aruan ( Micropeltes chanos ) for about one month in the middle of the year, 
and some 50 or more of these vast fish (see photograph in Annual Report 
for 1961, Plate 6) which would indeed be an angler’s delight were fishing 
permitted, died. At first sight of their floating corpses, one immediately 
suspected tuba poisoning, but the Tilapia and carp were unaffected. Nor was 
there any possibility of weedkiller or insecticide poisoning since the stream 
feeding the lakes comes from enclosed, unoccupied waste grassland. 
XXIV. HORTICULTURAL EXCHANGE 
55. Seed and plant exchange continued to be an important aspect of 
the Horticultural Division’s activity. One seed collector was kept fully 
occupied. Exchange institutions are listed in Appendices VII and IX. 
XXV. ISTANA NEGARA DOMAIN 
56. The grounds, including the immediate gardens of the houses in the 
Domain, were maintained in good condition. All mechanical equipment gave 
satisfactory service. Because of the needs for decoration at receptions and 
official functions, special attention has been given to maintaining a plentiful 
supply of potted plants. Large quantities of burnt soil have to be prepared, 
and also of compost using cattle manure, horse manure and spent hops. The 
golf greens, tees and fairway swere keep in good playing condition. 
57. By kind permission of H.E. The Yang di-Pertuan Negara the 
Domain was open to the public on Chinese New Year (13th February), Hari 
Raya Puasa (15th February), Labour Day (1st May) and on Deepavali (3rd 
November). 
XXVI. ORCHID RESEARCH 
58. Collecting expeditions for obtaining living material for cultivation 
have been referred to in para. 42 and in Appendix VI. These resulted in 
237 numbers consisting of 1,266 plants being added to the living collection; 
340 plants of species and hybrids were received on exchange and 154 as gifts, 
206 mature plants, cuttings and seedlings were given on exchange. Individuals 
and institutions concerned are listed in Appendices VIII and IX. 
59. During the year 74 hybrids pods were harvested from the Gardens’ 
plants; 15 were received from Singapore growers, five from Malaya and 
30 from England. Of these 124 pods, 78 were successfully germinated. More 
than 2,000 flasks have been regularly in use during the year on this stage 
of orchid culture. 
60. The same unsatisfactory state of congestion in the orchid nursery, 
due to the lack of provision of adequate space, which has been recorded in 
the previous three annual reports, continues to hamper seriously the Botanic 
Gardens’ efforts to produce new material for amateur growers and the 
nursery industry. 
61. To mark the visit of H.E. The Governor of Trinidad and Tobago 
and Lady Hochoy on 30th June, Cross No. BGS. 2812, Den. Ursula x Den 
taurinum was named and registered as Den. Lady Hochoy.
