Piper Forstenii, Pothos, and various large-leaved root-climbers. Piles of 
these huge leaves accumulate under the trees, to be dispersed by the floods 
of the rainy season. A giant Korthalsia, its interlaced stems scrambling up 
and down the trees or spreading in tangled mass over the ground, was the 
only “rotan” seen. Asplenium Nidus was abundant ; but epiphytic orchids 
were few and far between, and the absence of flowers or fruits was most 
striking. 
In this forest there is little undergrowth. Sodden leaves mostly fill up 
the interstices of the porous korang. Where light shoots through, some 
thin grass or patches of the creeping Geophila reniformis and Hemigraphis 
reptans, or single specimens of the small semi-herbaceous shrub Amarocarpus 
Wichmannii, with horizontal dorsi-ventral branches, appear ; but the most 
conspicuous objects are the huge Zanonia capsules, the size of large 
pumpkins, in all stages of decay, scattered over the “ korang,” which is so 
porous that surface-water soon drains through; but where there is standing 
water, groups of Sago Palms occur, often forming swamps covering large 
areas. 
A track from Warén to the Arfak runs for a couple of days through 
Sago swamps. 
Native Plantations. 
These are dotted through this forest where little islands of soil accumulate, 
as at Warén, or alluvial deposits have been formed by the rivers, as at 
Wariap. Here the well-stocked “ kebuns ”! surprised me by their extent, 
many kinds of bananas and plantains, coco-nuts, papaya, cassava, “ kladi,” ? 
“ubi,”* “labu,”* egg-fruit, and various “ sayur”’° etc. being grown, with 
clumps of bamboo, probably planted. 
On passing through this “korang” zone we followed a new route, 
keeping to the south bank of the Momi, so obviating the necessity of 
crossing the river, which is rather deep at its mouth. This track passes 
through the Wariap plantations and the sterile ‘“‘korang” forest beyond, 
cutting off a great angle of the river. Then it skirts the shifting banks of 
the river as the latter cuts through alluvial deposits of mud and sand, 
or crosses wide sand-banks, the splash of crocodiles heralding our approach. 
These sand-banks afforded a fine view over the Momi, showing Casuarinas 
and the symmetrical Terminalia, the latter veiled in all-obliterating Zanonia, — 
backed by the distant mountains. Thence the track alternates between the 
dome-like “ korang ” forest and the thicker undergrowth of alluvial flats, or, 
when nearer the river, over oozy slime which spreads over the stems and 
leaves of a small Licuala palm and the giant Korthalsia, the chief under- 
growth in such areas.
