Lagynias was a genus of flowering plants in the family Rubiaceae but is no longer recognized. In 2005, it was sunk into synonymy with Vangueria, based on a phylogenetic study of DNA sequences.
Robynsia is a monotypic genus of flowering plants in the family Rubiaceae. It was described by John Hutchinson and was named after his friend and colleague Walter Robyns. The genus contains only one species, Robynsia glabrata, which is found in Ghana, Ivory Coast and Nigeria. The species is morphologically similar to the genus Cuviera but differs by having long, slender corolla tubes.
Rytigynia is a genus of flowering plants in the family Rubiaceae. It is found in tropical and southern Africa. The genera Rytigynia and Fadogia form a strongly supported clade but neither of these genera is monophyletic.
Tapiphyllum was a genus of flowering plants in the family Rubiaceae but is no longer recognized. In 2005, a molecular phylogenetic study showed that the type species, Tapiphyllum cinerascens, is more closely related to Vangueria than to Tapiphyllum obtusifolium and Tapiphyllum velutinum. It is not clear whether the latter two species are really separate from Vangueria. All the species of Tapiphyllum have been sunk into synonymy with Vangueria.
