jjnembers of the Gardens staff published many articles on garden 
plants in Malaya. 
Dr. Furtado*8 botanical work . Dr. Furtado (appointed 
1923 ) has studied especially aroids and palms, and has published 
several papers on Malayan plants in both families. He is now 
making studies on cultivated edible aroids (keladia) and rattans, 
both of which are Important locally from an economic standpoint. 
Mr. Henderson^ a botanical work . Mr. Henderson published 
an account of the limestone flora of Malaya. He also made exten- 
sive studies and notes of the large genus Kugenia (unpublished). 
Mr. C # K. Qarr*e botanical work . Mr. C.J 2 ^. Carr, a planter 
stationed at Terabeling, Pahang, was an enthusiastic botanist and 
devoted much time (1928-1933) to collecting and studying Malayan 
03?chids, in which work he collaborated with Gardens officers. This 
resulted in a great increase in our knowledge of local orchids. 
After Mr. Carr's death his herbarium was acquired for the Gardens. 
The Herbarium . Botanical collections in Malaya, and to 
a small extent in Borneo and Sumatra, have been regularly carried 
on every year. Sveiy species collected is labelled with a Singapore 
Field Number; the numbers (begun in 1915) now reach nearly 40,000. 
Additional specimens are always collected, and are sent (when named) 
to other botanical institutions in exchange for their specimens. 
In this way a large number of herbariian specimens of plants from 
neighbouring countries have been obtained from Buitenzorg, Manila 
and elsewhere. An average of nearly 5,000 mounted specimens has 
been added to the herbarium annually. 
The Library . Many additions have been made to the library. 
Periodicals have been received in exchange for the Gardens Bulletin, 
and others purchased. Many Important old botanical works dealing 
with Malayan plants have been purchased, as well as new publications. 
A card catalogue of the library was begun in 1923, and subsequently 
maintained. A subject index of matters relating to local plants, 
and to tropical plants generally, was begun in 1930 and maintained; 
this now consists of some 15,000 cards. 
Horticultural work in general . This has been under the 
care of officers trained in horticulture at the Royal Gardens, Kew, 
among whom Mr. J.C. Nauen has been outstanding. Since 1919 the 
general standard of maintenance of the Gardens has steadily improved, 
and also a large number of new ornamental plants have'been introduced 
which have provided a greater variety of interest. Jfivery year many 
plants and seeds are introduced for trial from all parts of the 
world, and of these a few are successful. Groups of ornamental 
plants in which considerable additions have been made are Hibiscus, 
Bougainvillea, Lantana, Plumeria and conifers. Hibiscus came chiefly 
from Honolulu, from 1925 onwards; the planting of the collection by 
the Main Gate Road on lawn J began in 192?. In 1919 only four 
Bougainvillea varieties existed in the Gardens. ’’Mrs. Butt” was 
brought in 1923 from Kew by Mr. Burkill, but most of the new varie- 
ties came after 1934, from Ceylon, Calcutta, Madras, Australia and 
the West Indies (via London). They are planted on lawn B, behind 
the Ganna beds. Plumerias came from Honolulu, and others were 
raised from seed locally; they are on the south side of the band- 
stand hill. The best Lan tanas were a collection of dwarf hybrids 
obtained by seeds from California, in beds on the Bandstand Hill. 
Conifers came from Ceylon, Japan, Australia, Hong Kong and Africa, 
and are planted near the office on lawn D. 
Most of these plants were obtained by exchange from other 
Botanic Gardens. This was greatly helped by the publication of a 
Singapore seed exchange list in 1929 (reprinted twice since then), 
which was sent to most of the Botanic Gardens in the world. As a
