Lophozonia menziesii

Lophozonia menziesii or Silver beech (Māori: tawhai) 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. It is found from Thames southwards in the North Island (except Mount Taranaki/Egmont), 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. 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 or 2 hair fringed domatia are found on the underside of each leaf. Its Māori name is Tāwhai. It grows from low altitudes to the mountains. L. menziesii was known as Nothofagus menziesii prior to 2013.
