The following contribution to the flora of the island of Koh 
Chang has resulted from the examination of a number of collections 
of freshwater Chlorophycece made during the stay of the Danish 
Expedition in Siam in 1899—1900. The collections were preserved 
in weak alcohol or formaline and were twenty four in number. 
Very few filamentous Chlorophycee were obtained, the chief of 
which were four species of Gdogonium and four of Spirogyra, one 
species of each of these genera being quite new. Two of the col- 
lections from stagnant water in the jungle were rich in various 
free-swimming Palmellacee. Some four or five of the collections 
contained a number of Desmids, many of which have proved to 
be very interesting. 
The only papers dealing with freshwater Algee from this region 
of the world are: — Joshua on ,Burmese Desmids“ (1886);

Koh Chang.
