The term hardwood includes numerous species of trees and shrubs with dense, heavy wood. Depending on their density, hardwoods can be subdivided into “medium heavy,” “heavy,” “very heavy,” and woods that actually sink in water called “ironwoods.” Hardwoods are usually limited to flowering trees and shrubs because their wood contains water-conducting cells (tracheids and vessel elements) plus tightly-packed, thick-walled fiber cells which are lacking in the wood of conifers. Generally the cone-bearing trees, such as pines (Pinus), spruce (Picea), fir (Abies), and redwood (Sequoia), are considered to be softwoods because their wood is composed essentially of water-conducting cells (tracheids) without wood fiber cells.
