description
Vegetative characteristics
The Taiwanese beech grows as a deciduous tree that can reach heights of up to 20 meters. The winter buds grow to around 1.5 centimeters.
The leaves are arranged alternately on the branches. The simple leaf blade is 3 to 7 centimeters in length diamond to ovoid with a broad wedge-shaped to approximately rounded blade base and a pointed or finely prickly tip. The edges of the spread are bulged and serrated. Both the underside and the upper side of the leaf are hairy silky in young leaves, while older leaves, with the exception of the leaf glands and some parts of the leaf veins, are bare. Five to nine lateral nerves originate from the main nerve on each side, each ending in a small tooth on the leaf margin.
Generative characteristics
The Taiwanese beech is single-sexed ( monoecious ) and is pollinated by the wind ( anemophilia ). The flowers are on a finely hairy, 0.5 to 2 centimeter long peduncle. The flowering period extends from April to May.
The finely hairy fruit cups (cupula) are 0.7 to 1 centimeter long and contain a nut which is the same size as the fruit cup. The beechnuts have very small wings at the tip and ripen in August through October.
