Taxonomy
editHillia 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]
Species
editThe following species list may be incomplete or contain synonyms.
Description
editMost of the species are slightly succulent epiphytes or small trees. A few are subshrubs or lianas. Hillia rivalis is a rheophyte. The tissues of all the species contain raphides. The capsules have a beak-like appendage.[6]
Uses
editHillia triflora is cultivated as an ornamental plant.[8]
