    • Taxonomy: (Gmel) Kuntze
    • Presence: Nationally eradicated, first record from Whangaparaoa, Auckland in 1988
    • Habitat: Only known from a farm dam and ornamental ponds, but also grows in slow flowing waters overseas
    • Notes: Problem weed in still and flowing water bodies, fortunately detected and eradicated before establishing as a naturalised species.
    • Propagation: Vegetative spread by stoloniferous growth and by floating seeds which are fringed with many bristles. Huge potential for spread because seeds are adapted for water bird dispersal. Also deliberate plantings
