Nuytsia is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in Nuytsia. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele. Nuytsia is named after the monospecific genus Nuytsia, whose only species is Nuytsia floribunda, the Western Australian Christmas tree.
