One excursion was macle tu the eastern rfloiies of Mount 

 Salak the tlora of which was thoroughly investigated. The ascen- 

 sion of the mountain from this side ofîers no serions difficulties. 

 Some remarkable plants were collected, among which Dipl 3^00- 

 sia p il osa Bl., a new species of Panicum and Sarcopyra- 

 m i s j a V a n i c a. 



The last excursion was made to Mount Hijang which could 

 be easily ascended from the north-east side. Dr. Jeswiet and 

 Dr. Bremekamp, to whom I am very much indebted, had the 

 kindness to accompany me and to make, of theii- own free will, 

 a présent to our Herbarium of ail the plants they found. The 

 large undulating plains which are found at an altitude of 2100 — 

 2200 M above sea-level and which are commonly called aloon- 

 aloon are covered with a dense végétation of grasses, the greater 

 part of which had but recently been destroyed by tire. Notwith 

 standing this destruction many interesting species could be col- 

 lected. The commonest grass of the aloon-aloon is Pennisetum 

 compressum, which has sometimes been confounded with 

 Festuca nubigena, which it resembles in habit. It is inter- 

 mixed with Sporobolus diander and Imper ata. The com- 

 monest fern by far is Pteridium aquilinum which grows 

 everywhere on those plains and fructifies abundantly. Ranun- 

 cuUis j avanie us which was already mentioned by Junghuhn, 

 is very common. We had the pleasure of finding many spéci- 

 mens of Primula imperialis at an altitude of 2600-2700 

 M. Many othei- interesting plants were collected among which 

 Clethra canescens, which was discovered about 65 years 

 ago by Zollinger and is very common in some forests on 

 Mount Hijang at an altitude of 2100-2400 M. 



The investigations will be carried on for about one year and 

 a half more. At the end of that period the botanical results will 

 be laid down in a work on the floraofJava. When the latter is 

 completed it will be possible to find the name and the area of 

 a plant without serions difficulties. The want of such a work 

 is keenlv felt.
