Comprising a land area of ca 90000 km2, less than 4% of the total land area for the Southern African subcontinent, the Cape Floristic Province is one of the world's richest areas in terms of botanical diversity for its size. An estimated 8650 species of vascular plants occur in this area, about 65% of which are endemic. This is about 42% of the estimated total for all of southern Africa. The number of species packed into so small an area is remarkable for the temperate zone, and compares… 
Plant Diversity of the Cape Region of Southern Africa
Species richness of the Cape flora is hypothesized to be the result of geographic and parapatric radiation in an area with a mosaic of different habitats due to local soil, climate, and altitudinal differences that combine to produce steep ecological gradients.

There is a great need for experimental testing of the proposed speciation mechanisms, more molecular clock estimates of the age and pattern of the radiations, and more fossil evidence bearing on the past climates.

It is argued that six floras, with distinct geographical centres, different extra-African affinities, ages of radiation and radiation rates, can be delimited: the Austro-temperate, Tropic-alpine, Lowland forest,tropic-montane, Savanna and Arid Floras.

A phylogenetic analysis of an almost complete species sample of the largest clade of Restionaceae, the third largest Cape clade, indicates that the radiation of the Restion Families started between 20 and 42 Myr ago, and since then there were no, or at most gradual, changes in the speciation rate in this clade.
Conservation of the invertebrate fauna on the Cape Peninsula
Fynbos had a higher beta diversity of epigaeic invertebrates than forests, so the conservation of as much of the disturbed and fragmented lower elevations as soon as possible is needed.
Conservation status of large branchiopods in the western Cape, South Africa
Temporary wetlands are an ecologically and economically important habitat in South Africa. They harbor large branchiopods, known to be flagship species of nonpermanent aquatic habitats, and sensitive
Testing the prediction that the evolution of the species richness in the two areas followed a similar temporal progression by comparing the rates of lineage accumulation for African and Australian Restionaceae suggests that this acceleration in the speciation rate continued in the African clade, whereas the Australian clade retained a constant diversification rate.
Pentaschistis (Poaceae) diversity in the Cape mediterranean region: habitat heterogeneity and climate stability
Aim To evaluate the role of habitat heterogeneity on species richness and turnover in the mega species-rich Cape Floristic Region (Cape), the mediterranean region of southern Africa. Location The
Montane Refugia for Endemic and Red Listed Dragonflies in the Cape Floristic Region Biodiversity Hotspot
The results here show that at the reserve scale in this global hotspot there can be remarkable concordance, suggesting further studies on other taxa should be carried out to determine the full extent of taxonomic concords in this irreplaceable area.
Continental scale patterns of biodiversity: can higher taxa accurately predict African plant distributions?
Higher taxa appear to provide a powerful and accurate tool that can be used to predict large scale patterns of species biodiversity in Sub-Saharan Africa, however care must be taken when using taxa higher than genera, especially if selecting areas of highest conservation priority.


Plant species diversity in cape fynbos: Gamma and delta diversity
The results support the conventional view that fynbos plant diversity is partly a consequence of the peculiar geography of the zone, and of palaeo-climatic change, which have favoured geographic speciation.

Endemism and speciation in a lowland flora from the Cape Floristic Region
An analysis of the frequency of biological traits associated with species with different categories of endemism enabled the establishment of a biological profile of a local endemic: a dwarf to low, non-sprouting shrub with soil stored seeds which are ant-dispersed and/or form a symbiotic relationship with microbes.
On Alpha Diversity and the Richness of the Cape Flora: A Study in Southern Cape Fynbos
The Cape floristic region is very rich in species with a high proportion of endemics (Goldblatt 1978; Taylor 1978). Most speculation on the origin of fynbos (and Australian heathland) diversity has

The flora of the Sahel is rather poor, i.e. approximately 1500 species of flowering plants for an area of 3 million km2. The flora is typically paleotropical. The richest families are: Poaceae,
Analysis of the size and composition of the southern African flora
The southern African flora has been surveyed for the first time at species level in the List of Species of Southern African Plants (Gibbs Russell e tal., 1984). The numbers of taxa recorded for
Changes in Plant Community Diversity and Floristic Composition on Environmental and Geographical Gradients
The predictability of the fioristic compositions and diversities of tropical forest plant communities eems strong, albeit circumstantial, evidence that these communities are at ecological and perhaps evolutionary equilibrium, despite indications that certain aspects of their diversity are generated and maintained stochastically.
Some Thoughts on Resource Competition and Diversity in Plant Communities
In a broad variety of plant communities — in temperate and tropical regions, in grasslands, forests, lakes, rivers, estuaries, and the oceans — plant species diversity within a geographical area is locally higher in habitats relatively poor in nutrients, and lower in sites very poor, or richer in nutrients.

Very high tree species richness seems to be a general property of mature lowland evergreen forests on fertile to moderately infertile soils on all three continents.
