Here, we present a revision of the west-central African genus Piptostigma of the tribe Piptostigmateae. Previous molecular phylogenetic analyses of Piptostigmateae have revealed that the genus as currently circumscribed is paraphyletic. The aims of the article are: (1) to clarify the generic delimitation of the genus Piptostigma, especially in relation to its current polyphyletic delimitation; (2) to provide a new updated key to the genera of tribe Piptostigmateae; and (3) to provide for the first time in over 100 years a complete taxonomic revision of genera Brieya and Piptostigma. Material and methods {\textendash} Normal practices of herbarium taxonomy were used for the morphological study of about 200 specimens from B, BR, BRLU, G, HBG, K, L, LBV, LISC, MO, P, U, US, WAG, YA and Z. We sequenced three plastid regions for 32 samples representing 26 ingroup (Piptostigmateae) and six outgroup species in order to explore the paraphyly of Piptostisma. The open source software QGis was used to generate the distribution maps of the species and their conservation status was obtained using the IUCN categories and criteria. Key results {\textendash} Molecular and morphological evidence support the reinstatement of the genus Brieya De Wild. Three keys are presented, one to the genera of Piptostigmateae and the two others to the species of Brieya and Piptostigma.

We use maximum parsimony, maximum likelihood and Bayesian phylogenetic reconstructions based on chloroplast DNA sequence data (matK, rbcL, trnL-F) to show that the remaining Polyalthia species segregate into three clades: a clade sister to Miliusa; a clade that also includes all Enicosanthum and Woodiellantha species sampled, sister to Neo-uvaria; and a clade that also includes all Haplostichanthus species sampled, inferred (based on previous research) to be sister to Popowia. Diagnostic morphological and anatomical characters are evaluated for the latter two clades, and diagnostic leaf and seed characters identified. Based on these results, the generic name Monoon is resurrected for the clade that includes Enicosanthum and Woodiellantha, following the transfer of 37 species from Polyalthia s.l., 18 species from Enicosanthum and the single Woodiellantha species.
