number of duplicates available from this collection and the other half is 
being reserved for the Gardens’ herbarium when the balance which is now 
against it shall have been made good. The Gardens’ herbarium is very 
deficient in plants from New Guinea, the only large set which it possesses 
being the late Mr. C. E. Carr’s which is unworked. As Ledermann’s 
collection has been studied by specialists and contains many new species, 
the acquisition of the duplicates for the Gardens’ herbarium is most valuable. 
In return for the Department’s services in identifying his specimens, 
Mr. A. Vesterdal 'of the Danish East Asiatic Company presented to the 
herbarium numerous specimens collected by him and his assistants from the 
Chantaboon-district in the east of Eower Siam. The flora of Siam is so 
closely related with that of Malaya that the two cannot profitably be studied 
apart yet the Gardens’ herbarium is also deficient in Siamese plants. 
Mr. Vesterdae’s gift is therefore much appreciated. 
Over 6,500 specimens were mounted and incorporated in the herbarium 
during the year. Most were from the late Mr. Carr’s collections from 
New Guinea. 
Six hundred and twenty-two specimens were sent on loan to the 
following institutions:—Arnold Arboretum, U.S.A.; Berlin; Buitenzorg; 
Bureau of Plant Industry, U.S.A.; Kepong, E.M.S.; Kew; Leiden; Paris; 
and Uppsala. Mr. Symington revised the material of Magnoliaceae and 
Polygalaceae.
