that time. This Herbarium is a small one but it contains many important 
Bornean collections. During his visit Mr. Sinclair was enabled, through the 
courtesy of Mr. Tom Harrisson, Curator of the Sarawak Museum, to visit 
and make collections at Mount Santubong. Kampong Segu. the limestone lulls 
near Bau, and at Buso. 
Mr. M. R. Henderson began the study of the genus Calophyllum of the 
family Guttifer*. This is a group of forest trees which are now providing 
a certain amount of commercial timber. They are. botanically, a difficult group, 
the Malayan species of which have never been properly understood. As a 
result their nomenclature is in confusion and must be straightened out as a 
preliminary to understanding what is available in the forest and what theii 
distribution is. Mr. Henderson continued work on his popular account of the 
Wild Flowers of Malaya, the first part of which is now published. 
Mr. Sinclair continued as far as possible with his revision of the Anno- 
nacece, but awaits material from Borneo and India which is being sent on loan 
from Kew and Dehra Dun. Loan material of this family has been sent by the 
Department of Agriculture, Thailand, and by the Sarawak Museum, and Mr. 
Sinclair took the opportunity, while on leave in India, to consult type material 
in the Herbarium of the Royal Botanic Gardens, Calcutta. 
Dr. C. X. Furtado pursued his studies of several genera of palms and 
completed manuscript revisions of the genera Korthalsia, Plectocomia -and 
Plectocomiopsis. 
The artist was kept fully employed during the year, executing mostly line 
drawings for the illustration of various botanical manuscripts, and also 
coloured drawings of new hybrid orchids and other plants. Mrs. Kinloch Smith 
presented a further series of water colour drawings of plants cultivated in the 
Gardens. These are of outstanding merit, both technically and artistically. 
The Herbarium 
A considerable amount of time bas been spent in getting together, listing 
and packing herbarium material for loan to various specialists, in particular 
to those botanists working for Flora Malesiana. 2,046 sheets were sent out on 
loan during the year, and in addition a large number of spirit specimens 
were sent to a specialist studying figs and fungi. The proper packing of such 
specimens is laborious and slow. These despatches interfered to some extent 
with the normal exchange of duplicate material, and although a considerable 
quantity was ready to be sent out, only 706 sheets could be sent. 1,601 
tiuplicates were received from other institutions. 2.141 sheets were mounted 
and incorporated into the herbarium during the year, a smaller number than 
usual, as the mounters were engaged on a programme of repairing old her¬ 
barium sheets. 
Eleven new sets of herbarium cases were purchased. These were filled 
by the overflow from the existing overcrowded cases, and as there is no room 
for further cases in the Herbarium building, extensions will be required in 
the near future. 
Very considerable collections were received from the Forest Department, 
North Borneo, and Mr, Sinclair spent much time in naming those,
