NOTE. 
Tee map supplied with this fascicle is intended to be bound at the 
end of the volu me, but is given now so as to be immediately 
available. Botanists who intend to make use of this numerical list in 
the garden are advised to have the map cut along the folds and 
mounted on linen. 
Although the garden is gone over systematically at intervals to 
replace tickets that have been lost or—as sometimes happens—mali- 
ciously or thoughtlessly torn off, still tickets that should be present may 
not always be found. In such cases the numbers of adjoining plants 
should give a clue to the missing ones. Since the ticketting of the 
plants was finished early in 1909 a number of plants have died, been 
blown over or cut out in the course of improvement of the garden. 
The numbers of such plants—that need not of course be looked for— 
are indicated in the list by a t after the name of each plant that has 
disappeared. A list of the numbers of plants that disappear is kept 
up to date in the Superintendent’s office, and copies will be supplied— 
on application—to those who desire to use this list in the garden.
