85. The Region of Chatham Island. Situated far to the Eastward 

 of New Zealand. 



86. The Region of Auckland Island. Of limited area; but a dis- 

 tinct forest region, situated to the southward of New Zealand. 



87. The Forest Region of New Zealand proper. The tract of 

 forest much interrupted ; but the openings all fern-covered, except 

 where the ground is marshy. 



88. The Kermandec or Sunday Islets. Situated to the North- 

 east of New Zealand, and possibly presenting a trace of a distinct 

 botanical region. 



89. The Region of Norfolk Island. Situated to the Northwest 

 of New Zealand ; of limited area, but known to contain several pecu- 

 liar species of plants. 



VIII. The Australian Adaptation. 



The plants not exposed to severe cold ; the climate continental and 

 uniform ; but in the absence of seasons, the rains infrequent and 

 irregular, both as to time and quantity. As many as five botanical 

 regions can be distinguished. Colored brown in the accompanying 

 map. 



Two of these regions are Tropical, and should perhaps be regarded as 

 East Indian regions ; but according to the descriptions of visitors, the 

 Australian character dominates throughout in the vegetable growth. 



90. The Region of Northeast Australia. A Tropical region. 



91. The Region of Northwest Australia. A Tropical region ; con- 

 tinuous with the preceding, but the climate described as more arid. 



92. The Region of Southeast Australia. South of the botani- 

 cal Tropic, which may be placed provisionally in the twenty-fourth 

 parallel of S. latitude. 



93. The Tasmannian Region. Including Tasmannia or the large 

 island formerly called " Van Diemen's Land," and probably, the ex- 

 treme Southern portion of Australia. 



94. The Region of Southwest Australia. Perhaps confined to 

 the extreme Southwestern portion of the continent. The intervening 

 Interior space seeming {sufficiently extensive for a sixth botanical 

 region.
