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.

Based on a careful examination of more than 700 herbarium specimens and field investigation, a comprehensive revision of the genus Massularia is given. Massularia stevartiana, a new species from Central African Republic, Cameroon and Gabon is described and illustrated. The novelty is distinguished from M. acuminata, the only other species previously recognized in the genus, by its smaller leaves and flowers. For the two species recognized we provide a morphological description, distribution, habitat, phenology and IUCN conservation status assessment. Distribution maps and a dichotomous key are also provided

As a result of ongoing studies of the Rubiaceae of Gabon, the new species
Colletoecema gabonensis is here described and illustrated. It is endemic to Gabon,
where it is the only species of the genus, and is so far only known from three collections
from the Ogooué-Lolo and Ngounié provinces. The new species is morphologically
intermediate between its two congeners, C. dewevrei (from Cameroon, Central
African Republic, Republic of the Congo, DR Congo, and Angola) and C. magna
(endemic to Cameroon). The new species agrees with C. dewevrei in having flowers
with exserted anthers and style, but differs in its sessile flowers and fruits. In the latter
characters, it resembles C. magna, from which it can be separated by its smaller fruits
and leaves, and by its different floral morphology. An IUCN conservation assessment
has been made and the species is provisionally assessed as Vulnerable, based on its
restricted area of occupancy and the small number of known locations
