Threatened floral kingdoms

There are six floral kingdoms, namely the Boreal, Palaeotropic, Neotropic, Cape, Australasian and Antarctic, all cover huge areas, sometimes spanning two continents. The Boreal kingdom occupies 40 percent of the world's surface, where as the Cape (or fynbos) only covers about 0.04 percent. This small area is even more diverse in plant life than the richest parts of the Amazon.
