region — by Nakai in the Rhio Archipelago. The plant is A. truncata (Wiild.) 
Spr. and twining appears to be an unusual' habit-form. 
48. The expedition in the Ipoh district was made under the guidance 
of Mrs. B. E. Allen, a resident of Ipoh, who is an acknowledged authority on 
Malayan Pteridophyta. Opportunity was taken to collect on Gunong Bujong 
Malacca and Gunong Tempurong, limestone hills where the vegetation is all 
being burnt off preparatory to mining operations. Collections were also made 
at Bukit Batu Suloh and in the mining area of the Kinta Valley. 
49. The collections made at Fraser’s Hill, while Mr. Burkill was on 
casual leave, yielded two probably new orchid species. Further material will 
be sought at the next opportunity to send living plants to the Royal Botanic 
Gardens Kew where cultivation is more likely to be successful than in the 
humid heat of Singapore. 
50. Mr. Alphonso visited the Crocker Range in North Borneo in search 
of material to introduce alive to cultivation in Singapore. A number of aroids 
was successfully brought back. Collections were made near Tenom, Tam- 
bunan and Patau, on the Keningau Plateau and on the Bainio and Biak 
Rivers, also at Bau in Sarawak. The weather was extremely wet making the 
field work very arduous. Nevertheless no botanist can always be a “fair 
weather” field worker and as the flora becomes better known collections in the 
wet season are possibly more likely to produce novelties than other times. 
51. Mr. Burkill continued his collections of marine algae at Raffles 
Light, Singapore, and the nearby islands, and made smaller collections at 
Malacca and Port Dickson. An inspection of the northern portion of Jason 
Bay, by Kuala Sedili revealed only one single algal specimen, Hydroclathrus 
clathratus, but no mud-dwelling species for which the muddy coastal strand 
would seem suitable. Unusually large specimens of Valonia ventricosa J. Ag., 
up to 3 inches across were found on the coral reef of Pulau Hantu. 
52. Beside the phanerogamic collection at Fraser’s Hill, Mr. Burkill 
collected 34 numbers of lichen and 20 of mosses. The lichens together with 
others from Singapore and Kuala Sedili area were sent to experts in London 
and Holland for naming. 
53. On most of these trips in Malaya samples of water from streams, 
ponds and swamps were taken for sending to Dr. Prowse at the Fish Culture 
Research Station, Malacca, for his work on phyto-plankton. Samples of water 
were sent from the Botanic Gardens Lake; Fraser’s Hill; Kinta Valley, Perak; 
94th mile Manchis Road, Pahang; Muar River near Gemas; Kota Tinggi; 
Kuala Sedili swamp, and central Johore.
