41. Nineteen trees died during the year, and seven others were destroyed 
by storms. The major losses were Orania regalis Macrozamia hopei. Eucalyptus 
robusta, Rhopatoblaste hexandra, Phoenix rupicola, Mimusops elengi and 
Hydnocarpus anthelmintica. Thirty-one new plantings were done, the most 
interesting being Ervatamia sp. and Macadamia ternifolia . The planting of 
trees has always been a problem owing to the lack of adequate space. 
Consequently, this aspect of the Gardens work has been greatly restricted. 
Without further land to develop as an arboretum this aspect of the Gardens’ 
work must inevitably be greatly restricted. 
42. The multiplication nursery on Lawn Y now enclosed in a fence, was 
expanded by removing unwanted shrubbery which surrounded it. The old 
quarantine house was refurbished, and a telephone installed, to become the 
Plant Sales Office. This has greatly facilitated the plant sales service since the 
nursery and office are now on the same site. 
43. Preparation was made to close the Gardens entirely to all vehicular 
traffic to avoid congestion and dangers to visitors. In this matter the co- 
operation of the police had been obtained by allowing the vehicles to be 
parked outside. These arrangements have not been implemented, but are held 
pending. 
XXI. HORTICULTURAL EXCHANGE 
44. Exchange of seeds and plants with other botanical organisations in 
Singapore, Malaya and overseas remained an important aspect of the work 
of the Horticultural Division. However, only one man was engaged on seed 
collection throughout the year and the demand is much greater than can be 
met. Institutions with which exchanges were carried out are listed in 
Appendices VII and VIII. 
XXII. 1STANA NEGARA DOMAIN 
45. The grounds, including the immediate gardens of all the houses in 
the Domain, have been kept in good condition. Mechanical equipment gave 
good service. The infestation of Elephantopus scaber in the turf of the golf 
course (see Annual Reports 1960 para. 72, and 1961 para. 63) has been 
held in check. The golf course was also kept in good condition. The work 
at the potting yard and the vegetable and flower nurseries was maintained at 
a high state to provide for the households of the Domain. Nearly 2,000 pot 
plants were cultivated in the potting yard and additional plants were grown 
for trans-shipment to Kuala Lumpur for the grounds of “Temasek”. 
46. The grounds were open to the public by kind permission of H.E. the 
Yang di-Pertuan Negara on New Year’s Day (1st January), Chinese New 
Year’s Day (5th February), Hari Raya Puasa (7th March), Labour Day (1st 
May) and on Deepavali (27th October). 
XXIII. SINGAPORE HOUSE, KUALA LUMPUR — “TEMASEK” 
47. The Domain nursery was used to prepare planting material for the 
garden of this house. These amounted to 1,500 pots. Since these were shipped 
rooted in pots with soil, special permission had to be obtained from the 
Director of Agriculture, Federation of Malaya. The Curator made two visits 
to Kuala Lumpur to give advice on the garden works. 
XXIV. ORCHIDS 
48. The availability of extra funds has enabled plant collecting 
expeditions to be carried out during the year. The major ones have been 
referred to in Section XVI, Collecting. These expeditions resulted in 362 
orchid species being added to the existing living collection. Other plants
