Acacia mariae (synonym: Acacia tindaleae)

Golden-top Wattle, Crowned Wattle

Family: Fabaceae subfamily Mimosoideae

An erect or spreading shrub to 2 metres high, with smooth bark. It is naturally found mostly in the central and western parts of New South Wales, being fairly common in the Pilliga Scrub, growing in sand. It tends to be found in Eucalyptus–Callitris dry sclerophyll forest, woodland and mallee communities. There are some North Coast collection records as well.

Phyllodes (modified leaves) are sometimes whorled or clustered to 1.3 cm long and to 2 mm wide. Flowers are produced in globular heads with up to 40 flowers per head. The heads are produced solitarily in the axils of phyllodes, to 7 mm in diameter and bright yellow in colour. Hence, each individual flower is very small.  Seed pods are straight and flat to 6 cm long and to 10.5 mm wide.

In the garden

Cultivation details are unavailable, however it appears it will grow well in a dry situation on sandy soil.

Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.


Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.

Other information

An attractive hybrid, Acacia mariae × A. semilunata, was found in a nursery and is now in cultivation as Acacia ‘Annan Gold’ at The Australian Botanic Garden, Mount Annan.

Most wattle species will regenerate from the seedbank after fire.

Acacia – from Greek acis, a thorn.
tindaleae/ (mariae) – named by Leslie Pedley (1930–2018) who was an Australian botanist who specialised in the genus Acacia, in honour of Dr Mary D Tindale (1920–2011), another Australian botanist who made significant contributions to the systematics of Australian acacias and ferns.

The former species name A. tindaleae is now under A. conferta as it was found that the type specimen is a variant of A. conferta. However, most specimens formerly identified as A. tindaleae are now re-named as A. mariae.

To keep this honour, the renamed species epithet, A. mariae, still refers to “Mary” Tindale (named by Phillip Kodela and Gwen Harden).

Not known to be at risk in the wild.
