and 110 genera, as well as much loose unclassified material. The 

 Herbarium now contains a grand total of 2197 mounted specimens, 

 of which 1835 specimens representing 493 species and varieties, an<J 

 125 genera, are native, and 362 specimens representing 324 species 

 and varieties, and 108 genera, are foreign. 



The foreign herbarium which contains the generous contributions 

 of A. Bruce Jackson, Eikichi lishiba, Shutai Okamura, W. H. Lett; 

 W. E. Nicholson, the late F. Renauld, and W. W. Watts, has been 

 placed in red genus covers and the whole has been classified accord- 

 ing to Engler & Prantl. 



Many members in the United States have contributed native speci- 

 mens, and a liberal series from G. M. Pendleton, Sisson, California,' 

 is soon to be added to the collection, but a much wider correspond- 

 ence is desired. 



The Department is in possession of abundant and excellent dupli- 

 cate specimens which only await exchange with those who may wish 

 to simultaneously enrich their own and the Society's herbarium. With 

 the collaboration of all it is sincerely hoped that the ensuing year will 

 bring renewed bryological zest and activity to our members who 

 should bear in mind the herbarium and its needs. Under such con- 

 ditions the collection cannot fail to grow both in extent and value, 

 while the strength of common interests will aid fraternity among the 

 many members of the Sullivant Moss Society.
