Botanical literature shows a variety of names, including Lippia citriodora and L. triphylla. Verbena triphylla and Aloysia triphylla. A search of the taxonomic sources provides some clarification. It seems that the plant was first classified from specimens mainly growing in the Royal Garden at Madrid. A French botanist published a description in 1784, and a Spanish botanists in 1785, naming it Aloysia in honour of Maria Luisa, princess of Parma and wife of Charles IV of Spain. The plant was later found in the wild by botanists working in South America, who gave it the genus name Lippi, in memory of a French-born Italian naturalist, Augustin Lippi, murdered in Abyssinia in 1709.
