A Bryological Memorial Meeting at Columbus, Ohio. 



i 



Columbus was the home for many years ofWiUiam S. SulHvant 

 and Leo Lcsquereux, two names which will always awaken love 

 and reverence from all students of North American mosses and 

 hepatics. It is twenty-six years since Sullivant died, and this last 

 quarter of the century has seen a marked extension of the limits of 

 bryological study and a large increase in the number of students. 

 It seems a fitting time and place to take a survey of the field, re- 

 view the past and make plans for the future, hence it is proposed 

 to make the coming meeting of the American Association for the 



Advancement 



Memorial 



Byrology and to call on all botanists and botanical journals to help 

 make the occasion a memorable success. It is proposed to present 

 a series of papers, illustrated by photographs, specimens and mi- 

 croscopical exhibits under the following topics : Historical papers 

 and collections illustrating the bryological work of Hedwig, PaHsot 

 de Beauvois, Michaux, Muhlenberg, Bridel, Torrey, Drummond, 

 Hooker and Wilson, Greville, Sullivant and Lesquereux, James 

 and Watson, Austin, Ravenel, Wolle, Bolander, Eaton and Faxon, 

 and Miiller. Supplementing these there will be shown collections 

 of specimens, macroscopic and microscopic, illustrating the mono- 

 graphic work of recent American students. 



If foreign students who have worked on North American byro- 

 phytes can be persuaded to cooperate with us, the following will 

 be asked to contribute : Bescherelle, Brotherus, Cardot, Dixon, 

 Kindberg, Mitten, Pearson, Roll, Stephani, and Warnstorf. 



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

 and illustrations from the following sources : Academy of Natural 



m 



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

 umbia University, Geological and Natural History Survey of 

 Canada, Harvard University, National Museum, Ohio State Uni- 

 versity, University of Wisconsin, and Yale University, as well as 

 from private herbaria and collections. ■ It is also requested that 

 any portraits, autograph letters and type specimens and drawings
