The Board of the Botanic Gardens and State Herbarium oversees the State Herbarium of South Australia and three botanic gardens (Adelaide Botanic Garden and Botanic Park, Mount Lofty Botanic Garden and Wittunga Botanic Garden) in conjunction with the South Australian Department of Environment, Water and Natural Resources.

The State Herbarium of South Australia is the fourth largest herbarium in Australia, containing more than one million plant specimens. It is the centre for preservation and generation of knowledge of native and naturalized plants, algae, lichens and fungi in South Australia. The State Herbarium publishes the Journal of the Adelaide Botanic Gardens, the Flora of South Australia, handbooks and other publications, and provides information on South Australia’s plants online (http://flora.sa.gov.au/).
