Retiniphyllum is a genus of flowering plants in the family Rubiaceae and contains 20 species. It is the only genus in the tribe Retiniphylleae. The representatives are shrubs or small trees that grow in white sand soils in tropical South America. They are mainly distributed in the Guayana Region (Venezuela) but also occur in the Amazon Basin, the eastern Andes and central and eastern Brasil.

== Description == The species exhibit a character that is not common in the family Rubiaceae, viz. the presence of two collateral and pendulous ovules per locule. The shrubs or trees have apical buds with abundant resin. Each flower is subtended by a bracteole and the corollas are contorted. Stamens are reflexed in anthesis and have basal and apical sterile appendages. Many species also exhibit secondary pollen presentation. The 5-locular ovary contains two ovules per locule. The drupaceous fruits contain pyrenes with one seed due to the abortion of one ovule.
