PREFACE. 
Under direction of the Board of Trustees, the seventh 
annual report of the Missouri Botanical Garden is pre- 
sented to the public. The sixth report was issued May 3, 
1895. 
The reports of the Garden are sent regularly to scientific 
institutions and journals in exchange for publications or 
specimens desirable for the library, herbarium, or plant- 
houses of the Garden. So far as possible reprints of the 
botanical articles which they contain are sent to botanists 
occupied with a study of the same subjects. 
Any of the Garden publications not out of print may be 
purchased, at approximately the cost of publication, from 
Dr. A. E. Foote, of Philadelphia, the Cambridge Botanical 
Supply Co., of Cambridge, Mass., W. Wesley & Son, of 
London, B. Friedlander & Sohn, of Berlin, or the under- 
signed.
