the character of the primitive forest is more influenced by the geological forma¬ 
tion than is the secondary growth which develops on cleared areas. It is certain 
that the ground flora of the forest on the Raub Series rocks near Tembeling and 
Jerantut is very characteristic. 
Messrs. Corner and Henderson visited Pahang in May and June, there 
being a good flowering of forest trees. Particular attention, was paid to these, 
and good series of flowering and fruiting specimens, with a wood specimen of 
each, were obtained. In a small area of forest near Tembeling, which had 
previously been several times visited, six trees were found in flower which had 
never been previously collected in the Peninsula; some of these are probably 
new species. A short visit was paid to Sungei Ketil, at Gua Ninik in Kelantan, 
where the river bank flora was examined. An attempt w r as made to ascend the 
Sungei Tekai, a tributary of the Tembeling, but in the time available it was not 
possible to get beyond the flood-damaged area. In flood-damaged forest near 
the river bank was found Keenania sp. a representative of a small Himalayan 
genus of the family Rubiaceae. Mr. Corner also collected a large number of 
fungi. 
In July the Director accompanied the Chief Agricultural Officer, Johore, on 
a short visit to the swampy forest bordering the Sungei Endau. Thanks are 
due to the Government of Johore for the opportunity of making this expedition. 
Several interesting plants w T ere found, including undetermined species of the 
following genera: Wendlandia (Rubiaceae) Tristania (Myrtaceae) Medinilla 
(Melastomaceae) Millettia (Leguminosae) and Toxocarpus (Asclepiadaceae). 
Various interesting collections of ferns were also made. On the return journey 
a halt was made at Tanjong Selantai and there the fern Brainea insignis was 
found growing abundantly; this is the most southerly record for this interesting 
species, which has its chief distribution from Burma to southern China and has 
never before been found on the mainland of the Peninsula (only at Pulau 
Rumbia, Lower Perak). 
In September the Director paid a short visit to Cameron Highlands, at 
the request of the Highlands Development Committee, to report on the area 
called Taman Sedia. Similar areas were located near Brinchang Camp, and 
on one of them was found a member of the family Compositae, Ainsliaea reflexa 
Merr., only known previously from the Philippines and Formosa. Also in the 
valley of the Sengam river were found for the first time in the Peninsula the 
ferns Osmunda javanica (of which living plants are now growing in Singapore) 
and Microlepia strigosa (not previously known south of Langkawi). 
In October Mr. Henderson visited several Limestone hills in Pahang, in 
continuation of his visits to the limestone districts of the Peninsula. The small 
hill known as Bukit Chintamini, 11 miles south of Bentong, was first visited. 
Here Calanthe ceciliae was found in abundance. Bukit Serdam at Raub was 
climbed, but proved disappointing. There is little outcropping of limestone, 
and the hill appears to be covered with a very stiff slippery red clay, which 
supports a poor type of secondary growth. The isolated group of limestone 
hills near Kuantan was visited, and the largest, Bukit Cheras and Bukit Sagu, 
were collected upon. Impatiens Foxwoi'tkyi Hend. and I. Scortechinii Hook 
fil. were found in full flower. Both these hills gave a number of very interesting 
plants, some of which are not yet identified, and will repay further visits. 
Mr. V. B. C. Baker (General Manager of the Pahang Consolidated Co), and 
Mr. & Mrs. D. A. Bett are warmly thanked for their hospitality during this 
visit, and for free permission to use the Company’s transport arrangements. 
The Director made a short expedition to British North Borneo in November 
and December, joining the Clemens Expedition on the slopes of Kinabalu. 
Thanks are due to the Government of British North Borneo, to the Resident, 
East Coast, and to the District Officer, Kota Belud, for assistance in making 
transport arrangements, and for permission to collect some orchid plants; and 
to Mr. and Mrs. Clemens for hospitality and much kind assistance. Attention 
was chiefly confined to ferns and mosses, as it was impossible in the time avail¬ 
able to deal with all classes of plants; opportunity was found however to collect 
specimens of a number of the peculiar plants of Kinabalu which were not pre¬ 
viously represented in the Singapore herbarium. About 300 species of ferns 
were found, and living plants of some of them were brought to Singapore. 
Living plants of Nepenthes villosa and N. rajah w 7 ere also taken, and are now 
growing on Penang Hill. It was found possible to ascend the mountain, and 
this was done by the Tenompok route. Collections were made all along the
