Cordyline australis 學問
A monocotyledon endemic to New Zealand, and which is not a true palm tree. It grows up to 15 m tall, at first on a single stem, but dividing into a much-branched crown, each branch may fork after producing a flowering stem. The leaves are sword-shaped, 40 to 90 cm long and 3 to 7 cm broad at the base. The flowers are fragrant and creamy white, each flower small with six tepals, and produced in a large, dense cluster 50 to 100 cm long. The fruit is a white berry 5 to 7 mm in diameter.
