Many elm (''Ulmus'') trees of various kinds have attained great size or otherwise become particularly noteworthy; among these are the following. ==American Elm ''Ulmus americana''== Most of North America's notable elms are ''Ulmus americana'', a fast-growing and long-lived species capable of attaining great size in a few centuries, especially when open-grown. * The Treaty Elm, Philadelphia, Pennsylvania. In what is now Penn Treaty Park, the founder of Pennsylvania, William Penn, is said to have entered into a treaty of peace in 1683 with the native Lenape Turtle Clan under a picturesque elm tree immortalized in a painting by Benjamin West. West made the tree, already a local landmark, famous by incorporating it into his painting after hearing legends (of unknown veracity) about the tree being the location of the treaty. No documentary evidence exists of any treaty Penn signed beneath a particular tree. On 6 March 1810 a great storm blew the tree down. Measurements taken at the time showed it to have a circumference of , and its age was estimated to be 280 years. Wood from the tree was made into furniture, canes, walking sticks and various trinkets that Philadelphians kept as relics. * The Washington Elm, Cambridge, Massachusetts. George Washington is said to have taken command of the American Continental Army under the Washington Elm in Cambridge on 3 July 1775. The tree survived until the 1920s and "was thought to be a survivor of the primeval forest". In 1872, a large branch fell from it and was used to construct a pulpit for a nearby church.〔Platt, Rutherford, "(1001 Questions Answered About Trees )", 1992, Courier Dover Publications, ISBN 0-486-27038-6, accessed 20 October 2007〕 The tree, an American White Elm, became a celebrated attraction, with its own plaque, a fence constructed around it and a road moved in order to help preserve it.〔, text was part of a brochure, "originally published in 1993 as a 14-page brochure produced by the Washington State House of Representatives", according to the Web page, accessed 20 October 2007〕 The tree was cut down (or fell – sources differ) in October 1920 after an expert determined it was dead. The city of Cambridge had plans for it to be "carefully cut up and a piece sent to each state of the country and to the District of Columbia and Alaska," according to ''The Harvard Crimson''. As late as the early 1930s, garden shops advertised that they had cuttings of the tree for sale, although the accuracy of the claims has been doubted. A Harvard "professor of plant anatomy" examined the tree rings days after the tree was felled and pronounced it between 204 and 210 years old, making it at most 62 years old when Washington took command of the troops at Cambridge. The tree would have been a little more than two feet in diameter (at 30 inches above ground) in 1773.〔Jack, J. G., "(The Cambridge Washington Elm )", article in the "Bulletin of Popular Information" of Harvard University's Arnold Arboretum, 10 December 1931, accessed 20 October 2007〕 In 1896, an alumnus of the University of Washington, obtained a rooted cutting of the Cambridge tree and sent it to Professor Edmund Meany at the university. The cutting was planted, cuttings were then taken from it, including one planted on 18 February 1932, the 200th anniversary of the birth of George Washington, for whom Washington state is named. That tree remains on the campus of the Washington State Capitol. Just to the west of the tree is a small elm from a cutting made in 1979.〔 * The Liberty Tree, an elm on Boston Common in Boston, Massachusetts, was a rallying point for the growing resistance to the rule of England over the American colonies. * George Washington's Elm, Washington, D.C. George Washington supposedly had a favorite spot under an elm tree near the United States Capitol Building from which he would watch construction of the building. The elm stood near the Senate wing of the Capitol building until 1948.〔 * The Logan Elm stood near Circleville, Ohio. The tree had a trunk circumference of and a crown spread of .〔(【引用サイトリンク】url=http://www.over-land.com/st_loganelm.html )〕 Weakened by Dutch Elm Disease, the tree died in 1964 from storm damage.〔 The Logan Elm State Memorial commemorates the site and preserves various associated markers and monuments.〔 According to tradition, Chief Logan of the Mingo tribe delivered a passionate speech at a peace-treaty meeting under this elm in 1774,〔 said to be the most famous speech ever given by a Native American. * "Herbie" in Yarmouth, Maine, stood by present-day East Main Street (Route 88) from 1793-2010.〔("Will elm trees make their way back?" ) St. ''Joseph's College Magazine''〕 At in height, it was believed to be, between 1997 and the date of its felling,〔According to the plaque on its trunk.〕 the oldest〔''Images of America: Yarmouth'', Hall, Alan M., Arcadia (2002)〕 and tallest ''Ulmus americana'' in New England.〔(The National Register of Big Trees: 2000-01 )〕 The tree, which partially stood in the front yard of a private residence, also had a circumference and (until mid-2008) a crown spread.〔 As of 2003, only twenty of Yarmouth's original 739 elms had survived Dutch elm disease.〔("Champion of Trees" - American Profile )〕 In August 2009 it was revealed that, after battling fifteen bouts of Dutch elm disease, the tree had lost, and on 19 January 2010 it was cut down.〔("Farewell to Herbie and a 'beautiful' relationship'" ). ''Portland Press Herald'', 19 January 2010〕 * The Johnstown Elm, in Johnstown, NY, as of September, 2013, does not show any signs of Dutch elm disease. It has a circumference of 196 inches (~ 16 feet), a height of 85 feet, and a crown of 88 feet. It is growing in the front yard of a house in a small upstate city, and is probably over 200 years old. See photo at right. * The Sauble Elm. With a girth of 24 feet 9 inches and a height of over 40 meters, the Sauble Elm, a white elm (''Ulmus americana'') which once grew beside the banks of the Sauble River between the towns of Hepworth and Sauble Beach in the county of Bruce in the province of Ontario, was one of the largest "wild" elms in North America. The tree succumbed to Dutch Elm Disease and was felled in 1968. A ring count established that it had begun life in the year 1701.〔(【引用サイトリンク】title=Lord Of The Elms )〕 * The Philipsburg Elm, Philipsburg, Quebec, was a 280-year-old 30-meter ''Ulmus americana'', dubbed "the king of elms". It was cut down in March 2009 after death from Dutch Elm Disease.〔(Radio-Canada, accessed 10 March 2009 )〕 * The Great Elm on Boston Common, supposed to have been in existence before the settlement of Boston, at the time of its destruction by the storm of 15 February 1876 measured in circumference.〔(【引用サイトリンク】title=Boston Common Great Elm )〕 * "Elmo", Brown University, Providence, Rhode Island, a large elm that "once defined the Thayer Street entrance to Brown’s new Watson Institute for International Studies," contracted Dutch Elm disease and was torn down in December 2003, according to a campus news release. The tree "was thought to have been between 80 and 100 years old. Wood from the tree, one of the largest on campus, was used in various student art projects."〔("The Elm Tree Project: Brown’s once-mighty 'Elmo' is preserved through artists’ project" ), 14 May 2004, "Contact Mary Jo Curtis", accessed 20 October 2007〕 * The Tabletop Elm in Provo, Utah. Next to the USU Utah County Extension Office resides possibly a one-of-a-kind elm tree. Officially it is a specimen of ''Ulmus americana'', but is unusual because it grows sideways, making it a "tabletop" elm tree. The tree was planted in 1927, and currently its several branches are supported by specialized braces to allow movement and growth. Every fall seven dump truck loads are required to remove all the leaves. * The Association Island Elm, New York State. The General Electric think tank organization, the Elfun Society, founded in 1928 at Association Island in the Thousand Islands area of northern New York state, is named after a famous elm tree on the isle. The tree died in the 1970s, but it survives in the elm tree logo still used by Elfun. * New Haven, Connecticut, had the first public tree planting program in America, producing a canopy of mature trees (including some large elms) that gave New Haven the nickname "The Elm City".〔(They’re Putting The "Elm" Back In "Elm City" )〕 This later gave rise to the Yale song, ''Neath the Elms''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of elm trees」の詳細全文を読む スポンサード リンク
