Salvinia molesta, yes, banned invasive. Put it on your compost heap and do not distribute. It has definite invasive potential, so please be responsible with this plant. It is often still found in garden ponds where it is managable, but if this gets onto a dam, then could have the same effect at the water hyacinth is having on Hartebeespoort Dam.

Kind regards,
