Botanical Section. 



Early in the year the work of putting the species of flowering plants 

 into covers was completed, which will prove not only a convenience 

 in studying, but will also secure a decrease in the possible breakage of 

 specimens. 



The most notable addition during the year has been the Albert 

 Commons Herbarium of Delaware plants, representing his collecting 

 during half a century. It is probably the most complete series of the 

 flora of the State, including not only the flowering plants and ferns, 

 but also the lower forms, fungi, etc. The collections were presented 

 to the Academy by Messrs. Frank W. and Howard W. Commons, of 

 Minneapolis, Minn. 



Other donations include a collection of 50 species of Bucks County, 

 Pa., Crataegus from Dr. C. D. Fretz; 160 Crataegus and other trees 

 and shrubs from the Arnold Arboretum ; 250 specimens of plants from 

 the eastern United States from E. B. Bartram, and smaller collections, 

 aggregating about 150 specimens, which will be noted in detail in the 

 Additions to the Museum. 



The Section has purchased 500 specimens of California and Nevada 

 plants from A. A. Heller; 40 specimens of Crataegus from Willard W. 

 Eggleston and 100 Mexican mosses from C. G. Pringle. 



The Conservator spent the time from May 22 to June 2 of the present 

 year in the Bermudas, w T here a collection of about 250 plants was made, 

 and, though not large in species, enabled him to determine some 

 uncertain records, besides adding a number to the known flora of the 

 islands. The results of this and two previous trips are embodied in 

 a paper in the current number of the Proceedings. 



The Philadelphia Botanical Club has continued to hold its meetings 

 in the herbarium of the Academy during the year, and through the 

 energy of its members 2,100 sheets have been added to the local 

 collection, in the care of which Mr. Samuel S. Van Pelt has continued 

 his valuable services as Curator. 



Acknowledgment is made of the services of Miss Ada Allen as 

 assistant in the herbarium during the year.
