PREFACE. 
Under the direction of the Board of Trustees, the tenth 
annual report of the Missouri Botanical Garden is presented 
to the public. The ninth report was issued April 16, 1898. 
In addition to the administrative reports for 1898, which 
contain a summary of the results achieved during the period 
since the manangement of the Garden devolved upon the 
Trustees designated by Henry Shaw in his will, and two 
scientific papers, the present volume contains a biographi- 
cal sketch of the late Dr. E. Lewis Sturtevant, whose gifts 
to the Garden have from time to time been announced in 
these reports, kindly prepared by Professor C. S. Plumb, 
at the request of the Board of Trustees, a list of publica- 
tions issued from the Garden in 1897 and 1898, a list of 
the serial publications received at the Garden library, and 
comprehensive indexes to the contents of the ten annual 
reports of the Garden thus far issued. 
These reports are sent to scientific institutions and 
journals, in exchange for publications and specimens de- 
sirable for the library, herbarium, or plant-houses of the 
Garden. So far as possible, reprints of the botanical 
articles 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 
The Cambridge Botanical Supply Co., of Cambridge, 
Mass., W. Wesley & Son, of London, R. Friedlinder & 
Sohn, of Berlin, or the undersigned.
