VI Preface. 



Flora of the Dutch West Indies, has helped me so energetically 

 by his personal advice as well as by his influence with the above 

 mentioned Societies. 



I am glad to have an opportunity now to express my thanks to 

 all those who have helped me in any way in promoting my studies. 

 As to the Dutch Antilles I thankfully mention the Governor of 

 Curagao Jhr. J. 0. de Jong van Beek en Donk and the admini- 

 strators of St. Eustatius, G. J. van Grol, and T. G. Groebe, the ad- 

 ministrator of Saba H. J. Beaujon, the administrator of St. Martin 

 A. J. 'C. Brouwer and the maire of the French Part of St. Martin 

 D. Beauperthuy. 



Moreover: in St. Eustatius: Mrs. J. van Grol-Meyers, Mr. J. Morgan 

 Griffith, Rev. P. Delgueur, Mr. J. G. C. Every, Messr. Hill and 

 Mr. Hassel; in Saba: Dr. A. C. W. Lionarons, Rev. Mulder and 

 Mr. T. Holms; in St. Martin: Mr. J. A. Gravestein, Mr. L. A. van 

 Romond, Mr. A. A. van Romondt, Mr. D. J. van Romondt, Mr. 

 W. E. van Romondt, Mr. W. Netherwood and Mr. F. Morales. 

 During my voyage to the West Indies I experienced much friendly 

 help from Sir Daniel Morris, Mr. J. R. Bo veil, R. P. Duss, Mr. 

 Stephens and Mr. Shepherd. 



I also highly appreciate the assistance I got in Holland where 

 I was informed with the greatest loyality by Mr. L. A. Bakhuis, 

 Dr. J. Boeke, Dr. M. Greshoff, Dr. G. A. F. Molengraaff, Dr. J. 

 Yalckenier Suringar and Dr. C. E. A. Wichmann. 

 According to the wishes of the „Commissie van het F. W. van 

 Eedenfonds" I paid much attention to the cultivated plants too; 

 in a former publication: Lijst van Planten die door de bewoners 

 van de drie Nederlandsche Antillen, St. Eustatius, Saba en St. 

 Martin als geneeskrachtig worden beschouwd (Bull. Kolon. Mus. 

 Haarlem n. 38 (2907) p. 93—112), I wrote on the use made of 

 certain plants and in this Flora now I have enumerated all the 

 cultivated plants I met with and which I was able to determine. 

 I also feel very much indebted to the following Directors of 

 ,,'sRijks Herbarium" at Leiden viz: Dr. -J. M. Janse, Dr. J. P. 

 Lotsy and Dr. J. W. C. Goethart, who greatly facilitaLed by their 

 kind assistance my working there on the collection of Dr. F. W. 

 R. Suringar. 



But most of all I kindly thank Prof. I Urban for his assistance 

 when I was working in the magnificent Herbarium Krug et 

 Urban in the Konigl, Bot. Garten und Museum Steglitz-Dahlem 

 (Berlin.). 

 Although the time I could be there was only very short, my visit
