Biology: Generally found in coastal sand dunes in colonies with both sexes present. Not known to be grazed.

Taxonomic notes: The specimens from Koonamore and Plumbago Station (EA) show similarities with A. quadripartita from the Gawler Ranges in the size and shape of leaves and the red stems but they differ from them only in the stellate indumentum. The intergradation of these two species led J. Black (1948) Flora of South Australia, p. 514 and some other botanists to regard them as being conspecific, with the name A. quadripartita having priority.
