1909] Flora of the Boston District,-— IV 15 
REPORTS ON THE FLORA OF THE BOSTON 
DISTRICT,— IV. 
THE Local Flora Committee of the New England Botanical Club 
wishes to thank the botanists who have aided this work by contribut- 
ing card-records covering their herbaria. ‘The reports in regard to 
species included here have been considerably more numerous than 
those previously furnished, and it is hoped that the interest will con- 
tinue. 
No plant is included in this list unless it is known to be represented 
by at least one extant specimen. It has seemed best, however, to 
supplement such records, where they are few, by references drawn 
from the three principal local floras which cover parts of the region. 
There are also numerous citations from Baldwin’s Orchids of New 
‘ngland, which are interesting and have therefore been included. 
These printed records are in each case given after the records of actual 
specimens reported to the Committee.
