The Australian National Herbarium is at the National Botanic Gardens. The Herbarium houses the largest collection of pressed, dried plant specimens in Australia. The Herbarium is operated jointly with the CSIRO as part of a joint research facility, the Centre for Plant Biodiversity Research. It is not open to the public. The Australian National Herbarium is participating in the creation of Australia's Virtual Herbarium (AVH), a web based record of botanical information. This includes six million specimen records displaying geographic distribution, images, descriptive text and identification tools.
