  abstract = {{A}im {I}n tropical {A}frica, savannas cover huge areas, have high plant species richness and are considered as a major natural resource for most countries. {T}here is, however, little information available on their floristics and biogeography at the continental scale, despite the importance of such information for our understanding of the drivers of species diversity at various scales and for effective conservation and management. {H}ere, we collated and analysed floristic data from across the continent in order to propose a biogeographical regionalization for {A}frican savannas. {L}ocation {W}e collated floristic information (specifically woody species lists) for 298 samples of savanna vegetation across {A}frica, extending from 18 degrees {N} to 33 degrees {S} and from 17 degrees {W} to 48 degrees {E}. {T}axa {W}e focused on native woody species. {M}ethods {W}e used ordination and clustering to identify the floristic discontinuities and gradual transitions across {A}frican savannas. {F}loristic relationships, specificity and turnover, within and between floristic clusters, were analysed using a (dis-)similarity-based approach. {R}esults {W}e identified eight floristic clusters across {A}frican savannas which in turn were grouped into two larger macro-units. {O}rdinations at species and genus levels showed a clear differentiation in woody species composition between the {N}orth/{W}est macro-unit and the {S}outh/{E}ast macro-unit. {T}his floristic discontinuity matches to the {H}igh (i.e. {N}&{W}) and {L}ow ({S}&{E}) division of {A}frica previously proposed by {W}hite () and which tracks climatic and topographical variation. {I}n the {N}&{W} savannas, the floristic gradient determined by rainfall was partitioned into the {S}udanian (drier) and {G}uinean (wetter) clusters. {W}ithin the highly heterogeneous {S}&{E} savannas and woodlands, six clusters were identified: {U}gandan, {E}thiopian, {M}ozambican, {Z}ambezian, {N}amibian and {S}outh {A}frican. {M}ain conclusions {T}he proposed pan-{A}frican classification of savannas and woodlands might assist the development of coordinated management and conservation policies.},
