NOTES ON NEW ENGLAND HEPATICAE,— XI. 
ALEXANDER W. EVANS. 
In the last paper! of this series the rare Neesiella pilosa, a member 
of the Marchantiaceae, was reported for the first time from New 
England. The scanty material which served as the basis for this 
record was collected in 1898 by F. G. Floyd, at the base of a limestone- 
bearing cliff on Willoughby Mountain in northern Vermont. During 
the past summer it was the writer’s good fortune to visit this interest- 
ing botanical region under the guidance of Miss Annie Lorenz, to 
whom it had long been familiar. As a result of this visit several 
species were added to the hepatic flora of Vermont, four of which 
represent additions to the New England flora as well. Of these four 
species two, Clevea hyalina and Neesiella rupestris, belong to the 
Marchantiaceae. These are especially worthy of note because the 
total number of Marchantiaceae known from New England is only ten, 
and because there is little probability that this number will be materi- 
ally increased. The other additions include Lophozia grandiretis 
and the curious Diplophyllum gymnostomophilum, a species which 
has been shifted about from one genus to another since it was originally 
described in 1896. The paper discusses also the synonymy of Lo- ` 
phozia quinquedentata and Cephalozia media, proposes a new name in 
the genus Plagiochila, and is concluded by a list of additions to local 
state floras and a census of New England Hepaticae according to the 
information now at hand.
