Plant Identification & Botanical Information Service

Please note there are changes to way the Plant Identification & Botanical Information Service will work while the National Herbarium of New South Wales is closed. The Herbarium collections are being digitised and the collection and staff are moving to new facilities at the Australian Botanic Gardens Mount Annan in 2021 (for more information see National Herbarium of New South Wales)
We will still provide a comprehensive plant identification and botanical information service and will still be accepting mail, email and phone enquiries. We will continue to also provide general botanical information including current scientific names of plants and details on the distribution of NSW plants. We will be endeavouring to keep up our usual standard of service but there is the possibility of delays due to our Digitisation Project and declining access to our collections.
Please note we will no longer be able to service over-the-counter enquiries. The Public Reference Collection (PRC) will be closed until we move the collection to the new building.

To determine the best way to prepare your specimens for identification please see Collecting Plant Specimens

For root identification, please see Root Identification (RID) as part of the Plant Disease Diagnostic Unit.

For urgent enquiries relating to poisonings from plants or mushrooms, contact the Poisons Information Centre on 13 11 26.
