is mounted and these ciphers the jilant is sufficiently indicated, I 

 thought it better not to give tlie long numbers that are used in 

 „'sRijiis Herbarium". 



The plants collected in the different Islands are thus given : col- 

 lection Boldingh, collection Suringar, both in the order of the day 

 of collecting, collections A^an Grol-Meyers and collection Lionarons. 

 Not all the vernacular names people told me are given here, but 

 the names I have given in this Flora are used without any doubt. 

 The heights where the plants were collected are given with the 

 greatest accuracy possible. 



Whenever a plant struck my attention although I did not think 

 it necessary to collect it, I made some notes about it ; these notes 

 arc also to be found in this Flora, printed with small type. 



As to the flowering and fruiting time of the plants I did not 

 think it necessary to mention with every plant whether I col- 

 lected flowers on fruits as the greater part of the plants are 

 collected with flowers, either by Suringar, Van Grol-Meyers or 

 by myself. 



I wish to draw the attention to the fact that I have tried to 

 render this Flora of the Dutch West Indian Islands as complete 

 as possible, both by what my own investigations have taught me 

 and what I could find elsewhere. 



Only the genus Melocactus has not been studied with the same 

 care, as I was sure I could not add anything to the work done 

 by Suringar on this head by the data I could bring together with 

 out giving too much time to it. So I refer to the studies of 

 F. W. R. Suringar on Melocactus and those of J. Valckenier 

 Suringar.
