Eucalyptus brandiana

Common Name: Square Fruited Mallet

Family: MYRTACEAE (c. 150 genera)

Origin of Scientific Name:

Eucalyptus - Greek eu = well + calyptos = covered, referring to the operculum or cap covering the stamens in the bud.

brandiana – named after Grady Brand, Senior Curator of Kings Park and Botanic Garden.

Description

Eucalyptus brandiana is a single-stemmed tree to 5 metres with a conspicuous crown and lacking a lignotuber (a starchy swelling of the root crown which allows for regeneration after extensive damage, including destruction by fire), hence the classification of ‘mallet’. This eucalypt has extraordinarily large, thick, glossy green leaves not unlike ficus leaves, and very large fruits and flowers up to 5 cm across. These start off as pendulous red buds, but the anthers themselves are pink.
