spec., Artocarpus elastica Reinw. A thick-stemmed liana, a species 
of Gnetum and several varieties of Vitis climbed high up into 
the trees, whilst different kinds of Piper covered the trunks iu 
places. On the border were especially to be found large quan- 
tities of Bauhinia glauca Mall. Along the dry rice-field the forest 
had sprung up anew; here there was accordingly more under- 
growth and a new Vitex species, V. sebesiae H. J. L. was found, 
described by Dr Lam’). | 
April 29th, On this last day another excursion was started at 
the head of the Mangrove bay and continued as far as the first 
slopes up to about 100 Meter. The first part of the way traversed 
the areas already described, but where the hills began the 
character of the grounds began to get different again. Still the 
forest again conformed to the type discussed in the account of 
the excursion on the second day. At first we came across small 
spaces set-with Saccharum spontaneum L. and especially Impe- 
rata cylindrica P. B., such grounds as still form a large pro- 
portion of Krakatau and Verlaten Eiland. In these wilds there 
had developed certain herbs which we had not as yet come 
across, for instance Sida acuta Burm. and Sida rhombifolia L.; 
likewise a few species of trees: Mallotus ricinoides M. A. and 
Ficus leucantatoma Poir. were found here in quantities. 
_ From these day-by-day descriptions largely sketched on the 
spot, it should be possible to form an idea and picture of the 
vegetation occurring on Sebesy, though it always remains a 
difficult thing to visualise a flora to persons who have not ac- 
tually seen it. A few more pages may now be devoted to a 
discussion of general results and to drawing a parallel with 
what was noted on the various Krakatau expeditions. 
On Sebesy-island plants and galls were collected by me during 7 
days. The galls have already been described in an other article’)
