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.

Psychotria elephantina Lachenaud \& Cheek is described as a new species. It is placed in P. sect. Involucratae (Petit) Verdc.,
endemic to the South West Region of Cameroon and is assessed as \‘ Endangered \’ (EN) using the IUCN criteria. Th e species
is distinctive in P. sect. Involucratae due to its long petioles (6.5 \– 12.0 cm), involucres of two pairs of large free bracts and
green corollas with included stamens in both longistylous and brevistylous fl owers.
