This work reconstructs the historical biogeography of the four lineages of Disa, Irideae p.p., the Pentaschistis clade and Restionaceae, and finds that tropical taxa are nested within a predominantly Cape clade.
Geographical affinities of the Cape flora, South Africa
The hypothesis that a relatively small number of clades that have been proposed as ‘Cape clades’ share a common time of differentiation from their geographical neighbours is tested.
A novel supermatrix approach improves resolution of phylogenetic relationships in a comprehensive sample of danthonioid grasses.
A Generic Classification of the Danthonioideae (Poaceae)1
A new generic classification of the largely Southern Hemisphere grass subfamily Danthonioideae is presented, based on an almost completely sampled and well-resolved molecular phylogeny and on a complete morphological data set, which recognizes 17 genera, including five new genera.

The grass subfamily Danthonioideae is one of the smaller in the family and the relationships at the base of the subfamily are clearly established, comprising a series of three clades of Merxmuellera species.
The Migration of the Palaeotropical Arid Flora: Zygophylloideae as an Example
For the recruitment of the arid Palaeotropical flora, the preponderance of migrations across the African continent points to a repeated pattern of dispersal mediated by periodically more contiguous habitat, the so called ‘African arid corridor,’ with rarer long distance dispersal events between other disjunct areas.
THE PHYLOGENY OF THE PENTASCHISTIS CLADE (DANTHONIOIDEAE, POACEAE) BASED ON CHLOROPLAST DNA, AND THE EVOLUTION AND LOSS OF COMPLEX CHARACTERS
It is proposed that both glands and sclerophyllous leaves act as defense systems against herbivory, and a cost/benefit model is built in which multicellular glands or sclerophical leaves are lost when the alternative defense system evolves.
New species and taxonomic changes within Pentaschistis (Danthonioideae, Poaceae) from Western Cape, South Africa
Three new species of Pentaschistis (Nees) Stapf are described from the Cape Floristic Region. P. trifida . P clavata and P. horrida . The former has been collected from inland ranges of the Cape Fold…
