Abstract

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.
