Mr. Corner has continued his observation on the seasonal appearance and 
rates of development of the fungi in the Gardens Jungle. A wooden frame 
(8x6x3 feet), covered on the sides and the top with mosquito-proof wire 
netting, was made for the purpose of growing the timber-destroying fungi and 
observing the rate of development of their fruit-bodies. It was designed to 
Beep out monkeys, squirrels, snails, flies, beetles and the other numerous animals 
which have caused much annoyance hitherto by eating or breaking the fruit- 
bodies, and it has proved very effective. It is kept in a shady part of the 
Potting Yard and the infected logs of wood are placed inside and watered twice 
a day. 
The Director continued his observations on the periodic leaf change and 
flowering of trees in Singapore, and published a paper in the Gardens Bulletin 
summarising the results of three and a half years work on this subject. As 
indicated in the last report, these results indicate that some trees change their 
leaves annually in Singapore, usually in the early part of the year; some change 
regularly twice a year, about February and August; and a number of others, 
though annual in their behaviour in regularly seasonal climates, here change 
their leaves at approximately equal intervals which are not twelve or six months, 
individual trees behaving differently from others of the same species. There 
are also some trees which are very irregular in their behaviour, being influenced 
probably by small fluctuations of climate; the most notable of these is the para 
rubber tree, Hevea brasiliensis, individuals of which undergo partial or com¬ 
plete defoliation at different times of the year in successive years. 
The Director also continued the experimental cultivation of orchid seed¬ 
lings. During the year a number of plants of the hybrid Spathoglottis aurea x S. 
plicata flowered, the first plants about 27 months from seed. It appears that 
this hybrid is quite free-flowering in Singapore; it has large flowers of a pale 
yellow with pale purplish markings. Other seedlings continued good growth 
during the year, and a number are now well established in pots. A detailed 
report on them was published in the first number of the Malayan Orchid Review.
