Along our coast this species is rare due to a lack of suitable site conditions. It is an open-growing, elegant shrub up to 2m in height and is confined to our moist, sheltered gullies where it gets increased soil moisture and full protection from the sun. It can be seen in places like Deep Creek in Torquay and the gullies around Bells Beach and coastal forest areas further southwest.
Leaves are orbicular to elliptic but generally rounded; arranged alternately and horizontally on branchlets.
Male and female flowers are typically on separate plants (monoecious); with many small flowers hanging in neat rows beneath leafy branchlets.
Flowers are white, yellow or greenish.

The species name refers to the 19th century botanical collector Ronald Gunn.
