Hillia is a genus of flowering plants in the family Rubiaceae. It has 24 species.[1] All are indigenous to tropical America.[2]

Most 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.[3]

Hillia triflora is cultivated as an ornamental.[4]

Hillia was named by Nicolaus Jacquin in 1760.[5][6] It was named for the English botanist John Hill (1716-1775).[7] 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.[3]

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.[3] 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.[8]

gollark: The calculululus thing?

gollark: Bees.

gollark: Think about it. Wouldn't *you* like Minoteaur existence?

gollark: I am unfortunately generally too incompetent to create it, but I need it to exist, for purposes.

gollark: Or make Macron make Minoteaur.
