INTRODUCTION 
The following is a third edition of our list of seeds of 
herbaceous plants, trees and shrubs. These seeds are available 
only for exchange with Botanic Gardens, and other regular 
correspondents of our Institution, being not for sale. 
In order to prevent misunderstanding it may be emphasized 
that our seed list is not issued annually, but is meant to be used 
for several years. As it is impossible to keep seeds in stock for 
a long period in the tropics, they are only available for 
distribution immediately after harvesting. 
In the present list the families are no longer arranged 
systematically, the alphabetical order which is more in 
accordance with the purpose and the practical use of this 
publication being chosen from now on.
