On some results of the botanical investiga- 

 tion of Java (1911 1913) 



Many data required for the writing of a good tlora of Java 

 are as yet déficient. Very many species hâve been collected in 

 a single or in a fevv localities only, or are represented by bad 

 spécimens so that it is quite impossible to give a good des- 

 cription of them and to trace the area they occupy. Keenly I 

 felt this want when preparing the first volume of my School- 

 ilora for the press. Immediately after the completion of this first 

 volume I thought it my duty to point out to Government the 

 necessity of completing our Herbarium. In conséquence of our 

 request the funds necessary for a botanical investigation of Java 

 were raost liberally granted. 



Though those investigations are still very far from their end^ 

 it is désirable to give a record of what has been done until 

 now. 1) Many localities hâve been visited and the tloi-a of ail 

 those localities was collected as complète as was possible. 

 Until now about 10000 spécimens hâve been gathered. Each spéci- 

 men was provided with a label, on which were written the latin 

 and c.q. the indigenous names of the species, the name of the 

 habitat and particulars about the latter, iiot forgetting the altitude 

 above sea-level. Wherever it was necessary and feasible, parti- 

 culars about the spécimen itself were added. Ail collected spé- 

 cimens were or ai'e to be inserted into the Herbarium Générale 

 at Buitenzorg. 



Until now 20 great excursions and several lesser ones hâve 

 been made. A list of the new and rarer plants fourni ou those 

 excursions is given at the end of this bulletin. The list is by no 

 means a complète one because many of the spécimens could not 

 yet be determined with certainty. 



Two of the travels were made in Ban ta m. They had very 



1). From some outsiders also we hâve received most valuable contributions to 

 our Herbarium Générale among wiiidi those uf Dr Docters van Leeuwen, Mr Lorzingen 

 Mr Mousset were very rich. The m-iny important plants found by them are not 

 mentioned hère.
