Plant Identification & Botanical Information Service

We provide a comprehensive plant identification and botanical information service either over-the-counter (open weekdays 10 am to 1 pm) or by mail, email or fax. We also provide general botanical information including current scientific names of plants and details on the distribution of NSW plants. The Botanical Information Service also maintains the PRC (Public Reference Collection) which is available for members of the public to access. The PRC is a useful resource which aims to have a representative specimen of each New South Wales native and naturalised plant species.

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.
