 A most gratifying announcement is the completion of the great 

 task of mounting all the specimens in the herbarium of North 

 American plants as covered by Grays Synoptical Flora. This was 

 commenced in 1878, by the Conservator, Mr. John H. Redfield, as- 

 sisted at various times by Messrs. F. Lamson Scribner, Isaac Burk 

 and the late Charles F. Parker. 



The encouraging growth of the herbarium noted in our former 

 annual reports, still continues. The large number of 1039 species 

 were added to our former list, making 28,306 as the total number 

 of species of vascular plants represented in the herbarium.
