(Velloso) Verde (Haloragaceae), parrot's feather, is a rooted aquatic plant, with stems of up to 3 m long and leafy terminal shoots. The plant roots in shallow water to form a dense tangle of stems and roots. The shoots emerge 200-500 mm above the water surface (Cilliers 1999). The leaves of the plant are feathery and occur in whorls. The stem-boring weevil, (Hustache) (Coleoptera : Curculionidae), was next considered as the most promising additional biological control agent for the control of in southern Africa (Cilliers 1999).
