PREFACE. 
Under direction of the Board of Trustees, the fourteenth 
annual report of the Missouri Botanical Garden is pre- 
sented to the public. In addition to the administrative 
reports of the officers of the Board and the Director, this 
volume contains an important revision of the genus Loni- 
cera, by Mr. Alfred Rehder, of the Arnold Arboretum, and a 
catalogue, by Mr. C. E. Hutchings, of the additions which 
have been made to the Sturtevant Prelinnean Library, of 
the Garden, since the publication of the catalogue of the 
original collection, in the seventh report. 
The thirteenth report was issued on July 28th, 1902, 
which fixes the date of publication of the paper on Yuc- 
ceae, forming the larger part of the volume, separates of 
which were distributed on the 30th of the same month. 
These reports are sent to scientific institutions and 
journals in exchange for publications or specimens desir- 
able for the Garden, and, when possible, reprints of the 
botanical articles they contain are presented to botanists 
occupied with a study of the subjects they refer to. Any 
of the Garden publications not out of print may be pur- 
chased at approximately the cost of publication from A. I. 
Eriksson, Tufts College, Mass.; R. Friedlinder & Sohn, 
Berlin, Germany; W. Wesley & Son, London, England; 
or the undersigned.
