Pantropical
As pantropisch ( gr. Pan "general", "pan-") to affinity groups (referred taxa ) of living beings, their distribution, the tropical and subtropical includes zones of all continents.
In geobotany , however, only the flora- rich Palaeo- and Neotropic are combined; the third tropical flora kingdom, the Australis , is not included in the strict sense. Many families of tropical flowering plants are pantropical (well-known examples are the bay , pepper , mulberry , mimosa , myrtle , ebony , acanthus , aralia and arum plants as well as the palms ). If families are purely paleo or purely neotropical, this is an indication that they probably only emerged after the separation of Africa and South America, i.e. at the earliest in the Upper Cretaceous . Pantropical plant genera are relatively rare compared to families; these include begonias and passion flowers, as well as the genus Gnetum from the naked group .
