Botanical Identification Service

** Due to the COVID-19 pandemic, there are changes to the way we receive postage and the BIS team is often working off-site. There may be delays in processing your enquiry. Please ensure all plant specimens are pressed and dried prior to posting. Thank you for your patience and understanding. **
The National Herbarium of New South Wales is closed to the public, as we are digitising the collection and staff are preparing our move to new facilities at the Australian Botanic Gardens Mount Annan in 2021 (for more information see National Herbarium of New South Wales). Consequently, there are changes to the Botanical Identification Service. We are closed for in-person enquiries and the Public Reference Collection (PRC) is unavailable to visitors.

We continue to provide a comprehensive identification service, with emphasis on wild (native and naturalised) and cultivated plants of New South Wales.

The specimens we receive and retain through the Botanical Identification Service make a significant contribution to our knowledge and understanding of the New South Wales flora. They become a permanent record in the herbarium providing invaluable data on the distribution and ecology of our flora. This data contributes to resources such as NSW FloraOnline (PlantNET), Australasian Virtual Herbarium and Atlas of Living Australia.  
The identification of plant specimens can be difficult and at times requires a considerable amount of time and effort. In order to give you accurate identifications we require well-collected specimens with adequate accompanying information. To determine the best way to prepare your specimens for identification please see our printable booklet on collecting plants
Please print, complete and submit this form with your plant specimens: Botanical Identification Service Enquiry Form (PDF)
Before you collect, please ensure you have permission. An appropriate licence is required prior to collecting plant specimens from land managed by National Parks and State Forests in New South Wales. Permission should always be sought from the landowner and/or manager when collecting specimens on private land. The collection of species listed under the Biodiversity Conservation Act 2016 requires a licence – see Licence to pick or harm a threatened species or ecological community. Please provide permit/licence details with your plant specimens.
