X Preface. 



an extensive correspondence on forms that were diflacult to deter- 

 mine. Thanks to his communications and assistance with the 

 determinations a number of plants have now been named with 

 greater certainty, than would have been possible without his 

 valuable help which was especially necessary with the Cactaceae. 



This Flora is divided in Three Parts; whereas the different Parts, 

 Sections and Chapters need no further explanation, a short account 

 of the methods I followed in nomenclature, synonymy and distri- 

 bution of plants is given here. 



The enumeration of Families and Genera ,is very nearly given 

 after the order of De Dalle Torre et Harms: Genera siphonoga- 

 marura ad systema Englerianum Conscripta (1908). 

 In a few cases I thougt it better to follow: 

 Urban : Symbolae Antillanae and Urban : Additamenta ad Cog- 

 nitionem Florae Indiae Occidentalis 1892—97. 

 The names of the species used are mostly drawn from these two 

 papers and Engler und Prantl. : Die naturlichen Pflanzenfamllien 

 up to 1914, Engler: Regnum Vegetabile up to 1914, or from other 

 monographs. 



Whenever I could not find any name in the above mentioned 

 publications I took the name I thought best after the Internatio- 

 nal rules for Botanical Nomenclature chiefly of Vascular Plants. 

 Wien 1905. (Verb. Int. Bot. Congr. 1805 Wien.). 

 Besides the names thus given I also mention the synonyms that 

 are used in: Grisebach: Flora of the British West Indian Islands, 

 and in a very few cases still another one. 



I tried to arrive at the greatest completeness possible in giving 

 the data about the names thus used, and I also mentioned the 

 pages where the plants occur in : Grisebach : Flora of the British 

 West Indian Islands. 



To every plant is added the name of the Dutch West Indian 

 Windward Island where it is found in this order : Curagao, Aruba, 

 Bonaire. 



I have mentioned as much as I could find about the distribution 

 of the plants in all parts of the world, and these data are taken 

 from the following publications in this order: 

 Urban: Symbolae Antillanae, and Additamenta ad Cdgnitionem
