Lawn S . Part of the G-ardens Jungle. A dead tree, and another 
which had fallen were removed, and some plants put in to 
fill the gap. 
Lawn T . Grass cutting. Two plants of Burkillanthus malaccensis . 
an interesting Malayan forest tree of the Citrus family, 
never before cultivated, were planted. 
Lawns U <Sb V . (Gardens Jungle). 42 young trees were planted in 
an open place in the Jungle between Liane Road and the 
Burning yard. 
Grass cutting. The thickets round the bases of the rattans 
on this lawn were cleaned of much rubbish and the rattans 
given a little rock phosphate. A start was made at dig- 
ging and manuring the many palms on this lawn needing 
attention. A dead palm and a small dead tree were removed, 
and a new tree ( Castanospermura australe ) planted. 
Grass cutting. One overgrown bamboo removed. 
(Vegetable Garden <Sb Nursery). 
Work on this lawn' was continued from August. All young 
trees were dug and manured, two new Gnetum trees planted, 
and grass cutting completed. 
The planting of hybrid seedling Bougainvilleas and bulbs 
on the site of the Assistant Director's tennis court was 
completed, and also a large number of Hibiscus and Ixora 
varieties for which there is now no room in the Nursery. 
The planting of Gannas was begun.

Dr. Purtado continued his study of the rattans of the genus 
Calamus. He completed the naming of all specimens from Malaya. 
He then prepared a new classification of the genus into sections, 
as his new information had shown the old divisions unsatisfactory, 
and drafted keys to the sections and to all Peninsula species. 
These draft descriptions of sections and keys are still not complete 
but satisfactory progress is being made. Dr. Purtado has also 
prepared descriptions of 3 new species of Calamus from Malaya. His 
survey shows that about 6o species of Calamus are at present known 
to occur in the country, of which about 12 are new. 
10. Mr. Holttum's botanical work . 
Mr. Holttum spent some time in naming trees in the Gardens, 
and in collecting notes on the various Albizzia trees, which are not 
all named. He described two new orchid hybrids which flowered 
during the month. He also made notes on 3 hybrid Bougainvilleas 
seedlings which have flowered for the first time, of which one seems 
worth keeping for further trials. He continued his work on ferns, 
studying the remaining genera in the Dryopteris sub-family, Bolbitis, 
Egenolfia, Stenosemia, Quercifllix, Gyclopeltis and Didymochlaena. 
His studies indicate that a change in the management of some species 
included in Tectaria should be made, and he is attempting to re- 
define the genera.
