Four new species of Sabicea (Rubiaceae) from tropical Africa are described and illustrated: S. desseinii from Cameroon, Gabon and Equatorial Guinea, S. ezangae from Gabon, S. jongkindii from Liberia and Ghana, and S. uniflora from Gabon. Their affinities are discussed, and the conservation status of each species is assessed. Sabicea speciosissima K.Schum. is excluded from the genus and synonymised with Rothmannia octomera (Hook.) Fagerl. Three other species are sunk into synonymy:  Sabicea gigantea Wernham with S. dewevrei De Wild., S. arachnoidea Hutch. & Dalziel with S. discolor Stapf, and S. neglecta Hepper with S. speciosa K.Schum.

Generic circumscriptions in tribe Vanguerieae (Rubiaceae) have been under discussion for a long time. Recent
molecular studies, while providing new insights, have not yet solved all the problems. In this study, the taxonomy
and phylogenetics of the genus Cuviera s.l. are investigated. On the basis of molecular and morphological evidence,
Cuviera is restricted to a group of ten West and Central African species. Globulostylis, previously included in
Cuviera, is reinstated as a distinct genus, with eight species from Central Africa. Both genera are revised; the
latter includes three new species (G. dewildeana, G. rammelooana and G. robbrechtiana) and two new combinations
(G. leniochlamys and G. uncinula). The close relationship of Cuviera s.s. and Globulostylis to Vangueriella is
shown. Six aberrant species (most from East Africa) are excluded from Cuviera, but further work is needed before
they can be confidently assigned to other genera.

A new species of Bertiera (Rubiaceae) from Equatorial Guinea and Cameroon, Bertiera rosseeliana Sonkd, Esono & Nguembou, is described and illustrated here. This new species belongs to subgenus Bertierella and appears to be closely related to Bertiera naucleoides. It differs from this species, however, by the features stated in the diagnosis: glabrous leaf blade (not puberulous); calyx lobes shorter (2-3 not 7-8 mm); corolla tube longer (18-20 not 5-6 mm); fruits without pedicel.
