description

Vegetative characteristics

The Chinese beech grows as a deciduous tree that can reach heights of up to 25 meters. The winter buds are up to 2 centimeters in size.

The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The petiole is 1 to 3.5 inches long. The simple leaf blade is egg-shaped to oblong-egg-shaped with a length of 9 to 15 centimeters with a broadly wedge-shaped to approximately rounded blade base and pointed or pointed tip of the blade . The edges of the spread are bulged and sawn. The slightly glauke underside of the leaves is dense and finely hairy, while the upper side is glabrous. From the main nerve, 9 to 15 lateral nerves originate on each side, each ending in a small tooth on the leaf margin.

Generative characteristics

The Chinese beech is single-sexed ( monoecious ). The flower stalk is 1 to 10 inches long. The flowering period in China extends from April to May.

The fluffy, hairy fruit cups (cupula) are 2 to 2.5 centimeters long and contain a nut that is the same size or slightly smaller than the fruit cup. The beechnuts have small wings at the tip and ripen in China from August to October.
