State Herbarium of South Australia

The State Herbarium of South Australia, sometimes called the South Australian Herbarium, and having the herbarium code, AD, is located in Adelaide, South Australia. It is one of several State and Commonwealth herbaria in Australia. The Department for Environment and Water is the state agency which is responsible for the Herbarium, but the Board of the Botanic Gardens and State Herbarium (established by an Act of Parliament, most recently the Botanic Gardens and State Herbarium Act 1978) is charged with its establishment and maintenance.

The Herbarium publishes for the electronic Flora of South Australia FloraSA and the Census of South Australian plants, algae and fungi. It also publishes the journal, Swainsona (formerly Journal of the Adelaide Botanic Gardens).
