Three very dry spring and summer seasons in succession have done much 
to reduce the amount of the more abundant species, so that, although the plants 
may be found in the same place year after year, it becomes increasingly difficult 
to collect enough of any one kind for distribution or for class work. 
As before, hearty thanks are due to Miss Haynes and Dr. Conklin for their 
unfailing encouragement and painstaking assistance in determining specimens. 
Duplicates of all species listed below have been sent to the Society Herbarium. 
The arrangement of names follows the plan of Miss C. C. Haynes’s Ex- 
change List of the Hepaticae of the United States and Canada.
