For example, balsa wood, which is a hardwood, is softer than most softwoods, whereas the longleaf pine, Douglas fir, and yew softwoods are much harder than several hardwoods. [citation needed] Several specific natural, macroscopic and microscopic features of wood are used in the identification process of a softwood species. [5]

Beech is a popular hardwood. Hardwood is wood from angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. [1] In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from ...
