Two new species of Brownanthus , B glareicola Klak and B fratemus Klak and one new species of Scopelogena , S. bruynsii Klak are described. S. gracilis L.Bolus is reduced to synonymy under S . verruculata (L.) L Bolus. Three new combinations are made: Antimima excedens (L.Bolus) Klak. Erepsia dunensis (Sond.) Klak and Hammeria meleagris (L.Bolus) Klak and full synonomy is given  Lampranthus maximilianii (Schltr. & A.Berger) L Bolus is transferred back to Braunsia maximilianii (Schltr. & A…

New combinations, a new genus and five new species in the Aizoaceae
It is shown that several of its species are more closely related to other taxa within the Aizoaceae than they are to Lampranthus, and anomalous species are transferred to the genera Esterhuysenia, Oscularia, Antimima, Erepsia and Ruschia.
Eight new species of Aizoaceae from the Cedarberg and Namaqualand, South Africa
The shrubby members of the Mesembryanthema are still poorly known and further field work and study of herbarium material has led to the recognition of eight new species, which are placed in the Ruschioideae.
Notes on Ruschia dichroa (Aizoaceae): An Endemic to the Arid Mountain Fynbos of the Western Cape, South Africa
Ruschia dichroa differs from both A. longifolia and R. marianae by the finely serrated keels on its leaves, which are smooth in the other two species, and from A. Schwantes and AstridiaLongifolia by the presence of filamentous staminodes.
Two new Oxalis (Oxalidaceae) species from the Richtersveld National Park, South Africa
Two new Oxalis species from the Richtersveld National Park (South Africa) are described and typified andPhylogenetic analyses based on nuclear ITS and plastid trn SG data confirmed the placement of both of these species within a clade containing O. pes-caprae.
A Gordion knot in Ruschioideae (Aizoaceae): Acrodon and Brianhuntleya in an attempt to disentangle the confusion
Summary: The confusion of names and species boundaries in and between the genera Acrodon and Brianhuntleya, resembling a Gordion knot, is analysed on the base of new collections, images from habitat
Niche specificity influences gene flow across fine‐scale habitat mosaics in Succulent Karoo plants
It is suggested that edaphic specialisation, coupled with highly restricted seed and pollen dispersal in heterogeneous landscapes, has played a major role in driving rapid diversification at small spatial scales in this hotspot system, despite the fact that these factors do not influence all organisms uniformly.

Miscellaneous taxonomic notes on Aizoaceae
Summary: In preparation for the treatment in the Lexicon of Aizoaceae, the circumscription and species composition of several genera are reviewed: Acrodon, Amphibolia, Arenifera, Ebracteola,
New combinations in Ruschioideae, based on studies in Ruschia (Aizoaceae)
It is shown that a number of species in both big genera Ruschia and Lampranthus do not conform with the critical features of the genera, and these deviating species are placed in thegenera Amphibolia, Cerochlamys, Eberlanzia, Erepsia,Esterhuysenia, Octopoma, Oscularia, Rhombophyllum, and Zeuktophyllums.
New combinations in Antimima (Ruschioideae, Aizoaceae) from southern Africa
As a consequence of the emended description of Antimima N.E.Br. by Dehn (1989) and based on extensive comparison of all types of the genera Antimima and Ruschia Schwantes, and on studies of about 250
