The slate to dark grey bark is thick and furrowed. The tiny red male flowers are bell-shaped and produced in large numbers while the female flowers, which are green tipped with brown, are in groups of three on short stalks growing in the axils of the leaves.[4] UsesThe bark of Nothofagus truncata has a high tannin content and has traditionally been used for tanning leather. The timber is red when freshly cut but turns pale brown as it dries. It has been used for bridge building and for making poles, fencing posts and railway sleepers.[4] The wood has a fine straight grain and even texture and is used for joinery, flooring, decking and cabinet making.[6] Hybrids
