On Jan. 18 I departed to Curasao, from where I left for Bonaire 

 on Jan. 28. There I was from Jan. 30 to Febr. 14 the guest of 

 Pastor P. A. Euwens at Rincon. I further mention here Mr. P. 

 van Teeckelenburg who put his house at my disposal for the 

 remainder of the time I spent on Bonaire. 



On Febr. 20 I went to Curasao and returned to Holland on Febr. 27.

 Haseth Moller, F. J. C. Beaujon, J. L. J. 0. Cadieres, de Wind, 

 A. Hermus, H. J. Cohen Henriquez, Th. van Sadelhoff and P. A. 

 Euwens. Mr. Duyfjes gave me much informations about the geology 

 of the islands. 



In the elaboration of the collected plants I was helped by Prof. 



I. Urban who gave a number of indications for forms not directly

E. Schulz named a number of the Malpighiaceae, Sapindaceae and 



Solanaceae. Dr. H. Hallier determined by far the greater part of 



the Convolvulaceae. Prof. W. Trelease determined the Agave 



species and Dr. A. S. Hitchcock some Gramineae. 



To the Director of the State Herbarium at Leyden I am indebted 



for the loan of the plants of the Suringar collection.

collected by himself in Curasao to work out and with whom I had
