Two subgenera of Combretum Loefl. occur in the Flora of southern Africa (FSA) region. Previous sectional classifications
were assessed in view of molecular evidence and accordingly modified. Ten sections in subgen. Combretum, 25 species
and eight subspecies are recognized. Subgen. Cacoucia (Aub!.) Exell & Stace comprises four sections and seven species. C.
engleri Schinz, C. paniculatum Vent. and C. tenuipes Eng!. & Diels are reinstated as distinct species separate from C. schumannii
Eng!., C. microphyllum Klotzsch and C. padoides Eng!. & Diels, respectively. C. schumannii occurs outside the FSA
region. Records of C. adenogonium Steud. ex A.Rich., C. platypetalum Welw. ex M.A. Lawson subsp. oatesii (Rolfe) Exell
and subsp. baumii (Eng!. & Gilg) Exell in Botswana are doubtfu!. C. celastroides Welw. ex M.A.Lawson subsp. orientale
Exell is elevated to species level as C. patelliforme Eng!. & Diels. C. grandifolium F.Hoffm. is reduced to C. psidioides Welw.
subsp. grandifolium (F.Hoffm.) Jordaan. Twenty-six names are lectotypified. The type, a full synonymy, other nomenclatural
and taxonomic information, the full distribution range and a distribution map are provided for each taxon. Selected specimens
examined are given for poorly known species. Keys to subgenera, sections and species are provided.
