Plant of about the size and of much the general appearance of 
Hypnum adnatum, Hedw. The position, shape and areolation of 
the branch leaves are also much as in that species, but they are 
more concave, and have the areolation shorter, The stem-leaves 
are shaped somewhat as in Hypnum hispidulum, Brid; but they 
are more concave, and have a more abrupt, longer, and more flex- 
uose point and entire margins. 
Differs from 7hedenia Suecica, as described in Schimper’s Synop- 
sis, mainly in the somewhat rigid and more or less costate leaves.

On the base of trees along the borders of a swamp, near Closter, 
New Jersey; very rare. (First found by me in 1864 on the base 
of a tree, about half a mile suuth of Closter.) (This tree was ent 
the following winter.) I again found it in 1872 ona tree about 
80 rods south-west of the former station, along the east side of 
John Westervelt’s woods. The following species is found on many 
of the trees in the same woods, in close proximity to this.
