REPORT OF THE HONORARY CURATOR OF THE COLLECTION 
OF FOSSIL PLANTS 
Dr. N. L. Brirron, Director-1n-CHIEF. 
Sir: I have the honor to report as follows upon the 
activities in connection with the paleobotanical work of 
the Garden during the year IgI5. 
The cataloguing of the type and figured specimens in 
the collections was continued by Mr. E. W. Humphreys 
and is now practically completed. 
In order to add to the educational value of the museum 
exhibits, five photographic enlargements were installed in 
the cases of Paleozoic plants, representing restorations of 
some of the best known elements of the Carboniferous 
flora (Lepidodendron, Sigillaria, etc.). 
One collection of Pleistocene plants from the Don River 
Valley, Ontario, sent by Professor A. P. Coleman, of the 
University of Toronto, was examined and reported upon 
and duplicate specimens retained for the Garden collection. 
Specimens of Cretaceous plants collected personally and 
by Mr. Humphreys at Glen Cove, New York, were sub- 
jected to preliminary examination and Mr. Humphreys, 
under my direction, made a study of all the unidentified 
Tertiary plants from Florissant, Colorado and supplied 
definite or tentative determinations for all the specimens. 
About twenty specimens were received and accessioned 
and sixteen volumes and pamphlets were added to the 
paleobotanical library. All of my time which could be 
spared for the purpose was utilized in work on the fossil 
flora of Alaska for a forthcoming monograph of the United 
States Geological Survey. Two papers based upon this 
work were presented on September g in connection with 
the program of the Twentieth Anniversary Celebration of 
the Garden. It was also my privilege, on October 23, 
to deliver a lecture on the fossil plant collections of the 
Garden in the regular Saturday afternoon course. 
Respectfully ee 
RTHUR HOLLIcK, 
Honorary Curator of the Collection of Fossil Plants.
