Celtis occidentalis L.
American hackberry, common hackberry, hackberry, nettletree, northern hackberry, sugarberry, western hackberry
Native to North America (i.e. Canada and the eastern and central parts of the USA).
Naturalised in some coastal and sub-coastal regions of eastern Australia. It has a patchy distribution from sub-coastal south-eastern Queensland (i.e. near Toowoomba), southwards through eastern New South Wales (i.e. in the central western slopes, central coast and southern tablelands regions) and the ACT, to near Albury in southern New South Wales.
This species is an occasional garden escape that has chiefly become naturalised along the banks of rivers in New South Wales. It is currently regarded as a "sleeper weed" or minor environmental weed in south-eastern Australia.
