The
original specimen was collected at
Sydney in the early colonial days. This species first appeared in the scientific literature as
Rhagodia hastata in 1810 in the
Prodromus Florae Novae Hollandiae, authored by the prolific Scottish botanist,
Robert Brown. In 1978,
Andrew John Scott made the combination
Einadia hastata. After phylogenetical research, Fuentes-Bazan et al. (2012) included this species in genus
Chenopodium, as
Chenopodium hastatum (R.Br.) S. Fuentes & Borsch., but this name was a later homonym and thus illegitimate. In 2017, Iamonico & Mosyakin replaced it by the name
Chenopodium robertianum, honouring the botanist Robert Brown. ==References==
