An upright or arching shrub (usually growing 3-5m tall) with many branching stems. Younger branches are reddish-brown with fine hairs; older branches become hairless and turn grey or dark brown. It is a significant environmental weed that forms thickets under tall trees, and dense infestations will shade the indigenous ground flora and impede the regeneration of overstorey plants.
