28 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. [Bull. 
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 Hepatic 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 
‘o 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 S. dasyphyllum, 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 Malden, 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 exsiccate devoted exclusively to North 
American Peat 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 Hepatic within the state has been almost 
doubled. The seven following species, occurring in Con-
