SECOND REVISED LIST OF NEW ENGLAND 

 HEPATICAE. 1 



Alexander W. Evans. 



In 1903 the writer 2 published a preliminary list of New England 

 Hepaticae, in which 123 species were reported. Of these, 75 were 

 accredited to Maine, 81 to New Hampshire, 67 to Vermont, 76 to 

 Massachusetts, 65 to Rhode Island, 94 to Connecticut, and 31 to all 

 six of the New England States. From 1902 to 1912 a number of 

 noteworthy species were discussed in this journal in a series of Notes 

 on New England Hepaticae, many of the species representing additions 

 to the flora. This series comprised ten numbers, the first appearing 

 in November, 1902, and the last in November, 1912. In 1913 the 

 writer 3 published a Revised List of New England Hepaticae, in which 

 much of the information found in these Notes was incorporated. In 

 this list 177 species were reported, 123 being accredited to Maine, 

 130 to New Hampshire, 109 to Vermont, 97 to Massachusetts, 77 

 to Rhode Island, 134 to Connecticut, and 53 to all six states. 



Since the appearance of the Revised List the series of Notes has 

 been continued, seven additional numbers having been published, 

 as follows: the eleventh in April, 1914 (16: 62-76); the twelfth in 

 June, 1915 (17: 107-120); the thirteenth in April and May, 1916 

 (18: 74-85, 103-120. pi. 120 +/. 1-Jfi); the fourteenth in December, 

 1917 (19: 263-272); the fifteenth in September, 1919 (21: 149-169. 

 pi. 126 +/. 1-14); the sixteenth in December, 1921 (23: 281-284); 

 and the seventeenth in May and June, 1923 (25: 74-83, 89-98). 

 In these Notes considerable new information regarding the distribution 

 of the New England species is given, and this is included in the Second 

 Revised List found below. As in the preceding lists the sign + 

 indicates that an herbarium specimen has been seen, the sign — that 

 a printed record has been found. In accordance with the prevailing 

 views on the classification of the Hepaticae more families are recog- 

 nized in the new list than in the earlier lists. Of these families the 

 first four belong to the order Marchantiales, the next eleven to the 

 Jungermanniales, and the last to the Anthocerotales.
