Abstract
Lasiosiphon Fresen. (Thymelaeaceae: Thymelaeoideae) is now understood to be a morphologically diverse genus distributed across southern and tropical Africa, Madagascar and India. The taxonomic history of Lasiosiphon has been marked by several revisions in its circumscription and status, particularly regarding its relationship with Gnidia L. Our phylogenetic analysis of nuclear (ITS) and plastid (matK, rbcL, rps16 and trnL-F) regions of an expanded sampling of the tropical African species of Gnidia provides compelling evidence for including all the tropical African species of Gnidia in Lasiosiphon. The morphological characters of these species are consistent with this conclusion. We accordingly provide 29 new combinations in Lasiosiphon for species of Gnidia that currently lack combinations in that genus. We also provide a comprehensive nomenclature of all currently recognized Lasiosiphon species at the regional level worldwide, as the framework for future taxonomic revisions in the genus.
