

Grasses are, in human terms, perhaps the most economically important plant family. Grasses' economic importance stems from several areas, including food production, industry, and lawns.

Food production[link]

Agricultural grasses grown for their edible seeds are called cereals. Three cereals – rice, wheat, and maize (corn) – provide more than half of all calories eaten by humans.^[11] Of all crops, 70% are grasses.^[12] Cereals constitute the major source of carbohydrates for humans and perhaps the major source of protein, and include rice in southern and eastern Asia, maize in Central and South America, and wheat and barley in Europe, northern Asia and the Americas.

Sugarcane is the major source of sugar production. Many other grasses are grown for forage and fodder for animal feed, particularly for sheep and cattle, thereby indirectly providing more human calories.

Industry[link]

Grasses are used for construction. Scaffolding made from bamboo is able to withstand typhoon-force winds that would break steel scaffolding.^[5] Larger bamboos and Arundo donax have stout culms that can be used in a manner similar to timber, and grass roots stabilize the sod of sod houses. Arundo is used to make reeds for woodwind instruments, and bamboo is used for innumerable implements.

Grass fiber can be used for making paper, and for biofuel production.

Phragmites australis (common reed) is important in water treatment, wetland habitat preservation and land reclamation in Afro-Eurasia.

Lawn and ornamental grasses[link]

Grasses are the primary plant used in lawns, which themselves derive from grazed grasslands in Europe. They also provide an important means of erosion control (e.g., along roadsides), especially on sloping land.

Although supplanted by artificial turf in some games, grasses are still an important covering of playing surfaces in many sports, including football, tennis, golf, cricket, and softball/baseball.

Ornamental grasses, such as perennial bunch grasses, are used in many styles of garden design for their foliage, inflorescences, seed heads, and slope stabilization. They are often used in natural landscaping, xeriscaping, contemporary or modern landscaping, wildlife gardening, and native plant gardening.

Economically important grasses[link]

Grasses and society[link]

Grasses have long had significance in human society. They have been cultivated as a food source for domesticated animals for up to 10,000 years, and have been used to make paper since the second century AD.^{[citation needed]} Also, the primary ingredient of beer is usually barley or wheat, both of which have been used for this purpose for over 4,000 years.^{[citation needed]}

Some common aphorisms involve grass. For example:

• "The grass is always greener on the other side" suggests an alternate state of affairs will always seem preferable to one's own.
• "Don't let the grass grow under your feet" tells someone to get moving.
• "A snake in the grass" means dangers that are hidden.
• "When elephants fight, it is the grass which suffers" tells of bystanders caught in the crossfire.

A folk myth about grass is that it refuses to grow where any violent death has occurred.^[13]

Corb Lund and the Hurtin' Albertans are a Canadian country music band, formerly known as the Corb Lund Band.

Corb Lund[link]

Corb Lund, the lead singer, grew up in Southern Alberta living on his family's farm and ranches near Taber, Cardston and Rosemary. He is proud of being an Albertan.^[1] Lund left his hometown of Taber and moved to Edmonton, where he enrolled in the Grant MacEwan College to study jazz guitar and bass.

Lund was a founding member of The Smalls, who sold over 35,000 albums over a twelve year span, all released independently. Lund and the Smalls toured extensively in Canada, the United States and Europe, including a stint in Bosnia, Slovenia and the Czech Republic. The band retired in the fall of 2001.

The Hurtin' Albertans[link]

Hurtin' Albertans is Corb Lund's touring band. They have released five albums to critical acclaim.^[2][3] The band tours regularly in Canada, the United States and Australia. Much of their time is spent in the Canadian Prairies and the American southwest.

The band's members are:

• Kurt Ciesla, bass
• Grant "Demon" Siemens, guitar and other strings
• Brady Valgardson, drums

Siemens is the only member who is not Albertan, hailing from Winnipeg, Manitoba. Farmer/drummer Valgardson and Lund are from Taber, Alberta.

The band has toured Europe, where they played the UK Glastonbury Festival, and Australia several times. The group was featured the movie "Slither" (2006) and were part of the soundtrack to the 2008 documentary, "Holler Back: (Not) Voting in an American Town." They have also provided accompaniment for an NBC special in 2006, on which Olympic gold medalist and fellow Albertan, Kurt Browning, performed a figure skating routine to “Expectation and the Blues”. Their music can also be heard in the ski film "Nine Winters Old."

Corb Lund signed a two-album deal with New West Records (home of Dwight Yoakam, Steve Earle, Kris Kristofferson and other major artists) in 2009. His first record on New West, "Losin' Lately Gambler," was released in September 2009.

Corb Lund and the Hurtin Albertans played their 2009 single "Long Gone to Saskatchewan" in Ottawa for the 2011 Canada Day ceremonies in the presence of the newlywed Duke and Dutchess of Cambridge on their Royal visit to Canada.^[4]

John Wilson Kyle OBE (born 10 January 1926, Belfast, Northern Ireland), commonly referred to as Jack Kyle or Jackie Kyle, is a former rugby union player who played for Ireland, the British Lions and the Barbarians^[2] during the 1940s and 1950s. In 1950, Kyle was declared one of the six players of the year by the New Zealand Rugby Almanac,^[3] in 1999, he was inducted into the International Rugby Hall of Fame,^[4] in 2002, he was named the Greatest Ever Irish Rugby Player by the Irish Rugby Football Union,^{[5][dead link]} and in 2008, he was inducted into the IRB Hall of Fame.^[6]

Kyle was educated at Belfast Royal Academy and studied medicine at Queen's University, Belfast.^{[7][dead link]} He graduated in 1951 and in 1991, he was awarded an Honorary Doctorate by the University.^{[8][dead link]} In 2007, he was awarded a Lifetime Achievement Award by the Irish Journal of Medical Science and the Royal Academy of Medicine in Ireland.^[9] He has also been awarded an OBE.^{[citation needed]}

Rugby international[link]

Ireland[link]

Kyle first played for Ireland during the Second World War in a friendly against a British Army XV. However, no caps were awarded.^[10] Between 1947 and 1958, while playing for Ireland, he went onto make 46 full appearances and score 24 points, including 7 tries.^{[11][dead link]} The highlight of his Ireland career came during the 1948 Five Nations Championship when, together with Karl Mullen and Mick O'Flanagan, he helped Ireland win a grand slam.^[12] Kyle played in all four games and he is often credited with masterminding Ireland’s success.^[13] In 1949, he also helped Ireland win the Triple Crown and in 1951, they won the title again. Kyle made his last appearance for Ireland against Scotland on March 1 1958. Following a solo try against France at Ravenhill in 1953, an impressed newspaper journalist parodied The Scarlet Pimpernel with the lines:

They seek him here, they seek him there
Those Frenchies seek him everywhere.
That paragon of pace and guile,
That demned elusive Jackie Kyle.

British and Irish Lions[link]

In 1950, Kyle also played for the British Lions on their tour to New Zealand and Australia. He played in 20 of the 29 games, including all six Tests. Among his tour highlights was a display that came in the first Test, a 9-9 draw with New Zealand. Of the Lions' nine points, Kyle scored a try, created another for Ken Jones and won a penalty that was converted by John Robins. During the tour, he also scored a try in the 24-3 defeat of Australia.^[3][4]

Later years[link]

After retiring from club rugby in 1963, Kyle embarked on humanitarian work in Sumatra and Indonesia. Between 1966 and 2000, he worked as a consultant surgeon in Chingola, Zambia. He then returned to Northern Ireland and settled in County Down. He remained involved in rugby and in 2001, established the The Jack Kyle Bursary Fund in support of the Queen's University RFC Rugby Academy.^{[9] [14][15]}
