Abstract

Frithia N.E.Br (Mesembryanthemaceae), formerly thought to be a monotypic genus, has been found to comprise two species. Populations from the eastern parts of the distribution range of Frithia pulchra N.E.Br. are recognised as a distinct species,  Frithia humilis PM Burgoyne The genus has a limited distribution, although present in three provinces of South Africa, namely Gauteng, North-West and Mpumalanga. The two window-leaved species are allopatnc and morphological differences between the roots, leaves, flowers, pollen, capsules and seeds are discussed. A formal description of the new species, an identification key and a distribution map of the two species are provided.
