47-521: The event was inaugurated on 9 March 1935, when Head Play defeated Top Row and Ladysman on a muddy track by 2 lengths in a time of 1:51 4 ⁄ 5 before a crowd of 45,000 on the closing day of Santa Anita meeting. In 1937 an even greater crowd came to witness Seabiscuit set a new track record for the 1 + 1 ⁄ 8 miles winning by 7 lengths. The event in 1940 only it was limited to three-year-olds and for three-year-olds and older in all other years prior to 1968. From its inception through 1953,

94-499: A sod -forming perennial grass used in agriculture is Thinopyrum intermedium . Grasses are used as raw material for a multitude of purposes, including construction and in the composition of building materials such as cob , for insulation, in the manufacture of paper and board such as oriented structural straw board . Grass fiber can be used for making paper , biofuel production, nonwoven fabrics, and as replacement for glass fibers used in reinforced plastics. Bamboo scaffolding

141-486: A $ 30,000 offer for the colt from Suzanne Mason, wife of construction contractor Silas B. Mason whose consortium built the Grand Coulee Dam . With jockey Fisher on Head Play again, he finished second by a nose to Brokers Tip ridden by Don Meade after a battle between the two jockeys so severe they would both be suspended by the racing authorities. Convinced that Head Play would have won had it not been for

188-623: A Grade I event, the about 1 + 3 ⁄ 4 miles San Juan Capistrano Invitational Handicap now holds a Grade III classification. Since 2007, the winner of the San Juan Capistrano has received ballot-free entry into Australia's greatest horse race and the staying championship of the world, the Melbourne Cup . Since 2008, no San Juan Capistrano winner has made the trip to Flemington for the Melbourne Cup. The event

235-584: A photosynthetic pathway, linked to specialized Kranz leaf anatomy , which allows for increased water use efficiency , rendering them better adapted to hot, arid environments. The C3 grasses are referred to as "cool-season" grasses, while the C4 plants are considered "warm-season" grasses. Although the C4 species are all in the PACMAD clade (see diagram below), it seems that various forms of C4 have arisen some twenty or more times, in various subfamilies or genera. In

282-513: A right turn is used (the other is at Kentucky Downs ). After a brief straight run, there is a gentle turn to the left until the horses cross the dirt course and enter the main turf oval. Horses then run one full lap of the turf course to complete the 1 mile 1,232 yards (2.736 km) distance. In 2016 the Santa Anita's downhill chute was under repair, and the race was run on the flat turf oval, at 1 + 7 ⁄ 8 miles. In 1964,

329-596: A smaller part of the vegetation in almost every other terrestrial habitat. Grass-dominated biomes are called grasslands. If only large, contiguous areas of grasslands are counted, these biomes cover 31% of the planet's land. Grasslands include pampas , steppes , and prairies . Grasses provide food to many grazing mammals, as well as to many species of butterflies and moths . Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle , sheep , horses , rabbits and many invertebrates , such as grasshoppers and

376-910: A variety that include grasses that are related to modern rice and bamboo . Grasses have adapted to conditions in lush rain forests , dry deserts , cold mountains and even intertidal habitats , and are currently the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife. A cladogram shows subfamilies and approximate species numbers in brackets: Chloridoideae (1600) Danthonioideae (300) Micrairoideae (200) Arundinoideae (50) Panicoideae (3250) Aristidoideae (350) Oryzoideae (110) Bambusoideae – bamboos (1450) Pooideae (3850) Puelioideae (11) Pharoideae (13) Anomochlooideae (4) Before 2005, fossil findings indicated that grasses evolved around 55 million years ago. Finds of grass-like phytoliths in Cretaceous dinosaur coprolites from

423-473: Is a grass used as a culinary herb for its citrus-like flavor and scent. Many species of grass are grown as pasture for foraging or as fodder for prescribed livestock feeds, particularly in the case of cattle , horses , and sheep . Such grasses may be cut and stored for later feeding, especially for the winter, in the form of bales of hay or straw , or in silos as silage . Straw (and sometimes hay) may also be used as bedding for animals. An example of

470-470: Is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses . It includes the cereal grasses, bamboos , 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

517-570: Is able to withstand typhoon-force winds that would break steel scaffolding. Larger bamboos and Arundo donax have stout culms that can be used in a manner similar to timber, Arundo is used to make reeds for woodwind instruments , and bamboo is used for innumerable implements. Phragmites australis (common reed) is important for thatching and wall construction of homes in Africa. Grasses are used in water treatment systems, in wetland conservation and land reclamation , and used to lessen

611-606: Is linked to crop improvement, since meiotic recombination is an important component of plant breeding . Unlike in animals, the specification of both male and female plant germlines occurs late in development during flowering. The transition from the sporophyte phase to the gametophyte state is initiated by meiotic entry. Grasses are, in human terms, perhaps the most economically important plant family. Their economic importance stems from several areas, including food production, industry, and lawns . They have been grown as food for domesticated animals for up to 6,000 years and

658-454: The Aristida genus for example, one species ( A. longifolia ) is C3 but the approximately 300 other species are C4. As another example, the whole tribe of Andropogoneae , which includes maize , sorghum , sugar cane , " Job's tears ", and bluestem grasses , is C4. Around 46 percent of grass species are C4 plants. The name Poaceae was given by John Hendley Barnhart in 1895, based on

705-720: The Albian stage of the Early Cretaceous approximately 113–100 million years ago, which were found to belong to primitive lineages within Poaceae, similar in position to the Anomochlooideae. These are currently the oldest known grass fossils. The relationships among the three subfamilies Bambusoideae, Oryzoideae and Pooideae in the BOP clade have been resolved: Bambusoideae and Pooideae are more closely related to each other than to Oryzoideae. This separation occurred within

752-508: The Americas ). Sugarcane is the major source of sugar production. Additional food uses of sugarcane include sprouted grain , shoots , and rhizomes , and in drink they include sugarcane juice and plant milk , as well as rum , beer , whisky , and vodka . Bamboo shoots are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh, fermented and canned versions. Lemongrass

799-556: 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 , oats , barley , and millet for people and 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

846-458: The Cenozoic contributed to the spread of grasses. Without large grazers, fire-cleared areas are quickly colonized by grasses, and with enough rain, tree seedlings. Trees eventually outcompete most grasses. Trampling grazers kill seedling trees but not grasses. Sexual reproduction and meiosis have been studied in rice , maize , wheat and barley . Meiosis research in these crop species

893-422: The ligule lies at the junction between sheath and blade, preventing water or insects from penetrating into the sheath. Flowers of Poaceae are characteristically arranged in spikelets , each having 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. A spikelet consists of two (or sometimes fewer) bracts at

940-562: The Poaceae are used as building materials ( bamboo , thatch , and straw ); others can provide a source of biofuel , primarily via the conversion of maize to ethanol . Grasses have stems that are hollow except at the nodes and narrow alternate leaves borne in two ranks. The lower part of each leaf encloses the stem, forming a leaf-sheath. The leaf grows from the base of the blade, an adaptation allowing it to cope with frequent grazing. Grasslands such as savannah and prairie where grasses are dominant are estimated to constitute 40.5% of

987-742: The San Juan Capistrano Handicap was run in two divisions. In 1965 it became an invitational event and was named the San Juan Capistrano Invitational Handicap. With the increasing emphasis on speed horses bred to compete in the Kentucky Derby and Breeders' Cup Classic distance of 1 + 1 ⁄ 4 miles on dirt, during the last two decades longer races run on grass or dirt in North America have been in decline. Once

1034-442: 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 flowers are usually hermaphroditic — maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. The perianth is reduced to two scales, called lodicules , that expand and contract to spread

1081-450: The caterpillars of many brown butterflies . Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. Grasses dominate certain biomes , especially temperate grasslands , because many species are adapted to grazing and fire. Grasses are unusual in that the meristem is near the bottom of the plant; hence, grasses can quickly recover from cropping at the top. The evolution of large grazing animals in

1128-835: The erosional impact of urban storm water runoff. Pollen morphology, particularly in the Poaceae family, is key to figuring out their evolutionary relationships and how environments have changed over time . Grass pollen grains, however, often look the same, making it hard to use them for detailed climate or environmental reconstructions. Grass pollen has a single pore and can vary a lot in size, from about 20 to over 100 micrometers, and this size difference has been looked into for clues about past habitats, to tell apart domesticated grasses from wild ones, and to indicate various biological features like how they perform photosynthesis , their breeding systems, and genetic complexity. Yet, there's ongoing debate about how effective pollen size

1175-469: The full list of Poaceae genera . The grass family is one of the most widely distributed and abundant groups of plants on Earth . Grasses are found on every continent, including Antarctica . The Antarctic hair grass, Deschampsia antarctica is one of only two plant species native to the western Antarctic Peninsula . Grasses are the dominant vegetation in many habitats, including grassland , salt-marsh , reedswamp and steppes . They also occur as

1222-478: The grains of grasses such as wheat , rice, maize (corn) and barley have been the most important human food crops . Grasses are also used in the manufacture of thatch , paper , fuel , clothing , insulation , timber for fencing , furniture , scaffolding and construction materials, floor matting , sports turf and baskets . Of all crops grown, 70% are grasses. Agricultural grasses grown for their edible seeds are called cereals or grains (although

1269-403: The jockeys antics, his new connections entered Head Play in the $ 25,000 Preakness Stakes run at a mile and three sixteenth at Baltimore's Pimlico Race Course . In the time leading up to the race, he began uneasy in the paddock, bucking and exhibiting fractious behavior and was unable to be placed in the stall for saddling. In the race, he broke from gate four as the post time 2-1 favorite. He

1316-463: The land area of the Earth , excluding Greenland and Antarctica . Grasses are also an important part of the vegetation in many other habitats, including wetlands , forests and tundra . Though they are commonly called "grasses", groups such as the seagrasses , rushes and sedges fall outside this family. The rushes and sedges are related to the Poaceae, being members of the order Poales , but

1363-647: The last quarter mile to win by four lengths. He won the Preakness in a final time of 2:02, paying $ 5.60 to win. The Derby winner, Brokers Tip, finished last in the field of ten. Tom Hayes had taken over as the trainer for the new owner after the Derby and the Preakness win with Head Play marked his second win in the event, having won in 1897 with the colt Paul Kauvar . Only a few months after, Hayes died on August 28, 1933, at his home in Lexington, Kentucky. Head Play

1410-453: The latest Cretaceous ( Maastrichtian ) aged Lameta Formation of India have pushed this date back to 66 million years ago. In 2011, fossils from the same deposit were found to belong to the modern rice tribe Oryzeae , suggesting substantial diversification of major lineages by this time. In 2018, a study described grass microfossils extracted from the teeth of the hadrosauroid dinosaur Equijubus normani from northern China, dating to

1457-624: The latter term, when used agriculturally, refers to both cereals and similar seeds of other plant species, such as buckwheat and legumes ). Three cereals—rice, wheat, and maize (corn)—provide more than half of all calories consumed by humans. Cereals constitute the major source of carbohydrates for humans and perhaps the major source of protein; these include rice (in southern and eastern Asia ), maize (in Central and South America ), and wheat and barley (in Europe , northern Asia and

1504-463: The leaves are attached. Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem and a blade with entire (i.e., smooth) margins. The leaf blades of many grasses are hardened with silica phytoliths , which discourage grazing animals; some, such as sword grass , are sharp enough to cut human skin. A membranous appendage or fringe of hairs called

1551-469: The lemma and palea; these are generally interpreted to be modified sepals. The fruit of grasses is a caryopsis , in which the seed coat is fused to the fruit wall. A tiller is a leafy shoot other than the first shoot produced from the seed. 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

1598-542: The oldest horses to win the event. Two mares have won the event, La Zanzara (1975) and the Champion Argentine mare Miss Grillo (1949). The event had showcased many a champion and notable runnings. In 1950 the Irish-bred champion Noor defeated the 1948 Triple Crown champion Citation by a neck before a crowd of about 60,000. The March 12, 1966, edition of the San Juan Capistrano Invitational Handicap

1645-705: The one and one sixteenth mile Hawthorne Juvenile Stakes in December at Hawthorne Race Course in Cicero, Illinois , before being freshened over the winter. In his three-year-old season, with jockey Herb Fisher aboard he won the Derby Trial Stakes at one mile at Churchill Downs on opening weekend. After that impressive win, in which he beat a number of the Kentucky Derby eligibles, the Crumps accepted

1692-400: The plant. 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. There are both C3 and C4 grasses, referring to the photosynthetic pathway for carbon fixation. The C4 grasses have

1739-877: The prestigious Suburban Handicap at 1 + 1 ⁄ 4 miles on the dirt at Belmont Park in New York over Discovery with Cavalcade losing his rider at the start. He won the Derby Week Special at one and one eighth miles at Detroit in mid-June over Stand Pat and Azucar. He bowed slightly after this and never regained his form, racing only twice the next year unsuccessfully. bay 1919 ch. 1905 bay 1910 ch. 1923 ch. 1913 ch. 1918 Legend – ₩ = Triple Crown Winners, ♥ = Filly Grass Gramineae  Juss.

1786-502: The race was contested on dirt, then in 1954 it was converted to a turf event. The San Juan Capistrano is run around four turns, and begins at the top of Santa Anita's downhill chute, normally used for 6 + 1 ⁄ 2 -furlong sprint races. From the start point, horses begin their descent down the hill. Within the first two furlongs of the race, horses turn right – one of only two locations in North American horse racing that

1833-629: The relatively short time span of about 4 million years. According to Lester Charles King , the spread of grasses in the Late Cenozoic would have changed patterns of hillslope evolution favouring slopes that are convex upslope and concave downslope and lacking a free face were common. King argued that this was the result of more slowly acting surface wash caused by carpets of grass which in turn would have resulted in relatively more soil creep . There are about 12,000 grass species in about 771 genera that are classified into 12 subfamilies. See

1880-412: The seagrasses are members of the order Alismatales . However, all of them belong to the monocot group of plants. Grasses may be annual or perennial herbs , generally with the following characteristics (the image gallery can be used for reference): The stems of grasses, called culms , are usually cylindrical (more rarely flattened, but not 3-angled) and are hollow, plugged at the nodes , where

1927-698: The second half of April at the same distance at Santa Anita Park outside Los Angeles in California. Then he won the Bay Meadows Handicap at one and one eighth miles in the San Francisco Area in Northern California at Bay Meadows Racetrack . In May, he ran against the 1934 Kentucky Derby winner, Cavalcade , at Belmont and recorded an upset victory over the younger horse. On the fourth of July weekend, Head Play won

1974-466: The tribe Poeae described in 1814 by Robert Brown , and the type genus Poa described in 1753 by Carl Linnaeus . The term is derived from the Ancient Greek πόα (póa, "fodder") . Grasses include some of the most versatile plant life-forms . They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung ( coprolites ) have been found containing phytoliths of

2021-465: Was an American Thoroughbred racehorse best known for winning the 1933 Preakness Stakes , the second leg of the U.S. Triple Crown series of races and as the horse on the losing end of the "Fighting Finish" of the 1933 Kentucky Derby. Trainer Willie Crump, a former top jockey, bought Head Play for $ 500 at a yearling sale and gave him to his wife Ruth to race under her name. At age two, Head Play broke his maiden in his second start. He went on to win

2068-503: Was downgraded to a Grade II in 2004 and to a Grade III race in 2015. The event for many runnings was held on the closing day of the Santa Anita spring meeting, which was in April. However, with the takeover of events from the close of Hollywood Park Racetrack in 2013, the event has been held in June, with three-year-olds allowed to enter. At age eight, Niarkos (1968) and Mashkour (1991) are

2115-430: Was immediately sent by his jockey Charles Kurtsinger to the outside, shifting across several other paths to the middle of the track. He outran all others, including Kentucky Derby winner Brokers Tip , to the first turn, completing the first quarter mile in :23-3/5. He rated by slowing down the pace on the back stretch but was still in front comfortably. He shook off several challenges from Ladysman and then drew off in

2162-568: Was injured and did not win another race in the remainder of his three-year-old or four-year-old seasons. As a five-year-old, he came back into form from his injury and won four stakes races on separate coasts of the country. Early in 1935, he won both the inaugural running of the San Antonio Handicap in the first week of February at one and one eighth mile on the dirt and the San Juan Capistrano Handicap in

2209-406: Was seen by 60,792 fans, the largest crowd of the season, who turned out to say farewell to retiring U.S. Racing Hall of Fame jockey Johnny Longden . Without ever using the whip as he always did, Longden guided Canadian bred George Royal from fifteen lengths back in last place to a photo-finish win.
