452 PROCEEDINGS OF THE ACADEMY OF [1879. 



Mr. F. L. Scribner has continued his careful and scrutinizing 

 work upon our grasses, mounting them as he progresses, and we 

 may expect an early completion of so much of the work as relates 

 to the North American Herbarium. 



The Conservator has mounted and ticketed that portion of the 

 North American Herbarium which extends from the Order Good- 

 eniacea? to Order Gentianaceaj inclusive, and hopes to continue 

 the work. 



The accessions to our collection have been constant, extensive, 

 and valuable. The number of species received during the year 

 has been 2181, of which a good proportion were new to our shelves. 

 All these have been carefully poisoned, labeled, mounted, and 

 distributed in the proper orders. Mr. C. F. Parker has been of 

 most essential service in this work, giving us many hours of labor 

 over and above his engagements with the Academy. 



Among the valuable additions of the year may be specially 

 mentioned G23 species of Florida plants, embracing many new 

 and rare species, collected by Dr. A. P. Garber, of Columbia, Pa., 

 and by him generously presented to the Academy ; and many 

 hundreds of rare plants from Northern and Central Asia, North- 

 ern, Southern, and Central Africa, Borneo, Kerguelen Land, 

 Polynesia, California, Oregon, etc., presented by Dr. Asa Graj', 

 of Cambridge, Mass. 



A complete list of the donations during the year is appended 

 to the report now respectfully submitted.
