PREFACE. 



The present paper by Dr. S. F. Blake, of the Bureau of Plant 

 Industry, United States Department of Agriculture, contains a list 

 of the native names and uses of the plants collected by the botanists 

 who accompanied the Economic Survey Mission sent out in the 

 spring of 1919 by the United States Department of State for the 

 purpose of making a survey of the economic resources of the region 

 in eastern Guatemala and Honduras lying between the Motagua 

 and Chamelecon Rivers. The time spent in the field by the expedi- 

 tion was so short that the list is necessarily incomplete, but it con- 

 tains much new and useful information, especially on the wild 

 medicinal plants, and should be of service to travelers who may 

 visit the same region. 



Frederick V. Coville, 

 Curator of the United States National Herbarium.
