Mr. Russell contributed much to the general knowledge 

 of botany in Essex County, but his most extensive collec- 

 tions were made in other places. 



The only attempt at an enumeration of county plants, 

 as such, is that of Mr. Cyrus M. Tracy, of Lynn. It 

 was intended to give a list of the flowering plants found 

 in that region and contained 546 species. Besides pos- 

 sessing a very happy gift as a botanical lecturer, Mr. Tracy 

 has contributed several valuable articles upon local botany 

 to the publications of the Essex Institute and elsewhere. 



Mr. Geo. D. Phippen, of Salem, whose notes on the 

 native plants have materially aided the writer, has often 

 presented the subject of botany at meetings of the In- 

 stitute, and has written several articles of interest upon 

 the subjects which have been published in various 

 Ijlaces. Mrs. C. N. S. Horner, of Georgetown, a most 

 excellent botanical collector, published a list of the plants 

 of that region in the Georgetown Advocate in 1876. Mr, 

 Calvin Pool, of Rockport, prepared a somewhat smaller 

 list of plants of Cape Ann, which was published in 

 "Pigeon Cove and vicinity " in 1873. Mr. S. B. Buttrick, 

 whose years do not diminish his interest in botany, and 

 who is ever on the alert to find some rare flower, has con- 

 tributed several lists of plants to the earlier numbers of 

 the Proceedings and Bulletin of the Essex Institute, as 

 also have Dr. G. A. Perkins, of Salem, chairman of the 

 botanical section of the Peabody Academy of Science, 

 Mr. Geo. F. H. Markoe, now of Boston, Rev. Mr. Chute, 

 formerly of Lynnfield, and many others. Dr. Henry 

 Wheatland, although not claiming to be a botanist, has 

 often aided those who did, by his assistance in revising 

 the articles for the publications of the Institute while act- 

 ins as the editor. Mr. S. P. Fowkr, of Danvers, one of 

 the older botanists and a companion of Oakes and Osgood,
