§ 8. 

 On the Tasmanian Flora. 



For an account of the physical features of Tasmania, in so far as they affect the vegetation, I 

 must refer to Strzelecki's excellent ' Physical Description of New South Wales and Van Diemen's 

 Land,' where the relations of the fores;: to the soil and elevation, and of all these features in Tas- 

 mania to those of south-eastern Australia, are well portrayed. 



The primary feature of the Tasmanian Flora is its identity in all its main characters with the 

 Victorian, aud especially of the mountainous parts of that colony ; it differs only in having fewer 

 orders, genera, species, more Antarctic and New Zealand elements, and fewer tropical, all of which 

 might be expected from its geographical position and its climate, which is much more equable and 

 humid than any district of Australia. There is, indeed, one part of Victoria, viz. Wilson's promon- 

 tory, of which the vegetation is described as peculiarly Tasmanian, and a glance at the map shows 

 that here again geographical proximity and uniformity of vegetation go together. There are besides 

 a veiy few south-western Australian types in Tasmania, that have not also been found in the eastern 

 Australian continent. 



Before proceeding with the analysis of the Tasmanian Flora, I shall give a list of the species, 

 with the distribution of each, and indicate the Floras of which each genus may be considered most 

 strongly representative. These are : — 1. The Australian continent; 2. New Zealand and Polynesia; 

 3. The Antarctic Islands; 4. South American ; 5. Europe (including North America, North Asia, and 

 North India, in so far as these share European features). Many species may be classed under two or 

 more of these divisions, as Anemone, which is absent in Australia and New Zealand, but is Antarctic, 

 American, and European. I have also put an asterisk to every species considered by Mueller, Archer 

 or myself as probably a variety, and noted which are subalpine aud alpine. Mr. Archer has further 

 revised the list, and added " Ch." to every species found within fifteen miles of Cheshunt.
