been rich on the ridges. Many of the regular mossy-forest species have been ousted by the all-prevailing Sycopsis. Shall have to go to the valley bottom for most of the plants I expect to gather in the locality. October 20th. Cloudy day with little sun: mist on hill tops by 10 AM: intermittent rain from 10.30 through afternoon and early evening. Most of today's plants are weeds from about a native house in a Pandanus grove 1 mile NNW of camp (2800 m. alt.). Carex, Viola, Hyperium, Galium, etc. from the highlands mix with Fimristylis, Digitaria, Juncus, Kyllinga, etc. of lower altitudes in a rich weed flora numbering thirty species. Teerink returned from Habbema with a convoy of eleven Papuans and several prisoners. October 21st. Fine clear day: cloudy after 3.30 PM: No rain and no mist on ridge NW of camp (This ridge often quite clear when mist covers the high spur across the river farther N.-NW: although we are in ridgy country the ridges are lower than the main spurs and valley conditions prevail: This probably accounts for Cycopsis ousting the regular mossy-forest trees.) Temperature maximum 16.5 degrees - minimum 6.5. Collected down the main path to the second native house at 160 meters below camp. Cycopsis still the prevailing dominant of the valley forest, but these forests more like rain-forest in appearance. Tree ferns (Dicksonia) and Cyathea) numerous and also a very large Marattia. Upper rain-forest types other than Marattia are [illegible], Spirideus, Syrtandra, Villania, Solanum, Ficus, Mucuna(?). A curious thorny tree with large lobed leaves
