Exsiccati," issued by Renauld and Cardot during the last 

 fifteen years, Professor Eaton supplied a number of species 

 from Connecticut, and these will be especially indicated in 

 the list which follows. 



The Peat Mosses (Sphagnales) and the Hepaticae have 

 received rather more attention than the True Mosses, and the 

 majority of the additions which have been made in these two 

 groups have already been recorded. In the Berzelius List only 

 three species of Sphagnum are included. About 1890, how- 

 ever, Professor Eaton and the senior writer began to collect 

 these interesting plants systematically, and to submit specimens 

 to Dr. C. Warnstorf, then of Neuruppin, Germany, for deter- 

 mination. In this way the number of known species was 

 markedly increased. In 1892 Warnstorf described as new, 

 under the name 5". dasyphylliim, a species from East Haven, 

 which is still known from this locality only. In 1893 Professor 

 Eaton published his " Check-List of North American 

 Sphagna," indicating the geographical distribution of each 

 species, so far as known at that time. Although Connecticut 

 is included in several of the wider ranges, only five species are 

 definitely recorded from the state, all of these being additions 

 to the Berzelius Catalogue. The check-list was prepared for 

 the convenience and guidance of Professor Eaton and Mr. 

 Edwin Faxon, of Maiden, Massachusetts, who were collecting 

 sets of North American species for distribution. These sets 

 were issued in 1896 by Dr. George F. Eaton, under the title 

 " Sphagna Boreali-Americana Exsiccata," and constitute the 

 only published exsiccatas devoted exclusively to North 

 American P'eat Mosses. They include twenty-nine numbers 

 from Connecticut, representing fourteen species. Three 

 species from the state had already been distributed by Warn- 

 storf, in the fourth series of his " Europaeische Torfmoose." 

 In 1906 Andrews listed nineteen species of Sphagnum from 

 Connecticut, and twelve additional species have been recently 

 determined by Warnstorf from Connecticut specimens, so that 

 thirty-one species in all are now known. 



Since the publication of the Berzelius List the number of 

 known species of Hepaticae within the state has been almost 

 doubled. The seven following species, occurring in Con-
