Two paragraphs from Cheesman (1909) might be quoted: 



Of 27 species of flowering plants and ferns known from the Kerguelen-South 

 Georgia region, 20 are found also in the subantarctic islands of New Zealand 

 while 27 are found in Fuegia and the Falkland Islands. The total number of 

 Fuegian plants found in the subantarctic islands of New Zealand is 29, 14 of 

 these extending also to the Kerguelen and South Georgia groups of islands. 

 These figures deal only with the specific identity; if we consider the genera, 

 we find that, out of 88 genera found in the subantarctic islands of New Zealand, 

 there are no less than 56 with representatives in Fuegia. 



Eleven species of plants found in the subantarctic islands of New Zealand 

 are found either in the Tristan da Cunha group in the South Atlantic or in the 

 Amsterdam Island group in the Indian Ocean, the flora of these two groups 

 possessing many points of agreement notwithstanding their wide separation and 

 showing also undoubted traces of affinity with those of Fuegia and Kerguelen. 

 Two of these 11 species, however, do not occur in Fuegia or the Kerguelen-South 

 Georgia group of islands. 



What parasites, if any, can best be studied to test and extend the 

 significance of the distribution of these and other southern hemisphere 

 plants? Will they be some group or groups of fungi? Will predatory
