Pouteria costata Pouteria costata is a small coastal tree native to the northern North Island (New Zealand) and to Norfolk Island (Australia). In New Zealand, its common name is Tawāpou (from Māori); on Norfolk Island it is called bastard ironwood. The name "costata" is from the Latin "costatus" (ribbed), a reference to the prominently raised primary nerves of the leaves. "Pouteria" is a genus of approximately 300 species in the tropics of America, Asia, Australia and the Pacific. A "Pouteria" species found in other Pacific Islands is sometimes erroneously included in "P. costata".
