Argostemma borraginea, Steensia borneemis, Stilphonothrix ornata and ferns 
such as Diplazium porphyrorachis, Tectaria grandidentata, T. angulata and 
Thelypteris beccariana. 
31. The visit to Lundu and Gunong Gading lasted from 15th- 19th 
August. This mountain and the Gunong Puey Range have some peculiar 
plants and are composed of granite while most of the rocks in the 1st Division 
are of standstone. The granite ranges have not been inundated in recent 
geological times like the sandstone coastal areas and this may account for 
some of the peculiar plants found at Gading and Puey. A few rarities or 
endemics may be briefly mentioned here. G. Gading (1) base of mountain 
to waterfall — Hallieracantha caudata, Piptospatha insignis (the type locality), 
Heterogonium stenoseminoides, Streblosa urticina and a new variety of 
Knema latericia which also occurs higher up in the mid-zone, (2) above the 
waterfall — Goniothalamus rufus, Popowia odoardii, Aglaia unifoliata (3) 
summit — Loxocarpus longipetiolatus, Vaccirdum borneense var. poianum, 
Ctenopteris repandulum and Lindsay a parol lelogramma. 
32. A 3-hour trip by speed boat in the same area was made up the 
Batang Kayan to Gunong Meroyong, Sampadi Forest Reserve. Here there 
was a kerangas ridge where the following were obtained: — Dipterocarpus 
rigidus, Elaeocarpus chrysophyllus, Ginalloa linearis (a parasitic mistletoe), 
Nepenthes albomarginata and a new species of Horsfieldia, Hosea lobbii , 
an attractive Clerodendron~l ike a climber with orange-pink flowers and 
inflorescence bracts — was conspicuous and common in many places along the 
banks of the Kayan River. 
33. On 25th August Mr. Sinclair and Che Kadim left Kuching by air 
and arrived at Brunei Town. They were met by the State Forest Officer, 
Inche Mohd. Yakin bin Long, and directed to Seria where headquarters were 
set up and a programme was planned. Thanks are especially due to the State 
Forest Officer and the Brunei Government who provided free transport to 
all the collecting sites as well as several assistants and a tree climber. The 
Keeper is deeply indebted to the Forest Department for providing a special 
motor launch for a trip from 29th-31st August up the Sungei Belalt to Bukit 
Puan and back. The Singapore party is also indebted to the late Haji Abang 
Suhaili, District Forest Officer, Kuala Belait, and his men who accompanied 
them on all the excursions and arranged the details of each trip. 
34. On 24th August a short visit was paid to Anduki Forest Reserve, 
Seria. Here the forest was composed of almost a pure stand of “Kapur paya”, 
Dryobalanops rappa, a tall timber tree with a mast-like trunk 100 feet or 
more in height. On the morning of 25th August a visit was paid to the forest 
at Sungei Lumut and in the afternoon to Andulau F. R. (North). In the former 
place the monotypic Ericaceous genus Costera ovalifolia, a crown epiphyte 
on Myristica lowiana was collected. In a swampy peaty area a pitcher plant 
Nepenthes bicalcarata and a tall dipterocarp, “Kukup”, Shorea pachyphylla 
were taken. In the letter place an interesting palm with stilt roots, Eugeissona 
minor, “tunjang pipit”, was collected. This tree is well-known locally for the 
excellent walking sticks which are made from the stilt roots, the handle being 
fashioned from the rhizome or stem-like portion where the stilt roots are 
attached. 
35. On 26th August another trip was made to Andulau F.R., but at its 
western sector. Here some interesting Myristicaceae were obtained, some of 
which are new. A huge Nephelium species, a kind of wild “pulasan” 120 ft. 
high and probably new, was discovered. The fruits were found to be very
