succulenta; also Machaonia Ottonis and Bursera occur there. 

 On the ground grows not much more than u fr\v Euphorbia 

 thymifolia and Phyllanthus polycladus. 



The lime table land on Hieronymusberg. 



This contains a similar vegetation, only somewhat poorer; here, 

 however, Guaiacum officinale and Guaiacum sanctum are conspicuous, 

 besides Phyllanthus Euwensii and Casearia bonairensis, Aculvj.hu 

 Poiretii and Pisonia bonairensis. 



Very divergent in its plant-growth by the presence of some forms 

 which are entirely lacking in other places is the 



Christoffelberg. 



At its base we find again the strongly developed Croton vegetation 

 of the lower hilly country, which besides Cactuses also contains 

 many Croton flavens, Jatropha gossypifolia, Acacia villosa, Haema- 

 toxylon Brasiletto, Cordia cylindrostachya, Jatropha urens, Acacia 

 tortuosa. Melochia tomentosa, Randia aculeata and Phyllanthus 

 Euwensii. Also the lower Sida species, Indigofera suffruticosa, 

 Convolvulaceae and Opuntia curassavica are found. Higher up this 

 vegetation remains, but more Coccoloba diversifolia, Myrtaceae 

 and Capparis linearis appear, while Bromelia lasiantha often covers 

 the ground. Of trees we now see Machaonia Ottonis and Tecoma 

 chrysantha, Pisonia fragrans, Bumelia obovata and Capparis 

 Breynia, while Haemataxylon Brasiletto becomes more prominent ; 

 also Maytenus Sieberiana, Fagara monophylla, Jacquinia barbasco, 

 Erythroxylon havanensis. At a height of about 200 metres Coc- 

 coloba diversifolia becomes the principal tree; we also notice the 

 Schomburgkia tibicinis and Trichilia trifolia, but still the impres- 

 sion is that of a luxurious Croton vegetation. Acacia tortuosa is 

 still frequent here and also Phyllanthus Euwensii, while Vit-'X 

 umbrosa and Clusia rosea give a peculiar aspect to the vegetation 

 on the higher parts. On the top Ficus Brittonii, Clusiu rosea, 

 Maytenus Sieberiana, Triplaris coriacea are frequent, among which 

 Tecoma chrysantha, Caesalpinia coriaria and many Lantanu cuinuru, 

 Cordia cylindrostachya and Gundlachia corymbosa. 

 So the higher parts especially have a rather different vegetation. 

 The mountainous complex Behoenda and surrounding parts do 

 not reach the same height but in their plant species show much 

 resemblance with the Christoffelberg. The only conspicuous plant 

 I noticed there was Caseariu bonain-iiHs: ln-si-les tin- bush is 

 somewhat higher and denser in Behoenda than on the lower parts 

 of Christoffelberg. 

 The poorest vegetation is found on the barer mm-cuK a hills,
