Hornbeams are hardwood trees. They are in the plant genus Carpinus in the family Betulaceae. They occur in the temperate zone of the Northern Hemisphere.
The American hornbeam is sometimes known as blue-beech, ironwood, or musclewood.
The botanical name for the genus, Carpinus, is the original Latin name for the European species. The fossil record of the genus goes back to the early Eocene of northwestern North America. The species Carpinus perryae is known from fossil fruits found in the Klondike Mountain Formation of Republic, Washington.[1]
