A beachcomber's notes on bitou bush (Chrysanthemoides monilifera subsp. rotundata (DC.) Norl.) in Queensland
George N. Batianoff, Queensland Herbarium, Department of Environment, Indooroopilly, Queensland 4068, Australia.
Chrysanthemoides monilifera subsp. rotundata (DC.) Norl. (bitou bush) has been recognised as an invasive exotic weed of major concern along the east coast of Australia since the 1970s. Sea hydrochory (ocean currents) dispersal of bitou bush propagules is believed to play an important role along the Gold Coast. Weed control operators along the coast are advised to be aware of intermittent establishment of bitou bush along beachfronts.
