The findings from these studies are being incorporated in a computer programme with numerous interacting options for using finely graded data to classify and analyse systematic structures and relationships. The programme is being applied to problems in the classification of the Bruniaceae. Taxonomic studies of groups in the Asclepiadaceae, Asphodelaceae, Bruniaceae, Ericaceae, Euphorbiaceae, Mesembryanthemaceae, Orchidaceae, Asteraceae, Restionaceae, Rhamnaceae, Poaceae, Rutaceae and Juncaceae are in progress. In addition, a study of the phylogeny at family level of the commelinoid monocots is in progress.
Data range from sequence data from the chloroplast DNA, to anatomy, embryology and morphology.
Analyses are largely based on parsimony methods. One study highlights a sympetalous dicot, while other studies are on Poaceae and Restionaceae. These studies also impact on theoretical definitions of species concepts. These studies have to date been focussed on the Poaceae and Restionaceae, and are directed at establishing the determinants of such traits in the fynbos and adjacent floras. This establishes a basis on which the incidence of endemism and extinction on the Peninsula can be determined.
