The preceding tables are characteristic of the groups within the Ant- 
arctic Element. They show affinities between the three great southern land 
masses, with Madagascar, New Caledonia, and New Zealand as intermediate 
j^oints. It is interesting to find that, in general, the links between Australia 
and South America are usually stronger than those between Australia and 
South Africa. These will be referred to again under the Australian Element. 
Amongst the Restionaceae there is a high degree of endemism both in the 
Australian and South African groups, with one conjunctive genus for America 
and one for South Africa. The Centrolepidaceae are more strictly Antarctic, 
and the link here is between South America and Australia. The same holds 
good for the Epacridaceae and Stylidiaceae, whieli are not represented in 
South Africa, the former without conjunctive genera, the latter with two. 
Amongst the Proteaceae however, there are powerful links with South America, 
in the Orevilloideae, with two conjunctive genera ; while amongst the Proteeae
