grown, a herd of the beautiful little Bali cattle being also kept for regular 
killing ; on these occasions the requirements of the official residents of 
Manokoeari were also taken into account. 
Genbela. 
Beyond Wousi secondary forest with Malay houses at intervals bounded 
the beach to Genbela, where fine sands run out to the cape that limits the 
bay to the east. In the forest the fungus *Favolus scaber, the lianes 
*Entada scandens and °Mucuna Kriitkei were collected. *Peristrophe 
jalappejfolia, *Hemigraphis reptans and H. dorensis, with * Geophila reniformis, 
formed constant undergrowth. On the edge of the sandy beach *Pandanus 
dubius grew in clumps, the young plants unbranched with thin leaves about 
3m. long; the old trees about 8 m. high, with many branched crowns and 
shorter leaves of much stiffer consistency, bore large round heads of glaucous 
mericarps. Behind this beach, on a level stretch of country with intermittent 
sago-swamps, the native plantations were mostly situated. 
Island of Roon. 
We stopped a day at Djendeé, the chief place on the island, of which the 
gneiss’ formation carries a mainland type of vegetation. Djendé lies in a 
deep sheltered bay, the native houses being all built over the water, like 
a miniature Brunei. It is surrounded by hills about 500’ high, which, from 
the little seen, seemed to carry a very interesting association of plants. 
Along the road bordering the bay, Anthoceros bullato-spongiosus associated 
with the minute mosses *Garckea phascoides and * Wilsoniella pellucida and 
young plants of *Lycopodium cernuum grew in the shade, while *Schleria 
margaritifera and °Otanthera novo-guineensis were found in the open. 
On the forest slopes °Cyathea runensis grew as undergrowth, where the 
orchid °Vrydagzynea elongata was growing sporadically with Centotheca 
lappacea ; *Trichomanes bipunctatum was collected as an epiphyte, also 
*Piper Forsteni in flower, with hanging yellow ? spikes, about 4 dm. long. 
The forest was in a very dry condition, rather a surprising fact, taking the 
heavy rainfall into account (p. 13), also considering it was the rainy 
season ; this fact again proves the fallacy of the all-embracing term rain- 
forest applied in general to all and sandry tropical forest formations. The 
actual rainfall is by no means the dominant factor, as it is the limiting 
characters, no matter how small their incidence, which have to be taken into 
account; that is to say exposure, soil, and drainage, while should drier
