On the request of the Bolanical Museum of Copenhagen Mr. E. Lind- 

 hard, chargea" by ihe Danish East-Asiatic Company with timber-felling 

 in the Raheng District, Upper Siam, lias brought together a small collec- 

 tion of plants preserved in Schweinfurth's manner. As very little is 

 known with regard Lo the flora of Upper Siam, a lisl of these planls may 

 be of some interest; the number of species is only 100 and it is evident 

 that so few species do not at all represent the flora. On the olher hand 

 they give some idea of the herbaceous végétation of the country; the list 

 will show that nearly all the enumerated species are herbs. The whole 

 collection has been made in open places in the woods and in river- 

 banks, and we do not fail that the many grasses and herbs form 

 the main végétation of these sunny and rather dry places in the winler 

 monlhs (December-January); in the summer the herbaceous végétation 

 is faded away. — A few species, e. g. the ferns and the Hoya's, have been 

 collected in more rieh localities (shaddy woods along the rivers), and a 

 single species (Ottelia japonica) is a wa ter-plant. 



No species of tree nor of shrub has been collected, so the list does not 

 give any information of the composition of the forest. The colleclor,
