Nothofagus menziesii, commonly known as silver beech (Māori: tawhai, tahina), is a tree of the southern beech family endemic to New Zealand. Its common name probably comes from the fact that its bark is whitish in colour, particularly in younger specimens.[1] It is found from Thames southwards in the North Island (except Mount Taranaki/Egmont),[2] and throughout the South Island. Silver beech is a forest tree up to 30 m tall. The trunk, which is often buttressed, may be up to 2 m in diameter.[1][3] The leaves are small, thick and almost round in shape, 6 to 15 mm long and 5 to 15 mm wide with rounded teeth which usually occur in pairs,[1] 1 or 2 hair fringed domatia are found on the underside of each leaf.[1][2] Its Māori name is Tāwhai. It grows from low altitudes to the mountains. N. menziesii was proposed to be renamed Lophozonia menziesii in 2013.[4]
Cultivation and uses
The wood is hard and is used for furniture. It is not durable outdoors. The bark contains a black dye and tannin which is used for tanning leather.
