Corynocarpus laevigatus

English name: Karaka

Latin name: Corynocarpus laevigatus

Family: Corynocarpaceae - Corynocarpaceae

Origin: New Zealand

The karaka is an evergreen with raised or spreading branches. It grows to a height of 15 m., and its trunk may have a diameter of up to a meter. Its thick, leathery, glossy leaves, dark green on top and paler on the underside, have a length of 5 to 20 cm. and a width of 3 to 7 cm. The petioles are 1 to 1.5 cm. long. From August to November, the karaka produces stout, raised panicles of tiny flowers. Single flowers, 4 – 5 mm. in diameter; their colours range from a greenish cream to white or pale yellow. The oval fruit, with pale yellow or orange flesh, may be up to 25 to 46 mm. long and contains a single seed. Birds who eat the fruit disperse the seeds.

The flesh is edible if bitter, though fresh kernels contain a toxic alkaloid. Poisoning can cause violent convulsions and severe muscle spasms that may lead to permanent limb deformation. Several deaths have been recorded.
