A large portion of the Suringar collection has been deter- 

 mined hy Prof. I. Urban and many plants from it are mentioned 

 in his Symbolae Antillanae. 



Collection Aschenberg. 



In the herbary of the Botanical Laboratory of het University 

 at Utrecht is a fairly large collection of plants, gathered in Curagao 

 by Aschenberg. I have not succeeded is obtaining nearer infor- 

 mation about it. It will be seen from the Systematical part of 

 this Flora that a great many of the species, found by Suringar 

 and myself, have also been collected by Aschenberg. 



Collection F. A. F. C. Went. 



A number of plants has been collected by Prof. Dr. F. A. F. 

 G. Went during his stay in Curagao in 1901. In the Systematical 

 list they are indicated by the name Went. 



Collection Miss A. Lens. 



In 1907 Miss Lens collected a number of plants in Curagao; 

 this small collection is conspicuous by its fine specimens, since 

 Miss Lens could take much time in drying them. They are chiefly 

 ruderal plants and mentioned in the list by the name Lens. 



Collection W. Versluys. 



In 1907 Mr. W. Versluys.^ Government Agriculturalist made 

 a collection of plants, indicated in the list as Versluys. It con- 

 tains especially grasses. 



Collection I. Boldingh. 



As in the introduction to this Flora an account is given of 

 my investigation of the Flora of the D. W. I. Islands, it may suffice 

 here to mention the places where I stayed and from where I 

 undertook expeditions. They are given in the same order as the 

 expeditions themselves ; for nearer information and for the meaning 

 of the abbreviations in the Systematical Part I refer to the expla- 

 natory notes of the maps.
