used to vary the general red and white scheme. On the 
balcony overlooking the display house will be shown many 
begonias and a few hundred lilies of various varieties. 
In point of beauty the December show bids fair to rival 
that of the chrysanthemums during the month of November. 
ANNALS OF THE MISSOURI BOTANICAL GARDEN 
_ It does not seem to be generally known in St. Louis that 
in addition to the BuLLeTin, the Garden publishes a quar- 
terly known as the Annals of the Missouri Botanical Garden. 
This journal is devoted exclusively to scientific papers con- 
tributed by members of the Garden staff, by graduate stu- 
dents in the Shaw School of Botany of Washington Univer- 
sity, or by botanists using the extensive facilities offered by 
the Garden. Except when exchanged for an equivalent pub- 
lication, the Annals is supplied only on subscription, $3.00 
annually. : 
The scope and character of the Annals may be Judged from 
the table of contents of the three volumes which have ap- 
peared thus far.
