Annals 
of the 
Missouri Botanical Garden

INTRODUCTION 
In order to provide for the printing of scientific papers, which 
formerly constituted a large part of the volume known as the 
Annual Report, the Board of Trustees has authorized а new 
journal, to be known as the ANNALS OF THE Missouni BOTANI- 
CAL GARDEN. Тһе Annals will appear four times а year, in 
March, May, September, and November, and contain only 
scientific contributions from members of the staff of the Garden, 
from the faculty and graduate students of the Henry Shaw 
School of Botany of Washington University, and from vis- 
iting botanists doing all or a part of their work at the Garden. 
The increase in original contributions available for publication, 
due to the additions to the staff and the greater number of 
graduate students, makes it no longer possible to follow the 
practice of the past and print papers from sources other than 
the Garden. 
The publication of а monthly bulletin by the Missouri 
Botanieal Garden, in which appear promptly the annual re- 
ports of the officers of the Board, and of the Director, together 
with popular accounts of the various activities of the Garden; 
and the provision for the printing of scientific papers in the 
Annals, has made it advisable to discontinue the Annual Report, 
which was published each year from 1890 to 1912. Тһе Twenty- 
third Annual Report, therefore, marks the close of this series. 
The Annals will be maintained upon a strict subscription 
basis, using it in exchange only when its equivalent can be 
obtained. Some of the institutions and societies, the publi- 
cations of which have been received in exchange for the Annual
