which is helpful and time saving to those engaged in the study of any 
group. Dr. Furtado was also engaged in keeping up to date the nomenclature 
of plants cultivated in the Gardens, especially of those that furnish seed 
sent to other institutions. 
THE HERBARIUM 
The amount of material sent out on loan, especially to specialists work¬ 
ing for Flora Malesiana, increased considerably over the 1950 figures, the 
total being 4,891 sheets, sent to botanical institutions in Leyden, Bogor, Kew. 
Paris and Hawaii. 2,851 duplicates were received in exchange, the most 
important accessions being those from the Herbarium Bogoriense in Indo¬ 
nesia and from the National Museum in Manila. Contributions were re¬ 
ceived also from the Forest Department, North Borneo, and from the 
Department of Agriculture, New Guinea, this last being a welcome addition, 
as the Singapore Herbarium, except for the large Carr collection, is poor 
in material from this region. 
The Gammexane insecticide mentioned in last year's report as being 
used against insect attack in the Herbarium, has not proved entirely satisfac¬ 
tory. A slight attack of ‘herbarium beetle’ was discovered in the ‘Gardens 
Herbarium’, which is a separately housed collection of cultivated plants, and 
a programme of repoisoning with corrosive sublimate of the whole of this 
collection was begun. 
PUBLICATIONS 
Volume XIII, part 2, of the Gardens' Bulletin was published in Septem¬ 
ber. This was a mixed number containing papers.by Professor R. E. Holttum, 
Mr. J. Sinclair and Dr. C. X. Furtado. Prof. Holttum described a new 
Vanilla from Johore and published a revision of the family Marantacea;. 
Mr. Sinclair published the description of a new species of Knema, one of 
the Myristicaceas, found in South Johore and Singapore. Dr. Furtado con-' 
tributed a revision of six genera of Malayan climbing palms in which three 
new species were described. 
The third part of Mr. M. R. Henderson’s Malayan Wild Flowers was 
published by the Malayan Nature Society, completing the account of the 
Dicotyledons. 
The fourth booklet in the series Malayan Garden Plants was published, 
containing illustrations and descriptions of ten climbers. 
HORTICULTURAL WORK 
The Gardens were maintained in good condition. Well mown lawns, 
trimmed and tidy edges and hedges, neat and well weeded beds are of first 
importance in any public garden. The public responds to such surroundings; 
and remarkably little damage is done and very little litter left even by the 
large numbers of people who visit the Gardens at weekends and on holidays. 
ROADS, PATHS AND DRAINS 
No work was done on the roads or paths by the Public Works Depart¬ 
ment. In July the level of the Lake was lowered to allow the mason to 
rebuild 14 feet of the channel feeding the Lake. A footbridge of nibong 
palm was constructed over this channel. Small repairs to drains and water 
channels were done by the mason.
