The phylogeny of the genus Moehringia (Caryophyllaceae) is investigated by means of analyzing nuclear (ITS) and chloroplast (matK) sequence data in combination with morphological characters. Parsimony and Bayesian methods yield consistent results, an

Previous phylogenetic studies in the Arctotideae-Gorteriinae (Asteraceae) have found support for a Gorteria clade. The results also indicated Hirpicium to be paraphyletic, whereas Gorteria and Gazania were found to be monophyletic. Previous investiga

Aim The Cape region is known for its exceptional species richness, although much remains unknown regarding the appearance of the modern Cape flora. One explanation is that floral diversification was influenced by the establishment of winter rainfall/

The new species Metalasia namaquana is described from the Kamiesberg, a well known centre of plant endemism in the Northern Cape Province of South Africa. The species is most similar to Metalasia fastigiata and Metalasia albescens. The morphology, ec

Asteraceae are the largest family in southern Africa. Elucidating its origins and radiation in the region requires well-supported species-level phylogenies of the lineages. This paper presents a phylogenetic framework for subtribe Arctotidinae, which

The phylogeny of subtribe Gorteriinae (Asteraceae-Arctotideae) is investigated by means of cladistic analysis of morphological characters. Two sister groups are formed, namely a Gorteria clade also containing Hirpicium and Gazania, and a Berkheya cla
