Acacia sp. in Black Hill, Morialta and Horsnell Gully Conservation Parks

PROTEACEAE

The name comes from the genera Protea, and refers to the Greek sea-god Proteus, who had the ability to change shapes; referring to the diversity within that genus.

There are bout 1,500 species in 75 genera, extending into the tropics, mostly of the Southern Hemisphere of these there about 900 species, 45 genera in Australia.

Pollination of most species in this family is through insects, birds or mammals, and the flowers are arranged in a special manner to facilitate this.

Many plants in the Proteaceae family also have special root structures known as 'proteoid roots' These are special mop-like growths which help the plants absorb nutrients. Members of the Proteaceae family tend to be susceptible to Phytophthora cinnamomi and other root rotting pathogens.

Fire response
It is said that this plant can be fire sensitive and confidence in it surviving a fire event is low. But it can survive fire in some situations through regrowth from basal stems, lignotuber or roots. Burnt plants take a long time to reach maturity again once burnt. Seeds need a disturbed site with competition removed to establish, therefore there is low confidence that the plants will become established in a new location.
