90 Pengagl Creek elements there: Anaphalis lorentzi and A. sp., Stypheila, Vaccinium, Wahlen- bergia, Pterostylis, Haloragis 2 spp., and several grasses. In brushy growths on the edge of the bog I found climbing one of the Apocynaceae - a lowland element. Olearia and Dodonaea viscosa comprise most of the brush; a red Rhododendron (collected at Piunde-Aunde?) also there. The last three cold nights have considerably lowered my average of catches at the light trap; the dull weather, and cool temperatures during the day reduce the butterfly catch. During a short spell of sunlight this morning I netted a fine gomphid - the second dragonfly for the mountain. Three parties out until after eleven with jacklights last night brought home a very big Phalanger vestituys (Kim) and a small brown Pseudocheirus (John). Nothing special in traps, but yesterday an Anisomys, the first for the mountain, was taken in a steel set by Tobram. Since our arrival at this camp I have been searching the forest for Xanthomyrtus, one of the characteristic trees of the forest (of LJ.B.). This morning I found two trees. Some natives happened to be there at the time. They gave me the Chimbu name for the tree (EN) and said it grew in abundance along the mountain trail, somewhere below the glacial valley. I did not recognize it on the journey up or down, possibly because of the poor visibility in the forest. Shall have to climb the slopes until I find it. Friday, July 17. Max. 17, min. 5 C. A fine, bracing morning, mostly sunny. Afternoon soon overcast; light rain from a thunderstorm over Bundi Gap from 4:15 to 8 p.m. Was obliged to stay in camp this morning to prepare the bi lot of plants collected yesterday (still have some of them on hand). As I was photographing an orchid about 11 o'clock an armed constable walked into camp with more mail from Kundiawa. Held him for a couple of hours while we replied to some of our letters. Went down the road toward the airstrip after lunch. Tried to reach the main creek where a native pig bridge crosses it, but could not find the track. Poking about/the forest on the edge of the gorge of the creek, I came to a distinct change at about 8700 ft. (3650 m) if the top of the airstrip is 8500 ft. A scale-leaved Podocarpus (P. imbricatus?), not seen on the mountain before, became a common tree reaching large size in the canopy layer. Other unfamiliar canopy trees included one with the heavy branching habit of Nothofagus , a big- leaved Quintinia, etc. This change of the forest took place not far above the topmost gardens on the slopes, and might have been expected as an indication of cultivable land. Another Pseudocheirus forbesi shot by John last night; this morning, in a new trapline on Piunde-Aunde Creek, he had two Peroryctes ornatus and two Melomys. Van had in all 18 mammals on his table. Jacking up the creek by Van last night yielded no mammals, but he collected near the water 15 frogs of 3 species. Three or four individuals of one species of frog carried, completely buried under the skin of a leg or the belly, one or two big, thick leeches. Looks like a very interesting record.
