Pennantia is the sole genus in the plant family Pennantiaceae. In older classifications, it was placed in the family Icacinaceae.[2] Most authorities have recognised three or four species, depending on whether they recognised Pennantia baylisiana as a separate species from Pennantia endlicheri.[3] Mabberley, however, has recognised only two species.[4] Pennantia species grow naturally in New Zealand, Norfolk Island, and eastern Australia. In Australia, P. cunninghamii grows across a broad latitudinal natural range (nearly 3,000 km (1,900 mi)), 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.[3]

Pennantia is named after Thomas Pennant, an 18th century Welsh zoologist and author.
