Australian Plant Name Index (APNI)
The Australian Plant Name Index (APNI) is a tool for the botanical community that deals with plant names and their usage in the scientific literature, whether as a current name or synonym. APNI does not recommend any particular taxonomy or nomenclature. For a listing of currently accepted scientific names for the Australian vascular flora, please use the Australian Plant Census (APC) link above.
Comment:This combination is commonly attributed to G.Bentham, Edwards's Bot. Reg. 21: t. 1770, adnot. (1835). However, while Bentham listed Gratiola juncea Roxb. following his description of the genus Dopatrium in that work he did not definitely associate the genus name and specific epithet as required under ICN Art. 35.2 (Shenzhen Code, 2018).
