Populus × Euramericana
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar (Populus trichocarpa, ''P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The Bark (botany), bark on young trees is smooth and white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole (botany), petiole; in species in the sections ''Populus'' ...

Liriodendron Tulipifera
''Liriodendron tulipifera''—known as the tulip tree, American tulip tree, tulipwood, tuliptree, tulip poplar, whitewood, fiddletree, lynn-tree, hickory-poplar, and yellow-poplar—is the North American representative of the two-species genus ''Liriodendron'' (the other member is ''Liriodendron chinense''). It is native to eastern North America from Southern Ontario and possibly southern Quebec to west to Illinois, and east to southwestern Massachusetts, then south to central Florida and Louisiana. The tulip tree is the tallest tree of the temperate deciduous forest. It can grow to more than in virgin cove forests of the Appalachian Mountains, often with no limbs until it reaches in height, making it a very valuable timber tree. This species is also fast-growing, without the common problems of weak wood strength and short lifespan often seen in fast-growing species. In 2024 the unusual combination of fast-growing with strong wood was explained. No longer called a hardwood, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
