Hymenachne amplexicaulis
Hymenachne is a semi-aquatic perennial grass that has become a major weed of wetlands, flood plains and sugar cane crops of northern Australia.
Originally introduced to Queensland and the Northern Territory as a ponded pasture species, it has invaded freshwater wetlands, flood plains and river banks. It forms dense infestations, displaces native plant species, reduces biodiversity and threatens native wetland habitat.
