St. Martin. 



Widely different from the former two Islands the vegetation 

 of St. Martin is chiefly composed of a Crotonvegetation much more 

 developed than on St. Eustatius, whereas the tropical woods 

 that are to be found on St. Eustatius and Saba are not to be 

 met with on St. Martin. 



The greater part of the Island being cultivated the ruderal- 

 plants are dispersed in almost the whole Island, along the roads 

 and on the plantations and meadows, except in the typical Croton- 

 vegetation which on the outer parts of St. Martin is gradually 

 changing into a vfell developed Littoralflora. 

 This Littoralflora together with the Crotonvegetation commands 

 the whole aspect of St. Martin. 



Only where the hills are a little higher the Eriodendronvege- 

 tation like that one of the northern part of St. Eustatius is to be 

 found. 



The vegetation in the neighbourhood of the Saltponds with 

 species that are not to be seen on the other Islands has also a 

 typical aspect. 



According to the results I got in studying the vegetation of St. 

 Martin more minutely I dare say that we can also trace out here 

 the following formations.
