hope this list will be of some interest, although it cannot claim to 

 be complete as it is only the results of my collections during my 

 stay in the island in three winter-months. 



These contributions to which the present is an introduction 

 only will deal with the systematic relations of the concerning 

 plants and their geographic distribution. As I intend to publish 

 later on a more detailed description of the vegetation of Koh 

 Chang from a biological and ecological point of view where 

 particulars will be given about the general climatic and geographic 

 facts, I here confine myself to the most necessary informations. 



The expenses of the Expedition were paid by the Danish 

 Government and the „ G ar Is bergfondet " and we undertook 

 our voyage under the auspices and with the sanction of the Bota- 

 nical and Zoological Museums of the University of Copenhagen 

 both of which contributed to our outfit and supplied the funds on 

 which we travelled. 



On October I s * 1899 we started from Copenhagen onboard 

 the Danish steamer „Siam" bound for China. During the sea- 

 voyages out- and homeward the time was occupied by collecting 

 and studying the zoo- and phytoplankton of the seas, we 

 passed through. After a short stay in Singapore, Bangkok was 

 reached in the middle of December. About a week later we left 

 that city onboard H. S. M. „Chamroen" for our destination, the 

 inner part of the east-coast of the Gulf of Siam. By the kindness 

 of the Royal Siamese Government and our excellent coun- 

 tryman Admiral A. de Richelieu some very valuable support 

 was granted us from the Siamese Navy. Thus we got residence 

 on the Naval Stations at Lem Dan (Koh Chang) and Lem 

 Ngob (Siamese mainland), and also men to assist us during our 

 dredgings or inland trips. Until the end of March I lived at 

 Lem Dan and spent the time collecting plants and studying the 

 flora of Koh Chang, for which purpose I undertook numerous 

 excursions by land to the hills or visited by boat the different 

 coasts of the island.
