For every weed index below, developed through IEWF, you get 4 choices as to how to reach the weed information. If you are more comfortable with common names you can choose the common name index for the area otherwise use the scientific name index. For those of you with restricted computer resources you can choose the index without photos or if you don't care have a look at the index filled with weedy photos. If you want to just find a weed at no specific location try "Weeds in Australia" indexes. For an area developed independent to IEWF you will be linked to a site for that region.
When you have found your plant take note of the scientific name (1st part of name is genus, 2nd is species) and click here to go to Australia's Virtual Herbarium , developed by the various herbaria around Australia and DEH, to see distribution maps.
We hope you enjoy using our easy web weed lookup for assistance in weed identification!
