Pollen limitation (mean ± s.e. log response ratio) for (a) self-compatible and self-incompatible species in South Africa and the rest of the world, (b) autofertile, pollinator-dependent self-compatible and self-incompatible species in South Africa. Different letters above bars indicate that treatments are significantly different. Numbers above bars indicate sample size (number of species). Slightly different datasets were used for South Africa in (a) and (b) (see Material and methods section). Inset shows position of study region, comprising the Greater Cape Floristic Region (GCFR) and South-Eastern Summer Rainfall Region (SESRR), within South Africa.
