Plank Buttresses

In New Zealand pukatea (Laurelia novae-zelandiae) often has well defined plank buttresses (Fig. 9). Other trees may also have buttresses: e.g. kohekohe (Dysoxylum spectabile), kahikatea (Dacrycarpus dacrydioides), and some species of beech (Nothofagus), but these are usually not plank-like.
