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. British-born botanist David Mabberley has recognised two species.

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.

Pennantia species grow naturally in New Zealand, Norfolk Island, and eastern Australia. In Australia, P. cunninghamii grows across a broad latitudinal natural range (nearly 3000 km), from the south coast of New South Wales northwards through to north eastern Queensland.

The genus name, Pennantia, is in honor of Thomas Pennant, an 18th century Welsh zoologist and author.
