28, The first visit, 2nd August, was to the Semengoh Forest Reserve or 
“Arboretum” where many of the trees have been labelled and are protected. 
Here Mr. Anderson makes frequent visits, always on the look out for trees 
in flower and fruit. A tree-house has been erected here where one can observe 
temperature, humidity and other meteorological data at various heights in 
the forest throughout the year. The forest was notable in that it contained 
a good many members of the Sapotaceae not seen in Malaya. Here also the 
Myristicaceae were fairly abundant and Knema raja, a rare species collected 
by Beccari once only and in flower, was discovered by Mr. Sinclair on the 
first day of the trip. This was indeed fortunate for K. rufa was one of the 
special plants required for the monograph and it was seen in fruit for the 
first time. It was again obtained at Gunong Gaharu in fruit and at the Andulau 
F.R. in Brunei in male flower. Two more visits were paid to this forest 
reserve, namely on 3rd and 11th August, where it was relatively easy to 
collect material since one could choose from the numbered list any special 
tree that was wanted from which an expert tree climber provided by the 
Forest Department could collect specimens. From 4th-9th August the party 
went to Gunong Gaharu and Sungei Sabal Tapang, some 80 miles inland, 
near the Indonesian border. Mr. Smythies came also and Mr. Anderson 
arrived on the 6th. Accommodation was found for the party in a house 
belonging to a Chinese who was extracting “belian” logs, Eusideroxylon 
zwageri from the forest. The only persons to collect in this area previously 
were Nahar, a forest guard from Kuching, and Asah, the Forest Department’s 
tree climber, who both made a preliminary visit to prepare for the advent 
of the Singapore party. They searched for Myristicaceae and these were 
shown to the Singapore members on arrival. Rare and little collected plants, 
obtained from Gunong Gaharu were Macaranga setosa, Mammea anastomosa, 
Paramapania radians, Aporosa, a new genus according to Airy-shaw, Knema 
rufa, K. ashtonii, Gonystylus borneensis and Aetoxylon sympetalum. Upuna 
borneensis, a very tall endemic Dipterocarp reaching to 180-200 feet, was 
plentiful. 
29. A day was spent at the Bako National Park of which Mr. Anderson 
is warden. On the top of the ridge above the rest house is the stunted 
“kerangas” or padang vegetation. “Kerangas” is an Iban word meaning 
ground on which paddy will not grow. The substratum consists of podsolic 
sand, sandstone rocks and peat. A few plants are now mentioned which occur 
here and are representative of such a community:— Cotylelobium fiavum, 
W hiteodendron moultonianum, Tristania obovata, Calophyllum nodosum, a 
peculiar species from 6 inches to 1 foot high, looking very much like a 
Vaccinium, Alyxia pilosa, Vaccinium borneensis, Burmannia aisticha Dacry- 
dium beccaru var. subelatum, Schoenus calostachys, Tetraria borneensis 
and a new species of Casuarina formerly confused with sumatrana. In a stream 
at the foot of the hill Dipteris lobbiana was obtained while Spilanthes urens 
a Composite with white flowers and the margins of the inflorescence bracts 
purple, was obtained creeping on the sand near the rest house. Here it was 
rare but was again found in some quantity at Muara Beach in Brunei The 
latter record is the first for this species in Brunei. The plant has been found 
before at Si bu and in North Borneo but the Bako record is the first for the 
1st Division of Sarawak. 
30. The visit to Matang on 13th August was a rush and the actual 
summit was not reached Good fruiting material of the rare KnZapecHnam, 
also once collected here by Beccari in flower, was obtained at 2,000 ft. Near 
it were male and female trees of K. cinerea var. cordata in flower The 
character of the flora began to change above this point when some crags 
were reached. Here there were some unique and interesting plams such fs
