XVIII. PUBLICATIONS 
67. The first edition of the Revised Flora entitled Orchids of Malaya 
by R. E. Holttum published in 1953 was completely sold and a second edi¬ 
tion is now being prepared and will be printed in 1957. The book on Malayan 
Orchid Hybrids by M. R. Henderson and G. H. Addison was published 
during the year by the Government Printer. It contains descriptions of over 
200 hybrids which have been raised in Malaya or have been introduced from 
other countries, together with information on their cultivation. There are 
usually two plates of each orchid, one showing a spray and the other an 
individual flower. It is hoped that subsequent volumes will be produced, so 
that this valuable work may be kept up-to-date. 
68. Volume XV of the Gardens ’ Bulletin was published on the 20th 
November. Owing to its length (383 pages) it was published as a full volume 
and not issued in Parts. It contains a long and important article on Dr. 
Furtado’s revision of the Genus Calamus in the Malayan Peninsula. Almost 
sufficient copy is now to hand to publish a further volume of the Gardens’ 
Bulletin. 
69. The revenue from the sale of publications at the Gardens was 
$830. It should be remembered that the books written by members of the 
Gardens’ staff, past and present, and published by the Government Printer 
are sold direct by the Printing Office. There is a ready demand for the 
small pamphlets on Malayan Garden Plants. Three of the existing six pam¬ 
phlets are out of print, having sold some 2,000 copies each, and will be re¬ 
printed. Three new pamphlets have been prepared and it is hoped that they 
will be published shortly.
