Not less than 36 of the plants (indicated in the list by f) ai'e 

 included in Schimper's list 1 of the Indo-Malayan strand-flora as 

 typical halophytes, and 19 additional species (distinguished by *) 

 belong to genera which include characteristic strand species. In the 

 case of the majority of these plants there is no doubt that the seeds 

 and fruits are easily distributed by ocean-currents. A smaller number, 

 in view of the comparatively short distance between Edam and Java, 

 probably owe their introduction also to wind-agency. These are: 

 Eclipta alba, Wedelia glabrata, Cyperus hyalinus, Fimbristylis 

 spathacea, Polypodium quercifolium, or possibly introduced by 

 birds : Scaevola Koenigii, Morinda citri folia, Clerodendron inerme, 

 Premna foetida, Vitex Negundo, Allophyllus Cobbe, C assy tha fili- 

 formis. 



In addition to the numerous representatives of the Indo-Malayan 

 strand -flora, a large number of inland plants have become established
