Rivers in Cameroon were surveyed to collect and document rheophytic plants. Rheophytes are the dominant aquatic macrophytes in tropical river systems, where they are adapted to extreme environments of rushing water (e.g., river rapids, waterfalls and flash floods). Rheophytic plants are useful indicators of river health. However, their habitats are threatened by human activities such as agriculture, plantation development, alluvial mining and dam construction, particularly in tropical countries. In this survey we documented 66 rheophytic species in 29 genera and 16 families. Two ferns, 8 monocotyledons and 56 dicotyledons were listed. Apart from the Podostemaceae family in which all species are rheophytic, the other 15 families have few species which are rheophytic. Five of these families have up to four species and the remaining 10 have only one member as a rheophytic species. The conservation status of each species is assessed and discussed. This work urges botanists, conservationists, and policy makers to do more to protect the habitats of rheophytes and put in place strategies and action plans for the conservation of this important biological group

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.
