Aruba. 



As respresentative for the vegetation of the lower calcareous parts 

 of Aruba I choose 



The country near Manshebo. 



The coral-lime soil is very bare here and scantily overgrown. 

 Melocacti and Cereus griseus prevail with Aristida Swartziana, 

 Euphorbia thymifolia, Opuntia and fairly numerous Jatropha gossy- 

 pifolia; an occasional Prosopis juliflora is somewhat higher than 

 the other plants. Jatropha urens is frequent here. Of the grasses 

 Cenchrus echinatus, Eragrostis Urbaniana, Anthephora hermaphro- 

 ditica, Paspalum glabrum and Bouteloua Humboldtiana are noticed ; 

 besides Lithophila muscoides, fleliotropium curassavicum, Sesuvium 

 portulacastum, Capraria biflora and Scoparia annua as lower herbs. 

 As shrubs or trees we have widely scattered Conocarpus erecta, 

 Suriana maritima, Erithalis fruticosa, Bumelia obovata, Coccoloba 

 uvifera and Beureria succulenta which nowhere form a dense mass. 

 On the low dune forjnations Tournefortia gnaphalodes abounds. 

 As an example of a more elevated lime district we mention: 



The calcareous table-land near Fontein. 

 Here the soil is very bare in some places or covered with a fairly 

 dense mass of shrubs ofLatanacamaraand Cordia cylindrostachya; 

 Prosopis juliflora is abundant and Aristida Swartziana covers the 

 ground ; whole fields are densely overgrown with Antirrhoea acutata. 

 Above these shrubs Jacquinia barbasco and often whole complexes 

 of Peltophorum Suringarii rise somewhat higher, while this dense 

 mass of shrubs is further formed by Beureria succulentia, Capparis, 

 Crescentia Cujete, Guaiacum officinale, Bursera simaruba, Bumelia 

 obovata and Cordia alba. 



On spots where the vegetation is less high see besides Opuntia 

 many Pilocarpus racemosus and Croton flavens, other complexes 

 being formed by Phyllanthus Euwensii and Casearia bonairensis. 

 On the higher part, especially near Seroe Kadoesji we also find 

 Croton niveus, Tecoma chrysantha, Bumelia obovata, Cordia alba, 

 Jacquinia barbasco and Beureria succulenta, which form a true 

 forest there. Also Melocacti occur everywhere. As an example of 

 a somewhat different vegetation on chalk table -lands we mention: 



The calcareous table -lands near Belashi. 

 Here again we find a more or less rich Croton vegetation. In the 

 bare parts the vegetation on the ground consists of Dactyloctenium 

 aegyptium. Euphorbia thymifolia, Eragrostis ciliaris, Torulinium
