NOTES ON NEW ENGLAND HEPATICAE ,— XVI. 1 

 Alexander W. Evans. 



The difficult genus Scapania continues to occupy the attention of 

 European students of the Hepaticae, and many new species have been 

 proposed during recent years. Some of these have been accepted 

 without question, others are now regarded as "small" species, while 

 still others have been reduced to synonymy or to varietal rank. In 

 the present paper one of the most distinct of these recently described 

 species, S. hyperborea, is recorded from New England for the first 

 time, and it is probable that others will eventually be discovered. The 

 paper records also another species of Nardia from New England 

 (making eight in all), lists a series of additions to local state floras 

 and concludes with a revised census of New England Hepaticae.

 count of this rare species, 2 citing specimens from New Jersey, West 

 Virginia and Illinois. Its discovery in Connecticut extends its 

 known range to the northward, and the following specimens re-

 The plants from the Shepaug River grew in situations which are 

 clearly submerged at certain seasons. When fresh the leaves were
