Mr. E. J. H. Corner made a joint expedition to the East Coast with 
Mr. W. Birtwistle, Officer-in-Charge of the Fisheries Department. For the 
first half of the trip they had the use of a launch provided by the District 
Officer, Kuantan, to whom grateful thanks are offered for this assistance. They 
were able to visit Pulau Tioman and other outlying islands, including 
P. Berhala, and to stop at several small villages on the Pahang coast. 
Mr. Corner took the opportunity of investigating the sand dune flora, especially 
the habitat of Casuarina equisitifolia, which colonises the large sand banks at 
the river mouths. P. Berhala also presented many points of ecological and 
botanical interest, and it is intended to write a special report of this part of 
the expedition. In Kemaman, Mr. Birtwistle and Mr. Corner were the guests 
of Mr. E. T. Swan, who very kindly put his house at Bukit Kajang and his 
means of transport through the forest at their disposal. Mr. Swan thereby 
showed the way to an extremely rich and almost unexplored botanical field, and 
our very best thanks are tendered to him, with the hope that another visit will 
be possible later. Mr. Corner studied the riverside flora of the Kemaman 
and Nipa rivers for comparison with the Sedili in Johore, as well as provisionally 
the immediate neighbourhood of Bukit Kajang, where several interesting plants 
were discovered, including a magnificent new species of Dysoxylon with very 
large fruits and a very floriferous new species of Paraboea. Mr. Corner also 
collected a large number of fungi. About 400 numbered collections of plants 
were made in all. 
Mr. Corner also made a number of short excursions to southern Johore, 
especially to the Sedili river and its surrounding forest. On some of these 
visits he was accompanied by the Director and by Mr. C. E. Carr, whose expert 
knowledge of orchids was of great service in attempting to work out the peculiar 
flora of this region. Special attention is being given to the trees of the fresh 
water tidal swamp, and to the zonation along the river, and many species 
hitherto regarded as rare or unknown in the Peninsula have been found to be 
abundant in this area. During the latter part of the year Mr. Corner also 
took the opportunity of visiting one of the last remaining patches of swamp 
forest in Singapore (near the 15th mile, Jurong Road) as it is in process of 
being felled. This forest is as near to being in a virgin condition as could be 
expected, and many of the species are the same as occur in the swamp forests of 
Johore. The possibility of studying each tree in detail as it is felled has enabled 
correlation to be made of characters of leaves and flowers with those of the 
base of the trunk, thereby giving valuable clues to the identification of standing 
trees in the Johore forests. Many of these trees have remarkable upward- 
growing roots and other curious growth habits, and no proper investigation 
of these has ever been made, largely owing to the difficulty of access to the 
swamp and to the greater difficulties of distinguishing the roots of one tree 
from another in the profusion of growth, and of finding criteria for 
distinguishing the trees in the field, where only the bases of their trunks are 
ordinarily accessible. Mr. Corner through his energy and persistent efforts 
has made great progress in investigating these very interesting plants. 
During the months July to September, one of the Gardens Plant Collectors 
was attached to the Oxford University Sarawak Expedition. In return for 
services so rendered, a set of specimens collected by the Expedition has been 
promised. 
HERBARIUM WORK AND OTHER INVESTIGATION 
During his absence on leave (which was extended for the purpose) 
Mr. Henderson spent the months of March, April and May working in the 
Herbarium of the Royal Botanic Gardens, Kew, studying critical material 
collected in recent years. A considerable number of new species and additions 
to the Peninsula Flora were discovered among this material, the most interesting 
being from Cameron’s Highlands and from the limestone areas, to which 
Mr. Henderson has paid special attention in his collecting during the past 
few years. A number of specimens of recent collections by the Forest 
Department w T ere also studied. The opportunity was taken to photograph 
Herbarium specimens of Malayan plants not represented in the Singapore 
Herbarium, and about 200 negatives were made. Thanks are due to the 
Director and staff at Kew, and to Mr. H. N. Ridley and Mr. I. H. Burkill fo t 
their interest and help. After his return to Singapore, Mr. Henderson 
prepared a paper embodying part of the results of his work at Kew, and it 
is hoped to publish this early in 1933.
