			'''''Tsuga canadensis''''', also known as '''Eastern''' or '''Canadian Hemlock''', and in the [[French language in Canada\|French-speaking regions]] of Canada as '''Pruche du Canada''', is a [[Pinophyta\|coniferous]] [[tree]] native to eastern [[North America]]. It ranges from northeastern [[Minnesota]] eastward through southern [[Quebec]] to [[Nova Scotia]], and south in the [[Appalachian Mountains]] to northern [[Georgia (U.S. state)\|Georgia]] and [[Alabama]]. Scattered outlier populations occur in several areas east and west of the Appalachians. It is the [[List of U.S. state trees\|state tree]] of [[Pennsylvania]].<ref name=Taylor/>

			The eastern hemlock grows well in shade and is very long lived with the oldest recorded specimen being at least 554 years old.<ref name=treering>{{Citation\| last =Gove\| first =J.H.\| author-link =\| last2 =Fairweather\| first2 =S.E.\| author2-link =\| title =U.S. Forest Service General Technical Report NC-120\| contribution =Tree-ring analysis of a 500-year old hemlock in central Pennsylvania\| publisher =\| year =1988\| pages =483–489\| volume =1\| edition =\| url =\| doi =\| id =}}</ref> The tree generally reaches heights of about 31 metres (100 feet),<ref name=Taylor/> but exceptional trees have been recorded up to 53 metres (173 feet).<ref name=usis>{{Citation\| last =Blozan\| first =Will\| author-link =\| last2 =\| first2 =\| author2-link =\| title =The Usis Hemlock Climb\| date =February 16, 2007\| url =http://www.nativetreesociety.org/fieldtrips/gsmnp/usis/usis_hemlock_climb.htm\| accessdate = 2007-06-08}}</ref> The diameter of the trunk at breast height is often 1.5 metres (5 feet), but again, outstanding trees have been recorded up to 1.75 meters (6 feet).<ref name=laurel>{{Citation\| last =Blozan\| first =Will\| author-link =\| last2 =\| first2 =\| author2-link =\| title =The Laurel Branch Leviathan Climb\| date =December 18, 2006\| url =http://www.nativetreesociety.org/tsuga/laurel_branch/laurel_branch_leviathan_climb.htm\| accessdate =2007-06-08}}</ref> The trunk is usually straight and monopodial, but very rarely is forked.<ref name=farjon/> The crown is broadly conic, while the brownish [[bark]] is scaly and deeply fissured, especially with age.<ref name=Taylor/> The twigs are a yellow-brown in colour with darker red-brown [[pulvinus\|pulvini]], and are densely pubescent. The [[bud]]s are ovoid in shape and are very small, measuring only 1.5 to 2.5 mm (0.05 to 0.1 inches) in length. These are usually not resinous, but may be slightly so.<ref name=Taylor/><ref name=farjon/>

			The leaves are typically 15 to 20 mm (0.6 to 0.9 inches) in length, but may be a short as 5 mm (0.2 inches) or as long as 25 mm (1 inch). They are flattened and are typically distichous, or two-ranked. The abaxial surface of the leaf, or underside, is glaucous with 2 broad and clearly visible [[stomata]]l bands, while the adaxial surface, i.e. the upper-side, is a shiny green to yellow-green in colour. The leaf margins are very slightly dentate, or toothed, especially near the apex. The seed [[Conifer cone\|cones]] are ovoid in shape and typically measure 1.5 to 2.5 cm (0.6 to 1 inch) in length and 1 to 1.5 cm (0.4 to 0.6 inches) in width. The scales are ovate to cuneate in shape and measure 8 to 12 mm (0.3 to 0.5 inches) in length by 7 to 10 mm (0.3 to 0.4 inches) in width. The apex is more or less rounded and is often projected outward. 24 diploid [[chromosome]]s are present within the tree's [[DNA]].<ref name=Taylor/><ref name=farjon/>
