Saba. 



The Island of Saba makes a very different impression as St. 

 Eustatius does, especially by the total absence of a level country 

 like the Cultuurvlakte on the latter Island. 

 Owing to the conical form of Saba there are only steep slopes 

 of hills and these hills are covered by the same vegetation as 

 those in St. Eustatius, viz.: the Eriodendron vegetation. Moreover 

 there is a good quantity of almost naked rock where a very 

 poor flora is to be found. 



According to the fact that almost in all the localities that 

 are apt for cultivation the soil is occupied by the inhabitants, 

 there is a well developed vegetation of the cultivated region inter- 

 mixed with the Eriodendron vegetation. 



The Croton vegetation is only to be seen in a very few localities 

 and nowhere on Saba it is so predominant as in St. Eustatius. 

 That part of the Mountain higher than 500 m. above the sea- 

 level, though also greatly influenced by ruderal plants has a 

 very well developed tropical rainforest which, without losing 

 the typical character of the St. Eustatius forests is characterised 

 by its great number of Ferntrees. 



The vegetation of the seashore is very poor and has no influence 

 on the general aspect of the Sabavegetation. 

 Whereas it is not so easy to make a sharp difference between the 

 four Plantformations still I think it better also to trace out here 

 the four following typical groups: 



1. Vegetation of the Mountain top and the greater part of 

 all the slopes of the Island. 



2. Vegetation of some arid hills. 



3. Vegetation of the seashore and rocky localities. 



4. Vegetation of the cultivated region. 



Referring to page 267 we might take take the same series 

 of names I gave there for the first three divisons whereas the
