A flora treatment for Ixora, the only genus of tribe Ixoreae (subfamily Cinchonoideae, family Rubiaceae), occurring in the Democratic Republic of the Congo, Rwanda and Burundi is provided. In this area, the genus is represented by thirteen native species, four of which are endemic. Five species are known from few collections only, resulting in some uncertainties about their taxonomic status. A further two Asian species can be found in cultivation. A key to the native species and full morphological descriptions are provided. Data on synonyms, distribution, habitat, vernacular names and uses are given; representative herbarium specimens and references to additional literature are cited. All species are accompanied by a botanical drawing, while characteristic features of the genus are also illustrated.
