Populus
''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, 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'' and ''A ...

Populus Alba
''Populus alba'', commonly called silver poplar,Webb, C. J.; Sykes, W. R.; Garnock-Jones, P. J. 1988: Flora of New Zealand. Vol. IV. Naturalised Pteridophytes, Gymnosperms, Dicotyledons. 4. Christchurch, New Zealand, Botany Division, D.S.I.R. silverleaf poplar, or white poplar, is a species of poplar, most closely related to the aspens (''Populus'' sect. ''Populus''). It is native to Morocco and then Portugal through central Europe (north to Germany and Poland) to central Asia. It grows in moist sites, often by watersides, in regions with hot summers and cold to mild winters.Flora Europaea''Populus alba''/ref>Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . Description It is a medium-sized deciduous tree, growing to heights of up to (rarely more), with a trunk up to in diameter and a broad, rounded crown.

Populus Grandidentata
''Populus grandidentata'', commonly called large-tooth aspen, big-tooth aspen, American aspen, Canadian poplar, or white poplar, is a deciduous tree native to eastern North America. Name The name ''Populus'' is from the Latin for poplar, and ''grandidentata'' refers to the coarse teeth on the leaves (''grandis'' meaning "large", and ''dentata'' meaning "toothed"). Description ''Populus grandidentata'' is a medium-sized deciduous tree native to North America, found mostly in the northeastern United States and southeastern Canada. Leaves are similar to ''Populus tremuloides'', but slightly larger and having larger teeth. The leaves tremble in the wind as ''P. tremuloides'' does. Bark of younger trees is olive-green, thin and smooth; after 30–40 years, the bark is gray, thick and rough with grooves. Reproduction Bigtooth aspens produce seeds from wind-pollinated flower clusters, known as catkins. The tree is dioecious, meaning that male and female flowers are on separate tr ...

Populus Tremuloides
''Populus tremuloides'' is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen. It is commonly called quaking aspen, trembling aspen, American aspen, mountain or golden aspen, trembling poplar, white poplar, and popple, as well as others. The trees have tall trunks, up to 25 meters (82 feet) tall, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in autumn. The species often propagates through its roots to form large clonal groves originating from a shared root system. These roots are not rhizomes, as new growth develops from adventitious buds on the parent root system (the ortet). ''Populus tremuloides'' is the most widely distributed tree in North America, being found from Canada to central Mexico. It is the defining species of the aspen parkland biome in the Prairie Provinces of Canada and extreme northwest Minnesota. Description Quak ...
