3. Collectio-s desired. - The things ’which I 
— * 
particularly want to get arAthe following.- 
(a). All members of the .family Dipterocarpaceae 
that are found in flower or £n fruit. - A number of forms 
from the eastern and -southern parts of the Malay Peninsula 
are evidently very closely related to S rawak forms and, 
in some cases, Iwill he unable to identify them without 
comparison with Sarawak material. I am also art.dually 
assembling material for a monograph of the group, which I 
hope jtsome day to finish, ijr.unber of duplicates and also 
a wood sample will be wanted with each number collected. 
(V Commercial Timber Trees.- All trees that are*rec¬ 
ognized as of commercial importance are of interest to me and 
L~i J- 
I want flowering and fruiting material and wood specimens. 
(c) Oilier economic plants, - Any plant which has now, 
or is likely to have in the near future, economic importance 
is of in<er st to me and should be collected. 
(a) Localitities for collecting. 
' X 'am finding in the Milay Peninsula,that it 
is very important to have collect ons from all districts. 
I wi uld like. for the collector to work in each of the 
districts, of St rawak. It wilt he possible to furnish him 
will a list of known' names, and he can .Look for the same 
trees ir each district' visitel. On a particular trip,he may 
find only a few of the tilings in flower or fruit, but he can 
locate particular trees for examination on subsequent 
visits and can do genera,! collecting* It is proposed 
that his trips shall be directed only to the lowland 
forests. The altitudinal range rill be determined^ by the 
place at vrtrich the Diptprocarps cease to occur.
