and a big Cyperacea, Fuirena umbellata Rottb., in a waste of 
weeds like Wedelia biflora DC. and Pouzolzia zeylanica Benn., 
overgrown with Vitis trifolia L.; also Tournefortia tetrandra BI. 
was represented here. The sunny open glade swarmed with all 
sorts of insects especially butterflies. The Vitis which in the 
_ marsh itself lay over the herbs, climbed high up into the trees 
in the surrounding forest, combined with Trichosanthes tricus- 
pidata Lam. This margin also produced Costus speciosus Bl. 
In the afternoon the motor launch conveyed me to Huis- 
mans-Kiland, an islet situated just in front of the land-point. 
One can walk round it in a few minutes; it consists of a central 
part about 6 feet high surrounded by a narrow sandy beach; 
this beach and the sea are strewn with big and smaller frag- 
ments of rock, and an interesting live coral reef encircles the 
islet. The fiora is very poor consisting besides a few coco palms 
of a number of littoral plants: Premna integrifolia L., Calophyl- 
lum inophyllum L., Macaranga Tanarius L. was also represented, 
furthermore Terminalia Catappan L, Morinda citrifolia L., Guet- 
tarda speciosa L. Along the beach: Ipomoea pes Caprae Sw., 
Ischaemum muticum L., Scaevola frutescens Krause, and on the 
rocks small specimens of Cyperus cyperoides 0.K., and large 
bushes ot Cordia subcordata Bl. All these plants mixed with 
Saccharum spontaneum L. along the raised wall and Pogonathe- 
rum paniceum Hack. tormed a fairly dense vegetation. 
25 April. This day was set apart for an ascent to the top 
of the mountain. At starting the path led across the coco grove 
approximately parallel with the coast to the well-kept chief 
kampong of the island, which is connected with the coast by 
a trim road bordered with cocos and croton’ bushes. This kam- 
pong contains a large number of different fruit trees, and it is 
surrounded as before with neglected coco plantations with the 
thick undergrowth as described before, but after reaching the 
beginning slopes and having crossed a well-kept pepper- -garden, 
we found the surroundings different and we reached a peculiar 
wide-spaced forest consisting of but few~species of trees, the 
same as we had already met the day before. This forest is poor
