Rivers and Oases
The larger rivers serve to spread the vegetation of the Mediterranean zone q.v. further south and allow the introduction of the plants of Africa to the north. Both rivers and oases support many anthropogenic species resembling in extreme cases tropical botanic gardens.
The zones were established by the International Phytogeographic Excursion of 1936.

Famous quotes containing the word rivers:
“Melancholy is at the bottom of everything, just as at the end of all rivers is the sea. Can it be otherwise in a world where nothing lasts, where all that we have loved or shall love must die? Is death, then, the secret of life? The gloom of an eternal mourning enwraps, more or less closely, every serious and thoughtful soul, as night enwraps the universe.”
—Henri-Frédéric Amiel (1821–1881)
