Recent molecular phylogenetic results have demonstrated thatMonechmas.l., a group of plants with ecological importance in the savanna and succulent biomes of sub-Saharan Africa, is polyphyletic with two discrete lineages recognisable. In the present work, we recogniseMonechmaGroups I and II at the generic rank, which can be distinguished by differences in inflorescence characteristics and seed morphology. The nomenclatural implications of these findings are investigated. The lectotype ofMonechma,M. bracteatumHochst., is a part of a small lineage of plants closely allied toJusticiaL. sect.Harnieria(Solms) Benth. for which the earliest valid name is found to beMeiospermaRaf. Hence,Monechmais synonymised withinMeiosperma, which comprises six accepted species and two undescribed taxa. The majority of species of formerMonechmas.l. are resolved within the second lineage for which the only validly published generic name isPogonospermumHochst. This resurrected genus comprises 34 accepted species plus two undescribed taxa.Pogonospermumdisplays considerable morphological variation and is here subdivided into six sections based primarily on differences in plant habit, inflorescence form, calyx, bract and bracteole venation, and seed indumentum. The new combinations and new sections are validated, and seven accepted species names are lectotypified.
