Origin of Scientific Name:

Eucalyptus – (Greek) eu – well + calyptos – covered, referring to the bud cap which is released as the flowers open.

brandiana – named after Grady Brand, Senior Curator of Kings Park and Botanic Garden in recognition of his contribution to the horticulture and display of WA flora.


Eucalyptus brandiana is a distinctive single-stemmed tree to 5 metres with a conspicuous crown and attractive smooth shiny bark that is silver grey with bronze stripes. 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 four-winged buds, but the flowers themselves are bright pink and appear sporadically throughout the year, peaking in spring. In cultivation flowering can occur as late as January and February.

All known populations of this tree are located within Fitzgerald River National Park on the south coast of Western Australia; as such, it is listed as a Priority species by the Department of Biodiversity, Conservation and Attractions.

The Square Fruited Mallet was described and published as a species in its own right in 2009 by ecologist Nathan McQuoid and Professor Stephen Hopper (former BGPA Chief Executive Officer). It was named after Grady Brand, Senior Curator of Kings Park and Botanic Garden in Perth.
