| A taxonomic revision of the genus Desmopsis is presented. Within the genus Desmopsis 25 species are recognized, 9 of which are new, with one new combination. Distinguishing morphological characteristics are discussed, and a dichotomous key to all species is given. The species treatments include descriptions, full synonymy, geographical and ecological notes, vernacular names, and taxonomic notes. Distribution maps are presented of all species, and a complete identification list of exsiccatae examined is included. |

| The amphi-atlantic genus Mendoncia of the Acanthaceae counts c. 80 species. In tropical Africa it is represented by 14 species, eight in continental Africa and six in Madagascar. The remaining species occur in tropical America. The new species Mendoncia camerounensis and M. rabiensis are described and illustrated. Mendoncia floribunda is resurrected, fully described, and illustrated as well. Mendoncia iodioides, reduced to a variety of M. phytocrenoides in the Flore du Gabon, is restored as a distinct species. The isolated western population of Mendoncia gilgiana is recognised as a new subspecies. The conservation status of all species is assessed. Only a few of them are classified as Least Concern, the others as ranging from Critically Endangered to... |

| Four new species, one with two subspecies, of the genus Campylospermum are described, all endemic or sub-endemic to Gabon. These are C. auriculatum, C. gabonensis, C. gabonensis subsp. australis, C. glaucifolium and C. occidentalis. Distribution maps and scans of the holotypes are provided as well as preliminary IUCN Red List assessments. New combinations for nine species formerly assigned to the genus Ouratea and/or Gomphia are proposed: C. andongensis, C. glomeratum, C. longestipulatum, C. lunzuensis, C. lutambensis, C. nutans, C. plicatum and C. warneckei. Finally, one taxon is raised from the variety to species level, leading to the new combination C. costatum. |

| A taxonomic revision of the African genera of Costaceae (Costus and Paracostus) is given. Within the genus Costus 24 species are recognized, 8 of which are here described as new and one is given a new name. Included are chapters on the history of the taxonomy of the family, morphology, flower biology, pollination, dispersal, distribution, ecology, phylogeny and molecular studies and conservation. The species treatments include descriptions, full synonymy, geographical and ecological notes and taxonomic notes. For all species distribution maps are provided. A complete identification list with all exsiccatae studied and an index to scientific names is included at the end. |
