(Vereeniging tot instandhouding van het Oud-Studentenfonds te Utrecht) 

 and from the "Provincial Utrecht Society of Art and Science" (Provinciaal 

 Utrechtsch Genootschap voor kunsten en Wetenschap). 



The author wishes to express his indebtedness to all these persons 

 and bodies. 



Most of all, however he has to thank Prof. F. A. F. C. Went, who 

 took the initiative for publishing the work in its present shape and who 

 moreover, as well by his personal advice, as by his influence with the 

 above-mentioned societies, promoted more than any one else the publication 

 of this Enumeration. 



The kindest assistance was given to the author by the Director of the 

 Royal Botanic Garden at Kew, Sir W. T. Thiselton Dyer, by the Director 

 of the Kgl. Botanisches Museum at Berlin, Geheimrat Prof. Dr. A. Engler 

 and by the Director of the Botanical Institute at Gottingen, Prof. Dr. A. 

 Peter, who all enabled him to use their herbaria. 



Prof. Dr. F. Niedenzu at Braunsberg, Dr. O. E. Schulz at Berlin and 

 Mr. T. A. Sprague at Kew were so kind as to determine respectively the 

 Malpighiaceae, the Erythroxylaceae and part of the Bignoniaceae for 

 the present writer who expresses his sincere thanks to these gentlemen. 



Finally he has to thank his betrothed. Miss E. Kamerling, for compiling 

 the index and his brother, Mr. R. J. C. Pulle, for his assistance in going 

 through the proofs. 



It must be understood that the author does not claim completeness for 

 this work. But he hopes that it will give some idea df the present state of 

 our knowledge of the Surinamian flora and that it may lead to further 

 attempts, as well in the mother country as in the colony itself, of increasing 

 our knowledge of the botany of this interesting part of tropical South 

 America.
