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] British-born botanist David Mabberley has recognised two species.[4]

The species 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 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.[citation needed]
The genus name, Pennantia, is in honor of Thomas Pennant, an 18th century Welsh zoologist and author.[citation needed]
Species
editThe following four species were recognised by New Zealand botanists Rhys O. Gardner and Peter J. de Lange in 2002.[3]

- Pennantia corymbosa J.R.Forst. & G.Forst., 'kaikōmako' – New Zealand
- Pennantia cunninghamii Miers, 'brown beech' – NSW, Qld, Australia
- Pennantia endlicheri Reissek – Norfolk Island
