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 ,Carlsbergfondet* 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 1% 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 [ 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.
