PREFACE 



The accompanying paper by A. S. Hitchcock, Systematic Agrostol- 

 ogist of the United States Department of Agriculture, entitled Cata- 

 logue of the Grasses of Cuba, is the result of an exhaustive study of 

 the material in the United States National Herbarium and in the 

 herbarium of the Estacion Central Agronomica de Cuba. It was 

 chiefly through the efforts of Mr. Carl F. Baker, who obtained large 

 collections in Cuba, that the specimens were made accessible to Mr. 

 Hitchcock. It is hoped that this paper will be followed by similar 

 ones upon other groups.

 Acting Curator.
