INTRODUCTION. lv 
cold southern latitudes, though one species of Salix is a native of South Africa, and 
another species extends about as far south as the northern limit of Fagus in the Andes, 
and further south in eastern 8. America. 
Let us now briefly examine the composition of the very poor insular portion of the 
Antarctic Flora, excluding the Falkland, Campbell, and Auckland Islands. The islands 
or groups of islands more or less explored botanically are South Georgia, Marion 
(Prince Edward group), the Crozets, Kerguelen, Heard (Macdonald group), and 
Macquarie, lying between 38° W. and 160° E. longitude. 
The accompanying table demonstrates the existence of an antarctic phanerogamic 
element all round the southern hemisphere. It will be perceived that the only island 
possessing endemic plants is Kerguelen, and these may possibly yet be discovered in the 
Crozets or Prince Edward Island, just as Pringlea antiscorbutica has been. ‘Two genera,
