REPORTS ON THE FLORA OF THE BOSTON 
DISTRICT,— XVI. 
Tue records on which the reports on the Gramineae are based have 
‘been unusually full, except in the case of some of the more recently 
described species. Over 3500 of these records are already on file with 
the Committee. These represent the Gramineae of the Gray Her- 
barium, the Herbaria of the New England Botanical Club, Boston 
Society of Natural History, Peabody Academy of Science at Salem, 
Wellesley College and Yale University (Dr. C. W. Swan’s collection), 
and the personal herbaria of J. R. Churchill, Walter Deane, F. F. 
Forbes, F. W. Grigg, F. Tracy Hubbard, C. H. Knowlton, John 
Murdoch, Jr., and R. A. Ware. wy, 
The collections from the Peabody Academy at Salem and from the 
Swan Herbarium at Yale were sent to the Gray Herbarium, where they 
were diligently verified. Prof. M. L. Fernald and Mr. F. Tracy 
Hubbard have been of special service in this work. The ranges given 
are based on actual specimens. 
In studying Panicum constant use has been made of the Hitchcock 
& Chase monograph, Contrib. U. S. Nat. Herb. xv. 1910.
