amounting to 426 species and hybrids were also received from outside sources 
on exchange from Singapore, Malaya, Sarawak, Brunei, New Guinea, India, 
Nigeria, Costa Rica, Venezuela, Abyssinia, Kenya and Hawaii; and 115 
orchid species and hybird plants of diverse and worldwide origin were obtain- 
ed by purchase from nurserymen. Against the plants received on exchange, 
some 396 were given in reciprocation. 
49. Sixty-seven hybrid pods were harvested from the Gardens nursery, 
seventeen were received from Singapore growers, eleven from the Federation 
of Malaya, sixteen from New Guinea, six from Sarawak and one from Brunei. 
Of these 118 pods, seeds from 89 of them have been successfully germinated. 
About 2,000 flasks are being used for the young seedlings. During the year 
the contents of 553 flasks were potted out. The flask culture medium used, as 
previously, is based on Vatin’s formula plus 10 per cent coconut water and 
banana pulp. Trails with “Pepton” in the absence of coconut water and 
banana pulp gave encouraging results. 
50. A total of eight hundred and ninety-five seedlings were potted out 
from the seedling houses and planted in pots outside, but the lack of planting 
space will hamper appreciably their further progress. 
51. The following crosses were registered during the year:
