On the calcareous soil near Bolivia we find a still denser 

 Croton vegetation. The ground is there in some places densely 

 covered with Spermacoce tenuior, Pectis, Pappophorum, Sida, 

 Aristida Swartziana, Croton ovalifolius, the higher shrubs being 

 mostly Jacquinia barbasco, Bursera simaruba, Randia aculeata, 

 Malpighia, Bursera tomentosa, Cordia cylindrostachya, Capparis 

 jamaicensis, Caesalpinia coriaria, Haematoxylon Brasiletto. On the 

 ground we find many Panicum lachnanthum, Krameria ixina, 

 Eragrostis ciliaris. In other places Rhacoraa crossopetalum and 

 Coccoloba diversifolia are the principal shrubs, between which 

 Pisonia bonairensis, Bumelia obovata, Guaiacum sanctum, Beureria 

 succulenta, Metopium Brownei, Casearia bonairensis and a few 

 Tecoma chrysantha as trees. Among the lower plants we notice 

 Euphorbia thymifolia, Morinda Royoc, Mariscus fuligineus, Corchorus 

 tomentosus. On the Northern slopes of these lime terraces Clusia 

 rosea is very conspicuous. 



As an example of the vegetation on the higher lime table-lands 

 I choose: 



The lime table- land near Montagna. 

 Here a dense and high forest of shrubs is found, parts of which 

 remind us of a thick wood. Sometimes we meet Randia bushes 

 without any underwood ; besides we have here many Bursera 

 bonairensis, Bursera simaruba and Bursera tomentosa, Casearia 

 bonairensis, Bumelia obovata, Capparis jamaicensis, Machaonia 

 Ottonis, while Lantana camara and Croton flavens together with 

 Rhacoma crossopetalum form the underwood or the chief con- 

 stituent in most places. Also Euphorbia cotinifolia grows here, 

 while of the Cactaceae especially Cephalocereus lanuginosus is 

 conspicuous. On the ground we have Corchorus hirsutus, Sida, 

 Eragrostis ciliaris, Aristida Swartziana, Elytraria squamosa, while 

 Mariscus fuligineus and Ernodia litoralis are also found here. 

 As a higher hill not consisting of lime, we mention 



The Joewa hills and surroundings. 

 We reach these through high dense bushes of shrubs of Randia 

 aculeata and Machaonia Ottonis, between which hardly any other 

 trees or shrubs occur. On the ground are Spermacoce tenuior, Ely- 

 traria squamosa, Physalis, Opuntia curassavica. -On other spots we 

 find more Capparis jamaicensis, Capparis cynophallophora, Prosopis 

 juliflora, between which many Cephalocereus lanuginosus, Haemato- 

 xylon Brasiletto. We further find again whole complexes of Croton 

 flavens between which Casearia bonairensis, Lantana camara, 

 Maytenus Versluysii, Cordia alba, after which we come again
