Acacia clunies-rossiae is a bushy shrub or tree, growing in dry sclerophyll forest, in valleys, on slopes and ridges, and along creeks in the Kowmung River and adjacent Coxs River district of NSW, entirely within Kanangra-Boyd and Blue Mountains National Parks. It has a very restricted distribution.
The phyllodes (leaves) are to 7 cm long by 1 cm wide, with a small point at the tip. Young phyllodes are densely hairy.
Flowers are produced in globular flower heads with heads arranged in racemes in the leaf axils. Each spray/raceme has 8 to 25 heads. Each head can have up to 9 very small staminate flowers. Produced in August and September, sometimes to November.
Pods are straight or slightly curved or flat except raised over seeds, and are 9 cm long, to 1 cm wide.
Cultivation details not known.
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.
Most wattles regenerate from seed after fire.
Acacia from Greek akis, meaning “a thorn” or “thorny”.
