The correct identity of Lasiosiphon microphyllus (Meisn.) Meisn. (Thymelaeaceae) and the new combination Lasiosiphon kuntzei (Gilg.) R.Kolokoto & Magee.

Background While working towards a taxonomic revision of the genus Lasiosiphon (Thymelaeaceae), it became clear that the current application of the name Lasiosiphon microphyllus did not correspond to the identity of the type material. Objectives To effect the requisite nomenclatural changes. Method Herbarium specimens from NBG and PRE as well as the type collections of L. microphyllus and Lasiosiphon suavissimus were studied. Results Nomenclatural corrections are required for the taxa currently treated as L. microphyllus and L. suavissimus. Conclusions Lasiosiphon microphyllus is recognised as the earliest name for the tetramerous species currently known as L. suavissimus. Gnidia kuntzei is the earliest available name for the pentamerous taxon currently treated as L. microphyllus and the new combination Lasiosiphon kuntzei (Gilg.) R.Kolokoto & Magee is provided.
