What is "cunonia"

Cunonia is a genus of shrubs and trees in the family Cunoniaceae. The genus has a disjunct distribution, with 24 species endemic to New Caledonia in the Pacific, and one species ( Cunonia capensis) in Southern Africa. Leaves are opposite, simple or pinnate with a margin entire to serrate. Interpetiolar stipules are often conspicuous and generally enclose buds to form a spoon-like shape (hence the common name "Butterspoon Tree" for Cunonia capensis). Flowers are bisexual, white, red (pink to purple), or green, arranged in racemes. The fruit is a capsule opening first around the base then vertically, seeds are winged.
