NOTES ON THE PHYTOGEOGRAPHY AND FLORA OF THE MOUNTAIN SUMMIT PLATEAUX OF TASMANIA.

The article discusses the phytogeography of the state of Tasmania. Tasmania is a small island about 27,000 square miles in the South East of the Australian continent. The northern coast is about 184 miles from that of Victoria and an elevation of only 180 feet would suffice for broad bridges on which one could pass dryfoot from Tasmania to the Australian mainland. The north and north- east portion of the island is less protected from the prevailing west winds of the Antarctic region by the West Coast mountains and the Central Plateau resulting in a lesser rainfall. The highest altitude in Tasmania is limited to 5000 restricted to a few masses of rock, vestiges of a former uniformly level area. There are no glaciers or permanent snow, therefore alpine conditions do not prevail.
