quite distinct from anything in ferns so far familiar. *Angiopteris evecta was 
abundant, and Alsophila straminea well represented. Begonia humboldtiana 
with mottled leaves and pink flowers grew all along the banks in large 
clumps, but it was impossible to find any normal fruit, the capsules being 
all swollen through the action of some insect. Ficus conocephalifolia, most 
aptly named, with enormous leaves and bearing red receptacles, was a 
common tree. 
Bosnik, on the Island of Wiak. 
On the return to Manokoeari, half a day spent on Bosnik, on ene of the 
Schouten Islands, was interesting, it being the first time the steamer had 
called there, this new Government station having been built as an alternative 
to Mosmer as a point of call. The island is coral-limestone, a high ridge 
rising behind Bosnik, and low-lying flats in front of the latter are rapidly 
being cleared for the “campong” plantations. 
Under the strand trees bordering this area *Cycas circinalis, the ferns 
*Dryopteris stenobasis, *Diplazium polypodioides, with *Fleuria ruderalis, 
Ophiorrhiza insularis, Piper bipunctatum, and P. bosnicanum, the latter 
epiphytic on a tree, were found. 
As this was quite a new station, the strand trees were not yet stripped 
of their epiphytic treasures, and one splendid example, a veritable garden of 
various plants, yielded *Lycopodium phlegmaroides, *Psilotum flaccidum, the 
orchids °Hippeophyllum alboviride, Dendrobium inconspicuum and °D. potomo- 
philum, °Eria rigida var. papuana, and °Sarcanthus bicornis, all with incon- 
spicuous flowers, with the handsome Medinilla rhodorhachis with pink 
flowers. 
All the streams drain through the “korang” into the sea at the beach 
level, so that it is possible to drink fresh water from the salt. 
At all the other stopping-places the time was too short to do more than 
collect a few plants, or, the islands being entirely under cultivation, possibilities 
in collection were limited to the beach. 
SYSTEMATIC RESULTS. 
Over 330 plants were collected in the Arfak, of which 100 have proved 
new to science, with one new natural order and five very distinct new genera. 
Of the new species perhaps the most interesting are a Dacrydium, the first 
species in fruit to be described from New Guinea, a Libocedrus, a genus new 
for Dutch N.W. New Guinea, anda Kentia. A new species each in Trimenia, 
Telminthodia, and Backhousia, establish Papuan preponderance in those 
genera, while a new species in Patersunia, Centrolepis, and Hibbertia represent 
new generic records for New Guinea.
