Hornbeam
Hardwood trees known for dense timber and distinctive fluted trunks.
Hornbeams are hardwood trees in the plant genus Carpinus within the family Betulaceae. They occur across much of the temperate regions of the Northern Hemisphere, with 45 accepted species, the greatest number found in east Asia, particularly China. The common English name derives from the hardness of the wood (likened to horn) and the Old English beam for 'tree.'

Lore & Background
Hornbeams are small, slow-growing, understory trees with a natural, rounded form, typically growing 4.5–9 meters (15–30 feet) tall and wide, though the European hornbeam can reach 32 meters (105 feet). Their leaves are deciduous, dark-green, alternate, and simple with coarsely-serrated margins, turning shades of yellow, orange, and red in autumn. Saplings, stressed trees, and lower branches of mature trees may exhibit marcescence, where leaves wither in autumn but remain until spring. The smooth, gray trunk and larger branches display a distinctive muscle-like fluting.
