The majority of the species which have found their way to the 

 island during the last ten years belong to the phanerogamous plants, 

 which now give the characteristic facies not only to the strand 

 vegetation but to that on the plains and mountain slopes. While 

 the ferns have not materially increased in number, the total number 

 of phanerogams (15 species in 1886) has risen from 56 x in the 

 year 1897 to 92 in April 1906. The additional species are almost 

 equally distributed between the strand and inland flora. 



The following species belong exclusively or mainly to the strand- 

 zone of Krakatau and Verlaten island :

 obtained in 1897 the two species of Conyza and Senccio sp. found by Treub.
