Taxonomy
Hillia was named by Nicolaus Jacquin in 1760.[3][4] It was named for the English botanist John Hill (1716–1775).[5] Jacquin named only one species, Hillia parasitica. It has been suggested that the specific epithet as well as the generic name might well be a reference to John Hill.[6]
Some authors have placed five of the species in a separate genus, Ravnia. A cladistic analysis of morphological characters found Ravnia to be embedded within Hillia.[6] This hypothesis has not been tested with molecular data.
The genera Hillia, Balmea, and Cosmibuena form a monophyletic group. Some authors have designated this group as the tribe Hillieae, but it might be embedded within another tribe, Hamelieae.[7]
