Pennantia

Pennantia is the sole genus in the plant family Pennantiaceae. In older classifications, it was placed in the family Icacinaceae. Most authorities have recognised three or four species, depending on whether they recognised "Pennantia baylisiana" as a separate species from "Pennantia endlicheri". Mabberley, however, has recognised only two species. "Pennantia" species grow naturally in New Zealand, Norfolk Island, and eastern Australia. In Australia, "P. cunninghamii" grows across a broad latitudinal natural range (nearly ), from the south coast of New South Wales northwards through to north eastern Queensland.
"Pennantia" are small to medium, sometimes multi-trunked trees. Leaves are alternate, leathery, and with entire or sometimes toothed margins. Inflorescences are terminal and flowers are functionally unisexual; the species are more or less dioecious.
