*LoM, *MuF, *MuM, *MSB, *RobP, *VRiv, *Wim. Naturalised all mainland States. Native to Mediterranean region, Asia. Occurs in clay soil in shallowly inundated areas (e.g. Hattah Lakes, Lake Wallawalla, Kerang, Natimuk areas).
Fibre from A. theophrasti was used in the Americas and India for the manufacture of string, rope and fishing nets, and in addition the oil from the plant can be used as a food source or in the manufacture of soap. It seems likely that this aggressive plant may have been deliberately introduced in the 1800s for these purposes.
