Scientific classification

Type species
Machaonia acuminata
Humboldt & Bonpland

Machaonia was named by Humboldt and Bonpland in 1806 in their book, Plantae Aequinoctiales.[4][5] This genus name is for Machaon, the son of Asclepias in Greek Mythology.

Phylogenetic studies of DNA sequences have shown that Machaonia is paraphyletic over Neoblakea and Allenanthus.[6]
