A BRYOLOGICAL MEMORIAL MEETING AT COLUMBUS, OHIO. 



Columbus was the home for many years of William S. SuUivant 

 and Leo Lesquereux, two names which will always awaken love and 

 reverence from all students of North American mosses and hepatics. 

 It is ten years since the death of Lesquereux, and twenty-six years 

 since Sullivant died, and this last quarter of a century has seen a 

 marked extension of the limits of bryological study, and a large in- 

 crease in the number of students. It seems a fitting time and place 

 to take a survey of the field, review the past and make plans for the 

 future, and hence it is proposed to make the coming meeting of the 

 American Association for the Advancement of Science, which is to 

 be held at Cohmibus, the occasion for a memorial day in honor of the 

 Nestors in American Bryology, and to call on all botanists and botani- 

 cal magazines to help make the occasion a memorable success. It is 

 proposed to present a series of papers, illustrated by photographs, 

 specimens and microscopical slides and books and pamphlets, under 

 the following topics: 



Historical papers and collections showing the bryological work 

 of Hedwig, Palisot de Beaubvois, Michaux, Muhlenberg, Bridel, 

 Torrey, Drummond, Hooker and Wilson, Greville, Sullivant and Les- 

 quereux, James and Watson, Austin, Ravel, Wolle, Eaton and Faxon, 

 Mliller and Gottsche. Supplementing these there will be shown col- 

 lections of specimens, macroscopic and microscopic, illustrating the 

 monographic work of recent American students. 



If foreign students who have worked on North American bryo- 

 phytes can be persuaded to co-operate with us, the following will be 

 asked to contribute : Bescherelle, Brotherus, Cardot, Dixon, Kind- 

 berg, Mitten, Pearson, Roll, Stepham and Warnstorf. 



An effort will be made to secure the loan of type specimens and 

 illustrations from the following sources: The Academy of Natural 

 Sciences of Philadelphia, Academy of Sciences of New York, Colum- 

 bia University, Harvard University, The National Museum, The 

 Ohio State University, The University of Wisconsin and Yale 

 University, as well as from private collections. It is also intended to 

 exhibit any portraits, autograph letters, and type specimens and 

 drawings of special interest which may be loaned for the occasion, as 

 well as presentation copies of books and pamphlets. 



The following committee of organization will gladly answer 

 questions and give assistance to those wishing to contribute: 



Prof. Charles R. Barnes, University of Chicago; Mrs. N. L. Brit- 

 ton, New York Botanical Gardens; Prof. W. A. Kellerman, Ohio 

 State University ; Dr. George G. Kennedy, Readville, Mass. ; Prof. L. 

 M. Underwood, Columbia University.
