NSW Herbarium

The National Herbarium of New South Wales houses the State reference library of 1.2 million preserved plants - our Herbarium collection. Click here to see an example of a herbarium specimen.

There are a number of services and facilities that support the Herbarium and our conservation & research programs:

  • Loans & exchanges - we belong to an international network that allows plant specimens to be loaned to other botanists or exchanged with other herbaria around the world
  • Processing plant specimens - collection, preparation & preservation of plant specimens and our volunteer program for assisting with preparation of higher plants, mosses, seaweeds and lichens for storage in the Herbarium and specimens for loans & exchanges
  • Guidelines for Herbarium visitors - entry policy guidelines
  • Plant Science Internship Program - advance working experience for undergraduates and recent graduates
  • Art and illustration - botanical illustration, Margaret Flockton award, Artist in Residence program, courses and exhibitions

Herbarium Collection

A herbarium is a collection of preserved plant specimens

The collection of the National Herbarium of New South Wales consists of over 1.1 million plant specimens. The majority are from within Australia. It is the largest collection in the world of the plants of New South Wales. The collection consists of plant specimens gathered by staff, as well as specimens from donations and exchange with other herbaria in Australia and overseas.

Herbarium specimens remain useful for study for hundreds of years, if properly cared for. Each specimen has a label recording its scientific name and where, when and by whom it was collected. The specimens provide information for scientific research into plant relationships, and they are a record of past and present plant distribution. This information is essential for making decisions about the conservation of our natural heritage.

The herbarium collection represents a comprehensive and accurate biodiversity record through time (as the flora changes) and space (representing the variation and distribution of species). This vital part of our scientific heritage requires expert scientific and technical curation. A key objective over the next few years is to unlock the rich store of information in the herbarium through databasing the collection information as part of Australia’s Virtual Herbarium.

Australia's Virtual Herbarium

Australia's Virtual Herbarium (AVH) is an on-line botanical information resource accessible via the Internet. This collaborative website provides immediate access to the wealth of data associated with the scientific plant collections held in each major Australian herbarium. Australian herbaria house over six million specimens that date from the earliest days of European exploration. They are the primary source of information of classification and distribution of plants, including algae, and fungi. In the future, the records of the AVH will be enhanced by images, descriptive text and identification tools.

Specimens in our Herbarium collection are arranged in a classification system based on R.M. Dahlgren (1980) Botanical Journal of the Linnaean Society 80: 91-124. Click here for the Sydney link to Australia's Virtual Herbarium.

Herbarium databases

53% of the Herbarium collection, including all vascular specimens collected in New South Wales, has been entered into the herbarium database ‘NSW Collections’ as part of the specimen curation process. All data processed specimens - usually herbarium sheets - are given a unique barcode to assist with the management of the collection. All incoming collections made by staff, and outgoing specimens sent on loan to other institutions, are data processed.

The PlantNET database, replacing the publication ‘Census of New South Wales Plants’ (Jacobs & Pickard 1981), continues to be checked against other records and newly accessioned specimens so that it is a current reference for staff, of the known distribution of species.

Using and maintaining the Herbarium collection

Our aims are to

  • enhance the usefulness of the collection by documenting and identifying specimens
  • increase the comprehensiveness and diversity of the collection as a resource for research and reference
  • carry out research using the collection, to improve our understanding of the relationships of plants to each other, and of their place in our environment.
