Macadamia integrifolia Tree in Penang
Macadamia tree (Macadamia integrifolia, Macadamia tetraphylla). Common names: Queensland nut, bush nut, Maroochy nut, queen of nuts, bauple nut, gyndl, jindilli, boombera. Origin Native to eastern Australia, New Caledonia and Sulawesi in Indonesia. Belongs to Proteaceae family. Description A subtropical tree that produces a fine, creamy-sweet, round nut. Growth Habitat A mild, frost-free climate with abundant rainfall throughout the year. High summer temperatures can reduce yields. Fruits Macadamia tetraphylla trees, having rough-shelled nuts, produce nuts with high carbohydrate content, sweeter flavor, and lower oil content than those from the smooth-shelled M. integrifolia nuts. The high oil content of M. integrifolia makes it superior to M.tetraphylla for roasting and salting.
