Prostanthera schultzii was first formally described in 1896 by Ralph Tate from an unpublished description by Ferdinand von Mueller and the description was published in Report on the work of the Horn Scientific Expedition to Central Australia. The type specimens were collected on the "higher slopes of Mount Sonder".{{cite book |last1=Tate |first1=Ralph |title=Report on the work of the Horn Scientific Expedition to Central Australia |date=1896 |publisher=Dulau 1896 |location=London |page=173 |url=https://www.biodiversitylibrary.org/item/111776#page/205/mode/1up |access-date=22 September 2020}}{{cite web|title=Prostanthera schultzii|url= https://id.biodiversity.org.au/instance/apni/543553|publisher=APNI|access-date=22 September 2020}} In 1976, John Carrick changed the name to Wrixonia schultzii but in 2012 Trevor Wilson, Murray Henwood and Barry Conn changed the name back to P. schultzii.{{cite journal |last1=Wilson |first1=Trevor C |last2=Henwood |first2=Murray J. |last3=Conn |first3=Barry J. |title=Status of the genus Wrixonia F.Muell.
