* The percentage of Filices is calculated from the whole number of vascular species =12233. 

 f This is probably far from the true position of this order, as very si ghtly different forms have been assigned 

 the rank of species in the latest monograph. 



% Leaves of a plant, probably a Begonia, have been collected in North-western Australia.
