266 Phytogeographical. 



When taking the vegetation in general and without entering into 

 details we may consider it to be identical on the three Islands. 

 From the short notes however I give in this chapter on the as- 

 pect of the different Islands it will be obvious that on each of 

 the three Islands a particular Formation gives a predominant cha- 

 racter to each of them. 



St. Eustatius. 



The monotony of the level part of St. Eustatius is relieved 

 by some plantations surrounded by trees and by roads also bor- 

 dered by trees and shrubs. 



The formation that predominates in the „Cultuurvlakte" is a 

 dry shrubby vegetation of a greyish aspect that I will call the 

 Croton vegetation, following the nomenclature of Eggers in his 

 Flora of St. Croix and the Virgin Islands. 



The greater part of the hills near Signalhill and Concordia are 

 also covered with the same vegetation. 



Only the higher parts of these hills as well as the Quill are 

 covered with a greenish wood that I will call the Eriodendron 

 vegetation also in analogy with Eggers 1. c. 



These two parts of the vegetation ai-e not wholly sepai'ated 

 and both of them are intermixed with those plants which form 

 the vegetation of the cultivated region. 



The impracticable parts of the rocky cliffs covered only with 

 few plants form a typical vegetation with thicker or more coria- 

 ceous leaves in close relation with the vegetation of the seashore ; 

 the latter is not very well developed in St. Eustatius as there is 

 but a small beach and the Cultuurvlakte is about 40 m. above 

 the sealevel. 



Without entering into details we can [H'actically divide the ve- 

 getation of St. Eustatius in : 



1. Vegetation of the higher parts of the mountains. 



2. Vegetation of the Cultuurvlakte and the lower parts of 

 the mountains. 



3. Vegetation of the seashore and the rocky localities of the 

 Island. 



4. Vegetation of the cultivated region. 



Whereas a survey of the vegetation of St. Eustatius based 

 on these principles is given in the following lists it may be men- 

 tioned here that an almost synomical list could be given, viz:
