Two-thirds of the strand-flora of the island of Krakatau are made 

 up of species which are ubiquitous on tropical coasts. Of the 67 

 species in the above list, 42 (indicated by f) are included as typical 

 strand-plants in the lists given by Schimper 1 and Hemsley 2 : 35 of 

 these are widely spread and abundant beyond the Malay Archipelago 

 and may occur over the whole tropical zone. The importance of 

 these plants in the strand-flora on the coast of the Sunda Strait 

 region is illustrated by an examination of the lists of the species 

 which we collected on Edam, at Vlakke Hoek (Sumatra) and Java's 

 First Point (pp. 1214, 17, 18, 24, 25). 



Of the 36 halophytes from Edam, indicated by f , 18 occur on the 

 Krakatau islands ; the islands possess 21 of these widely spread species 

 in common with the strand-flora of Vlakke Hoek and 14 with that of 

 Java's First Point. An equally well marked agreement is shown by 

 a comparison with other localities on the coasts of Java and Sumatra,
