Barleria grootbergensis I. Darbysh. & E. A. Tripp is described from the Grootberg Pass in Kunene Region, Namibia. Its affinities within Barleria sect. Somalia are discussed. A second taxon, named as Barleria galpinii C. B. Clarke in the Prodromus einer Flora von SüdwestAfrika, is reassessed and found to be referable to B. pseudosomalia I. Darbysh., a species previously known only from central Tanzania. A revised checklist to the Barleria of Namibia is presented.
