PREFACE. 



In. continuation of his voyage to the Dutch "West Indian Islands 

 St. Eustatius, Saba and St. Martin, about which particulars are 

 to be found in the first part of the Flora of the West Indian 

 Islands!), the author undertook a second voyage in 1909—1910 

 in order to study the flora of the Islands Curaqao, Aruba and 

 Bonaire. 



It was again on the suggestion of Dr. F. A. F. C. Went, Profes- 

 sor of Botany in Utrecht University, that this voyage was under- 

 taken and it is principally owing to his exertions that the fol- 

 lowing corporations gave finantial support: de Maatschappij ter 

 bevordering van het Natuurkundig onderzoek der Nederlandsche 

 kolonien (Society for promoting the Physical investigation of the 

 Dutch colonies), de Koninklijke Academie van Wetenschappen te 

 Amsterdam (Royal Society at Amsterdam) which put the P. W. 

 Korthals fund at my disposal, the Committee for the F. W. van 

 Eeden fund, het Koninklijk Nederlandsch Aardrijkskundig Genoot- 

 schap (Royal Dutch Geographical Society), het Nederlandsch 

 Natuur- en Geneeskundig Congres (the Dutch Physical and Medical 

 Congress) and het Provinciaal Utrechtsch Genootschap van Kun- 

 sten en Wetenschappen (Provincial Utrecht Society of Arts and 

 Sciences); also the Botanical laboratory contributed towards the 

 expense of transporting the plant collections in exchange for 

 which it received the collections. To all these corporations I wish 

 to express here my sincere thanks. Het Provinciaal Utrechtsch 

 Genootschap van Kunsten en Wetenschappen again subsidized in" 

 order to have this flora printed. 



Besides to the corporations mentioned the author is greatly 

 indebted to Prof. Dr. F. A. F. C. Went and to his Excellency 

 the Colonial Minister for his recommendation to the Governor of 

 Curagao.
