Establishment of plant populations in novel environments may generate shifts in floral traits and plant mating systems.
High ploidy diversity and cytotype distribution in a biodiversity hotspot
The Greater Cape Floristic Region of southern Africa is a world biodiversity hotspot that has traditionally been considered depauperate in polyploid plants.
