been received from Mr. M. G. Dickson of Kuching, Sarawak, and no fewer 
than three small collections from Mount Kinabalu in North Borneo have been 
examined and named. 
The Herbarium continues to receive considerable accessions of material 
from overseas institutions. Only 1,009 sheets were sent out this year, but 
3,263 were received. The largest consignments came from the Herbarium 
Bogoriense, Indonesia and the Rijksherbarium in Leiden. Other donors were 
the Arnold Arboretum in America, the Forests Departments of North Borneo, 
Dehra Dun in India and Lae in New Guinea, the National Museum in Manila 
and the University of Delhi. 
Botanists working on Flora Malesiana, the vast project sponsored jointly 
by the Indonesian and Dutch Governments which aims at publishing a com¬ 
plete and up-to-date Flora of the whole Malaysian region, are obliged to 
study material from the Singapore Herbarium and this is freely loaned to 
recognised botanical institutions for the use of specialists engaged in revising 
particular groups of plants. This year Flora Malesiana botanists have asked 
for and received no fewer than 6,905 sheets from Singapore, considerably 
more than in past years. Loans made in previous years are now beginning to 
be returned. The Singapore Herbarium benefits greatly from this study of its 
collections by overseas botanists, for much previously unnamed material is 
now named, mistakes are rectified and gaps are filled. 
PUBLICATIONS 
A paper on Bornean Annonaceae by Mr. J. Sinclair was published in the 
Sarawak Museum Journal Vol. 5, No. 3, in which three new species were 
described. 
The fifth booklet in the series Malayan Garden Plants, describing and 
illustrating ten palms of horticultural interest, was published and put on sale. 
It was not possible to issue a Gardens’ Bulletin, but material for a further 
number was sent to the printer towards the end of the year. 
A second edition of Mr. E. J. H. Corner’s Wayside Trees of Malaya 
printed by the Government Printing Office, Singapore, appeared during the 
year. This work has been completely reset and contains additions by the 
author to bring it up to date. All the line and half-tone blocks which illustrate 
this book were carefully preserved in the Botanic Gardens during the Japanese 
occupation and survived intact. 
Plans for a new Flora of Malaya to replace the present standard work, 
Ridley’s Flora of the Malay Peninsula, now out of date, have begun to 
mature. The first volume of the new Flora, which is to be a complete, illus¬ 
trated account of all the orchids native in Malaya, as well as the hybrids and 
the commonly cultivated exotic species, written by Professor R. E. Holttum, 
was in the final stages of proofing at the end of the year. This book will be 
indispensable not only to the systematic botanist and orchidologist but also 
to those who grow orchids in their gardens or are interested in producing new 
hybrids, for it contains much information on cultivation and on the raising 
of orchid seedlings. 
Descriptions and photographs of new orchid hybrids raised in the Botanic 
Gardens, prepared by Mr. M. R. Henderson and Mr. G. H. Addison, were 
accepted for publication by the Orchid Review of London. Such descriptions, 
which are necessary under the Rules of Botanical Nomenclature to validate 
the names of new hybrids, have hitherto appeared in the Malayan Orchid 
Review, which is the most suitable place for them, but unfortunately this 
periodical has not been published since 1950,
