Note to Chapter Members. Please take notice. In order to secure 

 greater uniformity in the writing of labels we will give in future the author- 

 ity in full as well as name of plant. In matters of nomenclature we 

 endeavor to follow the best usage— this often necessitates one or more cross 

 references to be made on ones own label, at least till such time as the newer 

 name is well fastened in the memory. 



Another suggestion we make is that members indicate on their list sent 

 to the Secretary, the geographical location of the various species so that an 

 intelligent choice may be made by those requesting specimens. When the 

 same moss is offered again and again it would often save sending for it from 

 a locality already well represented in ones herbarium. A. M. S.
