NOTES ON NEW ENGLAND HEPATICAE,— XV. 
ALEXANDER W. EVANS. 
(Plate 126.) 
THE genus Nardia is well represented in New England. Of the six 
species so far reported N. hyalina and N. obovata belong to Lindberg's 
subgenus Eucalyx, a group which Breidler has raised to generic rank. 
Two of the other species, N. scalaris and N. Geoscyphus, belong to the 
subgenus Eunardia, while the remaining species, N. crenulata and 
N. erenuliformis, form a connecting link between Eucalyx and Junger- 
mannia. For a number of years the writer has been puzzled by a 
species of Nardia which is closely related to N. hyalina and N. obovata. 
It has been observed in several mountainous localities, especially in 
the White Mountains, and seems to retain its distinctive features, 
even while exhibiting a considerable range of variability. This 
species is here proposed as new, and the characters of the two allied 
species are discussed at some length for the sake of comparison. 
Another interesting addition to be reported is Cephalozia Loitles- 
bergeri, a species recently recorded from Nova Scotia. At the close 
of the paper a few additions to local state floras and a revised census 
of New England Hepaticae are given.
