On the request of the Botanical Museum of Copenhagen Mr, E. Lind- 

 hard, charged by the Danish East-Asiatic Company with timber-felling 

 in the Raheng District, Upper Siani, has brought together a small collec- 

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

 known with regard to the flora of Upper Siam, a list of these plants 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 other hand 

 they give some idea of the herbaceous vegetation 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 vegetation of these sunny and rather dry places in the winter 

 months (December- January); in the summer the herbaceous vegetation 

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

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

 single species (Oltelia japonica) is a water-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 collector,
