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 /ˈpɒp.lər/, aspen, and cottonwood.

The western balsam poplar (P. trichocarpa) was the first tree whose full DNA code had been determined by DNA sequencing, in 2006.[1]
