for addition to the Gardens herbarium. Permission to collect in the nature 
reserve of Korinchi was obtained from the Government of Netherlands India. 
The Director also paid a short visit, from Penang, in September, to the 
vicinity of Kampong Naka, Kedah, recently opened up by a new road. The 
vegetation is largely of a secondary nature, but a number of interesting plants 
were found, including an oak not previously known in the Peninsula, a new 
Peristylus, a rare bamboo and some little-known grasses. In connection with 
this visit the assistance of Mr. W. N. Sands, Principal Agricultural Officer, 
Kedah, is gratefully acknowledged. 
The principal field expedition during the year was made, with the 
permission of Government, by Mr. C. E. Carr, who was employed for the 
purpose on a temporary basis. Mr. Carr spent several months on the slopes 
of Mount Kinabalu, British North Borneo, and collected nearly 2,000 numbers, 
with little duplication, including nearly 700 species of orchids, which he made 
his special study. A considerable number of the orchids are new species. The 
whole collection is an exceedingly valuable one. 
HERBARIUM WORK AND OTHER INVESTIGATIONS 
Mr. Henderson’s report on work in the general herbarium 
The beginning of the year was mainly occupied in the completion of a 
paper or additions to the flora of the Peninsula. This was published in the 
Gardens’ Bulletin in May, and in it 45 species were recorded as new to the 
flora, 29 of them being described as new to science. 
From August onwards Mr. C. E. Carr’s extensive collections from Mount 
Kinabalu, British North Borneo, were worked over and preliminary identi¬ 
fications made. 
During the year a considerable amount of material was sent in for 
identification by the Rubber Research Institute and planters in connection with 
’’rubber forestry”. This material is almost wholly of plants growing as natural 
cover under rubber, and as a rule the specimens are scrappy and sometimes 
not well preserved, so that it is not always possible to identify them further 
than the genus. From a botanical point of view this material is usually 
uninteresting, but occasionally specimens are sent which show interesting 
extensions of the known range of the plant. Salvia prinoides, a South 
American Labiate, was sent from Bukit Paloh, Johore, where it is described 
as being fairly common amongst the natural ground cover. It has no doubt 
been introduced, but it has not previously been recorded from the Peninsula. 
Hyptis capitata, a Mexican Labiate, was sent from Selborne Plantation, Pahang. 
It has been recorded only once before from the Peninsula as an introduction. 
Eupatorium odoratum, a shrubby Composite of American origin which is 
considered to be a serious pest in Siamese forests, has been found to be spreading 
rather rapidly southwards and is now known from the North Johore border. 
Some estates are now building up small reference herbaria of named 
plants, and in one instance a number of sets of named and mounted specimens, 
amounting to about 800 sheets, was supplied at a charge which covered cost 
of collection, preparation and materials. 
An investigation into the varieties of Derris cultivated for “tuba” was 
undertaken with a view to providing a simple method of distinguishing them 
in the field, and a short illustrated paper was ready for publication at the end 
of the year. 
Approximately 4,000 sheets were mounted during the year. Of these 
approximately 2,000 were of specimens acquired by exchange. 
During the early part of the year, Mr. C. X. Furtado, Assistant Botanist, 
was employed in preparation for the studies of palms he later carried out at 
Berlin.
