Acacia saligna (Port Jackson, Port Jackson willow) growing in farmland south of Malmesbury, Western Cape, South Africa and under attack by the gall-forming rust fungus that was introduced to South Africa as a biological control agent of this weed. [photos H.G. Robertson, Iziko ]

Native to western Australia. A Category 2 invasive plant in South Africa. The distinctive galls of the introduced rust fungus Uromycladium tepperianum are probably the easiest way of identifying this plant.
