Belongs within: Rubioideae.

The Coussareeae are a small but morphologically diverse group of flowering plants found in the Americas, many of which have tetramerous flowers, flattened berry-like or thin-walled capsular fruits, and flattened seeds (Bremer & Manen 2000).

Characters (from Bremer & Manen 2000): Herbs (creeping in Coccocypselum), subshrubs, shrubs, or small trees. Stipules entire, cleft, as a ridge with appendages, or deeply bilobed. Flowers homo- or heterostylous, often tetramerous, white, blue, or bright yellow (Cruckshanksia, Oreopolus). Ovary 1–2-1ocular, with 1–2 or many (Coccocypselum) ovules per locule. Fruits often flattened (not Coccocypselum), fleshy, white (Coussarea) or often blue (Faramea, Coccocypselum) berries, schizocarps (Declieuxia), or thin-walled capsules (Cruckshanksia, Oreopolus), with 1–2 or many seeds, often flattened. Pollen 3-colporate or 2–4-porate. Chromosome basic number x = 10, 11? with 2- or 4-ploidy level.
